Answer:

0N

Explanation:

When you draw a free body diagram, You have a 7N arrow pointing left, and a 3N arrow pointing right. When you subtract the two, you still have a force of 4N on the left. However, seeing as how gravity is in play at a force of 4N, the two forces cancel out and you get 0N.

To determine which situation will produce the greatest change of momentum for a 1.0-kilogram cart, we need to compare the magnitudes of the impulse in each situation. Impulse is defined as the change in momentum of an object and is equal to the force applied multiplied by the time interval over which the force acts.

Impulse = Force * Time, the impulse for each situation:

1) Impulse = (Force) * (Time) = (5 N) * (2 s) = 10 N·s

2) Impulse = (Force) * (Time) = (10 N) * (0.5 s) = 5 N·s

3) In this situation, we need to calculate the initial momentum (p_initial) and final momentum (p_final) to find the change in momentum.

Initial momentum (p_initial) = mass * initial velocity = 1.0 kg * 0 m/s = 0 kg·m/s

Final momentum (p_final) = mass * final velocity = 1.0 kg * 3 m/s = 3 kg·m/s

Change in momentum = Final momentum - Initial momentum = 3 kg·m/s - 0 kg·m/s = 3 kg·m/s

4) In this situation, we again calculate the initial momentum (p_initial) and final momentum (p_final) to find the change in momentum.

Initial momentum (p_initial) = mass * initial velocity = 1.0 kg * 2 m/s = 2 kg·m/s

Final momentum (p_final) = mass * final velocity = 1.0 kg * 4 m/s = 4 kg·m/s

Change in momentum = Final momentum - Initial momentum = 4 kg·m/s - 2 kg·m/s = 2 kg·m/s.

The situation that will produce the greatest change in momentum for the 1.0-kilogram cart is situation 1, where a net force of 5 N is applied for 2 seconds, resulting in an impulse of 10 N·s.

Explanation:

The child who will sink to the ground is the one who exerts the greatest pressure on the ground, even though the force, which in this case is equal to the weight, is equal.

Pressure is defined by

           P = F / A

in this case the strength of the children is their weight

Explanation:

The initial speed of the clay target can be determined using the principles of projectile motion. To begin, let's consider the vertical motion of the clay target.

At the maximum height, the vertical velocity of the target is zero since it momentarily stops before falling back down. We can use the equation for vertical motion:

v_f²  = v_i²  + 2 * a * d

where v_f is the final vertical velocity (zero in this case), v_i is the initial vertical velocity, a is the acceleration due to gravity (-9.8 m/s² ), and d is the vertical displacement (4.6 m).

Plugging in the known values, we get:

0 = v_i²  + 2 * (-9.8 m/s² ) * 4.6 m

Simplifying the equation, we have: v_i² = 2 * 9.8 m/s²  * 4.6 m v_i²  = 89.68 m² /s²

Taking the square root of both sides, we find:

v_i = √(89.68 m² /s² ) = 9.46 m/s Now, let's consider the horizontal motion of the clay target. The horizontal velocity remains constant throughout the motion, so we can use the equation:

v_x = v_i * cosθ

where v_x is the horizontal velocity, v_i is the initial velocity, and θ is the launch angle (35°).

Plugging in the known values, we get: v_x = 9.46 m/s * cos(35°) Calculating this, we find: v_x = 9.46 m/s * 0.819 = 7.75 m/s Therefore, the initial speed of the clay target when it is launched is approximately 7.75 m/s.

The time required for the bacteria concentration to be reduced to 15ppm using the Newton's method is 8.12 hours.

Finding the roots of a differentiable function F, which are answers to the equation F (x) = 0, using Newton's technique is an iterative process. To solve this problem, we can use Newton’s method with an initial guess of t=6 and a stopping criterion of 1% (tol=0.01). The formula for Newton’s method is:

xₙ₊₁ = xₙ - f(xₙ)/f'(xₙ)

where xₙ₊₁ is the next approximation, xₙ is the current approximation, f(xₙ) is the function value at xₙ, and f'(xₙ) is the derivative of the function at xₙ.

