The calculated speed is 8 m/s.

The region below the curve in the acceleration vs. time graph can be used to calculate velocity. Similar to the integral in equation, this (1). The area underneath the graph in the first four seconds in this example is just a rectangle with a base of t1=2s and a height of a1=4m/s2.

Therefore, the area is v24=a1

t24=4m/s2

2m/s=8m/s.

Since the particle begins at rest and is not accelerated for the first second, its velocity after 4 seconds is

v (4s) =v24

The mathematical relationship between spring force and the stretch of a spring is F = - k x, where k is spring constant and x is the extension of the spring.

A spring is a material that may be bent by an external force before resuming its original shape.

Many of us use springs on a daily basis, yet we frequently ignore their inertia by treating them like massless objects. A spring's ability to experience displacement when stretched, compression when compacted, and return to equilibrium when free is a very casual process. This fact demonstrates that a spring compresses or stretches a body by applying an equal and opposite force.

Answer:

B

Explanation:

if you drink lots of water while running your less likely to be hot and dehydrated. even if it's the same amount you run which tires your body and causes you to need more water.

It is hot and she is practicing more so she probably needs more water. The correct option is B.

When your body loses more fluid than you take in, you become dehydrated.

When your body's normal water content is reduced, it disrupts the balance of minerals (salts and sugar) in your body, affecting how it functions. Water accounts for more than two-thirds of the healthy human body.

As you lose fluid, your blood becomes more concentrated, requiring your cardiovascular system to work harder to pump blood efficiently. A high blood concentration causes your kidneys to retain more water, causing you to urinate less.

Dehydration occurs when you do not drink enough fluid or lose more fluid than you take in. The severity of dehydration is affected by a variety of factors, including climate, level of physical activity, and diet.

Thus, the correct option is B.

The velocity of the car upon impact is 10.8 m/s, or about 24.2 mph. Velocity is typically measured in units of meters per second (m/s) or kilometres per hour (km/h).

What is Velocity ?

Velocity is a vector quantity that describes the rate and direction of an object's motion. It is defined as the change in displacement over time. In other words, velocity is how fast an object is moving and in what direction.  For example, if a car is traveling north at a speed of 20 m/s, its velocity would be 20 m/s in the northward direction.

First, we can calculate the initial velocity of the car in meters per second:

45.0 mi/hr = 66.0 ft/s

1 mile = 5280 ft

66.0 ft/s x 1 mile/5280 ft = 0.0250 mile/s

1 hour = 3600 s

45.0 mi/hr = 45.0 x 1 mile/1 hour = 45.0 mile/hr

45.0 mile/hr x 1 hour/3600 s = 0.0125 mile/s

0.0125 mile/s x 1609.34 m/mile = 20.12 m/s

The initial velocity of the car is 20.12 m/s.

Next, we can calculate the acceleration of the car using the coefficient of friction and the acceleration due to gravity:

μ = 0.77 (coefficient of friction)

g = 9.81 m/s² (acceleration due to gravity)

a = μg = 0.77 x 9.81 = 7.56 m/s²

The acceleration of the car is 7.56 m/s².

Now we can use the kinematic equation for uniformly accelerated motion to calculate the distance the car will travel before stopping:

v² = u² + 2as

where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance traveled.

Since the car stops, the final velocity is zero:

v = 0

Plugging in the known values, we get:

0² = (20.12 m/s)² + 2(-7.56 m/s²)s

Solving for s, we get:

s = (20.12 m/s)² / (2 x 7.56 m/s²)

s = 53.3 m

Therefore, the car will not stop in time to avoid a collision with the other car, since the stopping distance of the car is 53.3 meters, which is greater than the distance between the two cars (90.0 ft or 27.4 meters).

