The angle above the horizontal of the motion of mass A + B after the collision. as well as others are mathematically given as

According to the collision hypothesis of chemistry, chemical reactions happen when two molecules or atoms collide.

Generally, the equation for Collison equilibrium is  mathematically given as

For horizontal motion

mvAx+m2vAx = 2mvfx

For vertical motion

-mvAy+m2vAy = 2mvfy

vfy = 1/2 vAy

\(\tan \theta f = vfy/vfx \\\\\tan \theta f = 1/3 vAy/vAx \\\\\tan \theta f = vAy/vAx \\\\\theta f = tan-1 ( 1/3 tan (56) )\\\\\)

\(\theta f = 26.3 \deg\)

(b)

\(v fy = vf sin \theta f\\\\vAy = vA sin theta i\\\\vf/vA = vfy/vAy sin( \theta i)/sin(\theta f)\\\\vf/vA = 1/2 sin(56)/sin(26.3) \\\\\)

vf/vA= 0.94

Answer:

Upward: Negative

Downward: Positve

Explanation:

Let upward be positive

We want to find the work done on the object upwards.

The equation of work done due to gravity is

\(f _{g}d \cos( \alpha ) \)

It is read as force of gravity times displacement times cos of the angle between the force and displacement.

Since gravity is happening down of the center of mass and the displacement is upwards, the angle is 180° so

\(f_{g}d \cos(180) \)

Cosine of 180 is -1

so

\( - f_{g}d \)

If we go downwards, the sign will be positive because cos(0)=1

The input to the power station is 5x10^9 W. This means that the power station requires an input of 5x10^9 watts to produce an electrical power output of 1.9x10^9 watts with an efficiency of 38%.

The efficiency of a power station is defined as the ratio of its output power to input power. Therefore, we can use the efficiency and the electrical power output of the power station to calculate its input power as follows:

Efficiency = Output power / Input power

Solving for input power, we get:

Input power = Output power / Efficiency

Substituting the given values, we get:

Input power = 1.9x10^9 W / 0.38

Input power = 5x10^9 W (to two significant figures)

The rest of the input power is lost as heat due to inefficiencies in the power generation process.

ANSWER:

Sound waves are faster in water

STEP-BY-STEP EXPLANATION:

Sound travels differently in water than it does in air.

Sound waves travel faster in denser substances because neighboring particles will more easily collide with each other.

Water is denser than air, which means that sound waves travel much faster in water than in air.

Although they travel faster in water, we must keep in mind that the human ear evolved to hear sounds in the air and is not as useful when submerged in water.

The acceleration of Thomas is 0.233 m/s^2.

Acceleration is the rate of change of velocity. Thomas the Train chugs along at a velocity of 2 m/s.

Thomas needs to go faster so more coal is shoveled into his engine and he accelerates for 10 seconds until he is going 4.33 m/s.

We are to find the acceleration of Thomas.

The formula for acceleration is given as :

acceleration = (final velocity - initial velocity) / time

In the given problem, the initial velocity of Thomas, u = 2 m/s.

The final velocity of Thomas, v = 4.33 m/s The time for which Thomas accelerates, t = 10 s.

Therefore, the acceleration of Thomas will be given as:

a = (v - u) / ta = (4.33 - 2) / 10s => 2.33 / 10s => 0.233 m/s^2

Thus, the acceleration of Thomas is 0.233 m/s^2.

To summarize, the acceleration of Thomas is 0.233 m/s^2.

Answer:

A. The rays can change molecules and atoms in the body into ions.

If the thrust was cut in half, the new acceleration of the spare shuttle would be half of its original acceleration.

Assuming that the mass of the space shuttle remains constant, the new acceleration of the space shuttle would be half of its original acceleration.