For this problem, we have:

f(t) = 77 \(e^{-1.5 t}\) +20 \(e^{-0.08 t}\) - 15

f’(t) = -115.5 \(e^{-1.5 t}\) - 1.6 \(e^{-0.08 t}\)

The component of the crate's weight that is parallel to the ramp is the only force that acts in the direction of the crate's displacement. This component has a magnitude of

F = mg sin(20.0°) = (15.0 kg) (9.81 m/s^2) sin(20.0°) ≈ 50.3 N

Then the work done by this force on the crate as it slides down the ramp is

W = F d = (50.3 N) (2.0 m) ≈ 101 J

The work-energy theorem says that the total work done on the crate is equal to the change in its kinetic energy. Since it starts at rest, its initial kinetic energy is 0, so

Modeling Earth’s Tilt

When watching the stars at night, they do appear to move very slowly. This is because the Earth is constantly moving. The Earth completes one “rotation” every twenty-four hours. A rotation is when the planet spins around once. The Earth rotates counterclockwise; this is why the Sun “rises” in the East and “sets” in the West. It is not the Sun’s movement that causes days, but rather the Earth turning around in front of the Sun. The Earth’s axis (the point at which it rotates around, for example, if you were to spin around while standing in one spot, your axis would be an imaginary line running through your head straight down to your feet) is in line with a star named “Polaris”. Polaris is also known as the “North Star” since it is directly above the Earth’s axis. Since this star is directly above the Earth’s axis, it does not appear to move, however, the rest of the stars in the sky move around Polaris (for example: when you spin around, the object directly above your head does not appear to move but everything else seems to spin around that object). Polaris is only seen in the Northern hemisphere and it belongs to the Little Dipper constellation (it’s the last star at the end of the “handle”). Another type of motion is known as “revolution”. Revolution is when one object completes a circular path around another object. The Earth takes 365.24 days to revolve around the Sun. This is why a year is 365 days long. During the year the Earth is angled differently towards the Sun. These changing angles provide us with different Sun intensities and therefore we get four different seasons. Since the Earth is at different positions in space over the year, we see different constellations throughout the year

Explanation:

:)

Factors That Affect Climate Project: Modeling Earth’s Tilt is explained below.

The rotation is the spinning around of an object about its own axis passing through the center.

When the Earth rotates about its own axis, the rotation completes in 24 hours. This causes the day to night and night to day. When the part of Earth is in front of Sun, there is day. But, when the same part of Earth goes away from the Sun, the sunset occurs and then eventually night occurs.

While watching the stars around evening time, they really do seem to move gradually. This is on the grounds that the Earth is continually moving. The Earth finishes one day in each 24 hours. A turn is the point at which the planet twirls around once. The Earth pivots counterclockwise. Not the Sun's development causes days, yet rather the Earth pivoting before the Sun.

The Earth's pivot is in accordance with a star named Polaris. Polaris is otherwise called the North Star since it is straight over the Earth's pivot. Since this star is straight over the Earth's pivot, it doesn't seem to move, nonetheless, the other stars overhead move around Polaris . Polaris is just found in the Northern half of the globe and it has a place with the Little Dipper heavenly body. One more sort of movement is known as "upheaval".

Upheaval is the point at which one item finishes a roundabout way around another item. The Earth requires 365.24 days to rotate around the Sun. To this end, a year is 365 days in length. During the year the Earth is calculated contrastingly towards the Sun. These changing points furnish us with various Sun forces and thusly we get four unique seasons. Since the Earth is at various situations in space over the course of the year, we see various groups of stars consistently.

Thus, the paragraph about how the climate affects the Earth and its tilt is explained above.

The minimum power must the motor deliver to lift the fully loaded elevator at a constant speed 2. 10 m/s is 19.1 kW.

