The Impulse of 120 Ns was given to the puck by hitting at 1200N for 0.1 s of contact.
Impulse is the integral of force or we can say force over the time interval. In this case of hockey puck force provided is 1200n, for the time span of 0.1 seconds contacts. And Impulse is also called a change in momentum. That is dp(Delta p). So force and time of contact both are directly proportional to impulse.
so dp = fxdt............(dt- delta t or change in time)....(i)
dp = 1200x0.1 ........... from (i)dp= 120Here the impulse is calculated as 120-newton seconds on hitting the ball by 1200 N and in contact time of 0.1 s.

But the Unionville, Maryland report of 1.23" in one minute on July 4, 1956 was found to be true after the U.S. Weather Bureau conducted numerous in-depth analyses of the claim (see for the Monthly Weather Review summary). a rainfall gauge that records: To perform the measurement, a Friez Universal Type with a 12-inch capacity, a dual traverse pen, and a 24-hour clock gear on a chart drum was employed. It measured a storm total of 3.60" between 2:50 p.m. and 11:30 p.m., with 2.84" of that total falling in a 50-minute span between 2:50 and 3:40 p.m. The exposure was good, and the storm total was 3.60" overall. It was between 3:22 and 3:23 p.m. when the apparent 1.23" total was taken. To establish the gauge's accuracy and calibration, a variety of tests were performed on it. All of the tests that were run on the gauge found it to be reliable. The record's certification included consideration of anecdotal data as well.

Power is said to be the rate of completion of work. The average power for the first and second cases will be 1166.7 watts and 2000 watts, respectively.
Power explanation?
Power is a term used to describe how quickly work is completed. The SI unit it uses is the watt. Another way to measure power is in terms of horsepower. Mathematically, it can be calculated by dividing the overall work done by the overall time the body spent doing it.The average sprinting power of a human is as follows:Power equals E/t.P = 1/2mv² - 0/ΔtP = 1/2(70)(10)² - 0/3P = 1166.7 WattThe average power of the greyhound is listed as,P = 1/2mv²- 0/ΔtP = 1/2(30)(20)² - 0/3P = 2000Watt.

Astronauts on the first trip to mars take along a pendulum that has a period on earth of 1.50 s. the period on the other planet turns out to be 2.45 s. what is the free-fall acceleration on that other planet?
On Mars, the rate of free fall acceleration is 3.68 m/s².
A simple L-length pendulum's period T can be calculated using,
T = 2π[tex]\sqrt{\frac{L}{g} }[/tex]
where g stands for gravity's acceleration.
A pendulum's period on Earth is, T = 2π[tex]\sqrt{\frac{L}{g} }[/tex]... (1)
The pendulum's period on Mars is, T' = 2π[tex]\sqrt{\frac{L}{g'} }[/tex]... (2)
It is given that T = 1.50 s and T' = 2.45 s.
Eq. (1) divided by Eq. (2) results in:
[tex]\frac{T}{T'} =[/tex] [tex]\frac{2\pi \sqrt{\frac{L}{g} } }{2\pi \sqrt{\frac{L}{g'} } }[/tex]
or, [tex]\frac{T}{T'} = \sqrt{\frac{g'}{g} }[/tex]
or, [tex]g' = \frac{T^{2} }{T'^{2} } g[/tex]
We have, g = 9.8 m/s²
So, putting all the values in above equation, we get
g' = [tex]\frac{1.50^{2} }{2.45^{2} }[/tex] × 9.8

how far must a 2.0-cm-diameter piston be pushed down into one cylinder of a hydraulic lift to raise an 9-cm-diameter piston by 35 cm?
The small piston must be pushed down into one cylinder of the hydraulic lift 1.71 cm to raise the 9-cm-diameter piston by 35 cm.
In a hydraulic lift, the force applied on the smaller piston is transmitted to the larger piston through a fluid, usually oil, in a closed system. The ratio of the areas of the two pistons is equal to the ratio of the forces applied to them.
The area of the smaller piston is:
A_small = (πr^2) = (π(2cm/2)^2) = (π*2^2 cm^2) = 4π cm^2
The area of the larger piston is:
A_large = (πr^2) = (π(9cm/2)^2) = (π*9^2 cm^2) = 81π cm^2
According to the principle of a hydraulic lift, the ratio of the forces applied to the two pistons is equal to the ratio of their areas.
F_large / F_small = A_large / A_small
So if we know the force on the small piston and the distance it moves, we can find the distance the large piston must move to lift the same weight.
F_small = m*g
Where m is the weight of the object to be lifted and g is the acceleration due to gravity.
F_small = (m/A_small) * A_large
then we can find the distance the large piston must move to lift the same weight:
distance_large = (F_small * distance_small) / F_large
Given, the small piston's diameter is 2 cm, the large piston's diameter is 9 cm, and the large piston's distance to lift is 35 cm
A_small = 4π cm^2
A_large = 81π cm^2
distance_small = 2cm
distance_large = 35cm
So the distance the small piston must be pushed down into one cylinder of the hydraulic lift to raise the 9-cm-diameter piston by 35 cm is:
distance_small = (35*4π) / 81π = (140/81) cm = 1.71 cm
So the small piston must be pushed down into one cylinder of the hydraulic lift 1.71 cm to raise the 9-cm-diameter piston by 35 cm.