To calculate the velocity of the car upon impact, we can use the same kinematic equation:

v² = u² + 2as

but this time, the distance travelled is the distance between the two cars, since the car will not stop before hitting the other car:

s = 27.4 m

Plugging in the known values and solving for v, we get:

v = √[(20.12 m/s)² + 2(-7.56 m/s²)(27.4 m)]

v = 10.8 m/s

Therefore, the velocity of the car upon impact is 10.8 m/s, or about 24.2 mph.

When the balance of the forces acting on the object you are acting on results in no changes in motion. Unbalanced forces have an influence on the item that are acting on and do not cancel one another out.

Two things cause this. An object will move if an imbalanced pressure pushes or pulls on it while it is at rest. Forces acting can also cause an item in motion to shift its speed or direction.

Because of unequal power or strength delivered to one side of an item, an imbalanced force results in a shift in motion, pace, direction, or movements. There are forces working against the other side.

When a wire is pulled through a die and stretched six times its initial length, the cross-sectional area reduces according to the length increase. According to Ohm's law,

this change in cross-sectional area influences the wire's resistance, which is directly proportional to its length and inversely proportional to its cross-sectional area. The wire's resistance grows by a factor of 36, which is equal to the square of the stretching factor (6 x 6 = 36). This is due to the wire's length increasing by a factor of six while its cross-sectional area decreasing by a factor of six times six. As a result, the resistance of the wire after stretching it to six times its original length will be  36 times its original resistance, assuming all other factors (such as the resistivity of the material) remain constant.

The marginal propensity to save (MPS) is equal to 0.2. The autonomous spending multiplier (ASM) is equal to 5.

The marginal propensity to save (MPS) is the portion of each additional dollar of income that a person saves. Given that the marginal propensity to consume (MPC) is equal to 0.8, we can calculate the MPS by subtracting the MPC from 1.

MPS = 1 - MPC = 1 - 0.8 = 0.2.

Therefore, the marginal propensity to save is equal to 0.2.

The autonomous spending multiplier (ASM) is the factor by which autonomous spending is multiplied to determine the total change in output or income in an economy. It is calculated using the formula:

ASM = 1 / (1 - MPC).

Substituting the given MPC value of 0.8 into the formula, we get:

The brightness of a light will appear one-fourth times bright when the point source is twice far away.

The reason behind why does a light source seems dimmer or darker as it goes farther away this is that the light coming from the source spreads in all directions. we can see that a campfire no matter what direction we are looking at it from, even if we are flying above and look down, In a flashlight, the body of the flashlight blocks light in some directions and redirects it out the front , so it seems to be shining in only one direction.  But the light bulb inside the flashlight, like the campfire, shines in all directions.

Therefore, if we as are twice as far away from a light source, it should appear one-fourth as bright. Scientists call this as "the inverse squared law." In mathematical terms, we can find out the relative brightness of two objects by comparing their relative distances, squaring the value, and then inverting the value. (Twice as many steps from the wall squared is four, and inverting four gives one-fourth.)

So the light coming from a point source which is twice as far away will appear one- fourth times brighter than its original.

Answer:

Stars are very massive stellar objects, which means that they have a very intense force of gravity. This is the first of the forces entering this "war".

In addition to that, due to the force of gravity that drives the star to contract, the process known as fusion occurs (the union of atoms of one element that results in another element, hydrogen fuses in stars to produce helium). The fusion created in the high temperatures of the center of the star generates an enormous amount of energy (which causes the stars to shine) and a force going outward of the star counteracting gravity, this is the second force in the "war" .

In a stable star these two forces (gravity going inward and the pressure created by the fusion going outward ) are in balance, preventing the star from exploding or collapsing. But eventually the star exhausts its "fuel" (hydrogen atoms) to produce fusion within it (although stars also fuse helium and other heavier elements, but once the hydrogen is finished the star is near its end), which decreases the force outward from the star, making the force that wins this battle to be the force of gravity.

When the force of gravity wins, the star collapses on itself and from here, depending on the star's mass, several things can happen, such as the star becoming a white dwarf, a supernova, even a black hole.