The formula for acceleration is:

a = F/m

where,

a = acceleration

F = force applied

m = mass of the object

If the force is cut in half, the new acceleration can be calculated as follows:

a' = (F/2)/m

where,

a' = new acceleration

Simplifying this equation, we get:

a' = F/2m

Since we know that a = F/m, we can substitute this expression into the equation above to obtain:

a' = a/2

Kiran's average speed from Tortula to Cactus was 58.78 miles per hour.

Let's use "x" miles per hour as Kiran's speed from Tortula to Cactus.

The time it takes Kiran to traverse the 250 miles between Tortula and Cactus is calculated as follows: time = distance / speed time = 250 / x

We also know that she upped her speed by 10 miles per hour throughout the 360-mile distance from Cactus to Dry Junction.

For that portion of the journey, let's designate her new speed "x+10" mi/h.

Her trip time is calculated as follows: time = distance / speed

time = 360 / (x+10)

Given that the entire journey lasted 11 hours, we can construct the following equation:

Time from Dry Junction to Cactus plus the time from Cactus to Tortula equals 11

250/x + 360/(x+10) = 11

We can now determine x:

250(x+10) + 360x = 11x(x+10)

0 - 400 - 2500 = 250x + 2500 + 360x = 11x2 + 110x

The quadratic equation is as follows: x = [400 sqrt(4002 - 4(11)(-2500))]

/ (2(11)) x = [400 ± sqrt(176000)]

/ 22

Speed cannot be negative, so we can disregard the negative result. Therefore, x = [400 + sqrt(176000)]

/ 22\sx ≈ 58.78

Kiran travelled between Tortula and Cactus at a speed of almost 58.78 miles per hour.

To calculate the total distance, we add the distances traveled in each leg of the journey: 60 kilometers (from A to B) + 45 kilometers (from B back to A) = 105 kilometers.

However, displacement refers to the change in position of an object in a straight line from its starting point to its ending point. In this case, since the boat starts and ends at the same point (A), the total displacement is zero.

49. To find the length of a pendulum that has a period of 2.3 seconds on the Moon, where the gravitational acceleration (g) is 1.6 N/kg, we can use the formula:

Period (T) = 2π√(Length (L) / g)

Substituting the given values:

2.3 = 2π√(L / 1.6)

To solve for L, we can rearrange the formula:

L = (2.3 / (2π))^2 * 1.6

L ≈ 0.781 meters (or 78.1 centimeters)

So, the pendulum must be approximately 0.781 meters (or 78.1 centimeters) long to have a period of 2.3 seconds on the Moon.

(a)  the horizontal distance between the saddle and limb when the man makes his move is approximately 11.386 meters.

(b)  the man is in the air for approximately 0.843 seconds.

To determine the horizontal distance between the saddle and limb when the man makes his move, we need to consider the horizontal velocity of the man when he drops from the tree limb.

Given:

Speed of the horse (constant velocity), v = 13.5 m/s

Vertical distance between the limb and saddle, h = 3.55 m

a) To find the horizontal distance, we can use the formula:

horizontal distance = horizontal velocity × time

Since the man drops vertically, his initial horizontal velocity is zero. The only horizontal velocity he will have is due to the motion of the horse.

The time taken by the man to fall can be determined using the equation for free fall:

h = (1/2) × g × t²

Where g is the acceleration due to gravity (approximately 9.8 m/s²) and t is the time.

Rearranging the equation, we get:

t = √(2h / g)

Substituting the given values:

t = √(2 × 3.55 / 9.8) ≈ 0.843 s

Now, we can find the horizontal distance:

horizontal distance = v × t

horizontal distance = 13.5 × 0.843 ≈ 11.386 m

Therefore, the horizontal distance between the saddle and limb when the man makes his move is approximately 11.386 meters.

b) The time the man is in the air can be calculated using the same equation for free fall:

t = √(2h / g)

Substituting the given value of h:

t = √(2 × 3.55 / 9.8) ≈ 0.843 s

Thus, the man is in the air for approximately 0.843 seconds.