The y -component of the electric field of an electromagnetic wave traveling in the x direction through vacuum obeys the equation ey=(375n/c)cos[kx−(2.20×1014rad/s)t] . ( c=3.0×108m/s ) what is the largest that the x -component of the wave can be?
The largest that the x-component of the wave can be is zero.
As the electromagnetic wave is traveling in the x direction and the y-component of the electric field is given, it means that there is no x-component of the electric field.
An electromagnetic wave is a transverse wave, which means that the oscillations of the electric and magnetic fields are perpendicular to the direction of propagation of the wave.
ln this case, the wave is traveling in the x direction, and the equation for the y-component of the electric field is given.
This means that the oscillations of the electric field are in the y direction and not in the x direction.
Therefore, it can be inferred that there is no x-component of the electric field in this wave. Since the x-component of the electric field is zero, it means that the largest that it can be is zero.

The position at which the pendulum have the greatest kinetic energy and the greatest potential energy is at the bottom and the top position, respectively.
A pendulum is a weight suspended from a pivot point, it swings back and forth under the influence of gravity. The position of the pendulum where the weight is at the lowest point is called the bottom position, and the position where the weight is at the highest point is called the top position.
At the bottom position, the pendulum has the greatest kinetic energy and the least potential energy. At this point, the weight is moving at its fastest, and the gravitational potential energy is at a minimum.
At the top position, the pendulum has the greatest potential energy and the least kinetic energy. At this point, the weight is moving at its slowest and the gravitational potential energy is at a maximum.

Kinetic energy of a car traveling at 17 m/s is 49,823 J. The speed of the shopping cart moving at a distance of 39 m is 23.37 m/s.
How to calculate kinetic energy and speed?The kinetic energy of the car can be calculated using the formula KE = (1/2)mv², where m is the mass of the object (in this case, the car) and v is the velocity. Substituting the given values, we get KE = (1/2)(219 kg)(17 m/s)² = 49,823 J.
The final velocity of the shopping cart can be calculated using the equation of work-energy principle, which states that the work done on an object is equal to its change in kinetic energy, W = Fd, where F is the force applied (35 N) and d is the distance over which it is applied (39 m).
Therefore, W = 35 N x 39 m = 1365 J.
To find final velocity, we will use the formula, final kinetic energy = 1/2mv², where m is the mass of the object (5kg) and v is the final velocity.
Substituting the given values, 1365 = 1/25v² so v = √(1365 x 2/5) = √(546) m/s = 23.37 m/s.

kinetic energy of the rolling ball of velocity of 7 m/s is given 28 Joules. Then, the mass of the rolling ball is 1.14 kg.
What is kinetic energy?The kinetic energy of an object is the energy generated by virtue of its motion. It is related to its mass and velocity by the expression written below:
Ke = 1/2 m v²
Thus, kinetic energy increases with mas and velocity. When a body starts moving from rest, its potential energy starts to convert into kinetic energy.
Given the velocity of the rolling ball = 30 m/s
let m be the mass of the rolling ball.
then Ke = 1/2 × m kg ×7 m/s × 7 m/s = 28 J.
Then mass m = 2 Ke/v²
m = 2 × 28 J/(7 m/s)²

the only thing affecting the object is gravity so it is in free fall.
since the ball is in the air no other forces are affecting it other than gravity so the only acceleration is gravity
objects in the air tend to curve up because of the force that the hand exerts on the ball and then down because of gravity and hit the floor, forming a parabola
therefor all are true