Explanation:

Answer: 490N

Explanation:

Newton is the unit for force. Force = mass x acceleration

F=N m=50kg a=9.8 (earth's acceleration of gravity)

F=50X9.8

F≈490N

The magnitude of the force of air resistance, in newtons, on a 55-kg skydiver assuming the force of air resistance is constant can be found using the following formula:

Fr = ma fr = Force of air resistance m = ma a = acceleration

In this case, the acceleration is the acceleration due to gravity which is 9.8 m/s².

To determine the acceleration in this case, we can use the following formula:

Vf² = Vi² + 2aswhere:Vf = final velocity (maximum speed)Vi = initial velocity (0 m/s)s = displacement (height)

Therefore,51² = 0² + 2(9.8)s490 = 9.8s

Simplifying490/9.8 = s50 = sSo the displacement of the skydiver is 50 m.

Thus, the acceleration is calculated as follows:

a = Δv/ΔtwhereΔv = 51 m/s - 0 m/s = 51 m/sΔt = time taken to fall 50 m using the acceleration due to gravity which is 9.8 m/s²Δt = √(2s/a)Δt = √(2(50)/9.8)Δt = 3.18 s So, a = Δv/Δta = 51/3.18a = 16 m/s²

To determine the force of air resistance, we can use the formula Fr = ma Fr = (55)(16)Fr = 880 N

Therefore, the magnitude of the force of air resistance, in newtons, on the skydiver is 880 N.

If a plot of velocity vs. time has a negative slope, then the acceleration of the system is non-zero and in the opposite direction to the velocity. This negative acceleration can result from forces acting on the system that oppose its motion or from the system losing energy due to friction or other factors.

Velocity is the rate of change of displacement with respect to time. If the velocity vs. time graph has a negative slope, it means that the velocity is decreasing over time. In other words, the object is slowing down. Since acceleration is the rate of change of velocity with respect to time, a negative slope indicates that the acceleration is non-zero and acts in the opposite direction to the velocity.

If the velocity is decreasing, it means that the object is experiencing a deceleration or negative acceleration. This negative acceleration can result from forces acting on the system that oppose its motion or from the system losing energy due to friction or other factors.

Arsenic

Explanation:

Arsenic is in group 5 and period 4. Group numbers tell us the number of valence electron and period number tells us the number of shells in an element.

The time dependence of the velocity components of an object moving like the ride's seats are:

vx(t) = -rω sin(ωt)

vy(t) = rω cos(ωt)

And the time dependence of the acceleration components of the object are:

ax(t) = -rω^2 cos(ωt)

ay(t) = -rω^2 sin(ωt)

To calculate the time dependence of the velocity components of an object moving like a ride's seats, we need to know the equation of motion for the object. Let's assume that the ride's seats move in a circular path with a constant angular velocity, ω, and a radius, r.

Then, the position vector of the object can be written as:

r(t) = r cos(ωt) i + r sin(ωt) j

where i and j are the unit vectors in the x and y directions, respectively.

To find the velocity vector, we can take the derivative of the position vector with respect to time:

v(t) = dr/dt = -rω sin(ωt) i + rω cos(ωt) j

The x-component of the velocity is -rω sin(ωt) and the y-component is rω cos(ωt).

To find the acceleration vector, we can take the derivative of the velocity vector with respect to time:

a(t) = dv/dt = -rω^2 cos(ωt) i - rω^2 sin(ωt) j

The x-component of the acceleration is -rω^2 cos(ωt) and the y-component is -rω^2 sin(ωt).

So, the time dependence of the velocity components of the object moving like the ride's seats are:

vx(t) = -rω sin(ωt)

vy(t) = rω cos(ωt)

And the time dependence of the acceleration components of the object are:

ax(t) = -rω^2 cos(ωt)

ay(t) = -rω^2 sin(ωt)

Note that the magnitude of the acceleration vector is constant and equal to rω^2.