Speed is the rate an object or person is moving in a given direction. It is measured as distance (meters, feet, miles, etc.) per unit of time (seconds, minutes, hours, etc.). It is an important and fundamental characteristic of matter, as it determines the kinetic energy of an object. Speed is also a vector quantity, as it describes both magnitude and direction. Speed has general and special relativity implications as well, as relative motion affects the propagation of light and space-time.

Step 1: Calculate the net force on the elevator:

Fnet = Ffr – mg

Fnet = 4.0 x 103 N – (2.5 x 103 kg)(9.81 m/s²)

Fnet = 9.10 x 103 N

The bowling ball would have to spin at approximately 10.07 rpm to have an angular momentum of 0.24 \(kgm^2/s\).

The angular momentum (L) of an object is given by the formula:

L = I x ω

where I is the moment of inertia of the object and

ω is its angular velocity.

The moment of inertia (I) of a solid sphere is given by:

I = (2/5) x m x \(r^2\)

where m is the mass of the sphere and r is its radius.

Substituting the given values, we have:

m = 5.8 kg

r = 0.17 m

So, the moment of inertia of the bowling ball is:

I = (2/5) x 5.8 kg x \((0.17 m)^2\) = 0.227 kg \(m^2\)

Now, we can rearrange the first formula to solve for ω:

ω = L / I

Substituting the given value of L, we get:

ω = 0.24 \(kgm^2\)/s / 0.227 \(kgm^2\) = 1.057 rad/s

Finally, we can convert the angular velocity from radians per second to revolutions per minute (rpm):

1 rad/s = 60/(2π) rpm ≈ 9.549 rpm

So, the bowling ball would have to spin at approximately:

ω = 1.057 rad/s x 60/(2π) ≈ 10.07 rpm

A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time.

Here are some common patterns  and interpretations of the v vs t graph:

Zero Velocity: If the graph intersects the x-axis (velocity = 0) at a particular time, it indicates that the object is momentarily at rest during that time.

Constant Velocity: A straight horizontal line in the graph suggests that the object maintains a constant velocity. The slope of this line represents the magnitude and direction of the constant velocity.

Changing Velocity: A sloping line indicates that the object's velocity is changing. The slope of the line represents the acceleration of the object. A steeper slope indicates a higher acceleration.

Positive and Negative Velocity: If the graph is above the x-axis, it indicates positive velocity (moving in the positive direction), while being below the x-axis indicates negative velocity (moving in the negative direction).

Curved Graph: A curved graph suggests that the velocity is changing non-uniformly. The curvature indicates the object's acceleration is not constant.

According to the graph given, we can directly see the answers to the following questions:

a). initial velocity of the particle V₀: v =  0.5   0 m/s

b). total distance Δx raveled by the particle: Δx =  75   m

c). average acceleration of the particle over the first 20.0 seconds:

In this graph, time is plotted on the horizontal axis and velocity on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straight-line motion, however, these vectors have only a single nonzero component in the direction of motion. Thus, in this problem, we will call the velocity and the acceleration, even though they are really the components of the velocity and acceleration vectors in the direction of motion, respectively.

c). What is the average acceleration \(a_{av\) of the particle over the first 20.0 seconds?

d). What is the instantaneous acceleration of the particle at t = 45.0 s?

Answer:The answer is option C, the point A

Explanation:Just did it

c. A  is the correct answer.

It is the acceleration of a body traversing a circular path. Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration.

According to the question.

In the picture , a person swinging a toy plane attached to a string in uniform circular motion.

The direction of velocity is perpendicular to the direction of the position and tangent to the circular orbit.

When an object moves in a circular orbit, the direction of the velocity changes and the speed may change as well.

Direction of velocity is constantly changing.

The tangent at any point gives the direction of velocity at that point, where as acceleration is always directed towards the recent in a uniform circular motion.
