Two air craft P and Q are flying at the same speed 300m/s. The direction along which P is flying is at right angles to the direction along which Q is flying. Find the magnitude of velocity of the air craft P relative to air craft Q
Answer:
424.26 m/s
Explanation:
Given that Two air craft P and Q are flying at the same speed 300m/s. The direction along which P is flying is at right angles to the direction along which Q is flying. Find the magnitude of velocity of the air craft P relative to air craft Q
The relative speed will be calculated by using pythagorean theorem
Relative speed = sqrt(300^2 + 300^2)
Relative speed = sqrt( 180000 )
Relative speed = 424.26 m/s
Therefore, the magnitude of velocity of the air craft P relative to air craft Q is 424.26 m/s
Standing and holding a barbell that has a mass of 100kg at a height of 2m involves being done on the barbell to maintain
the position.
Answer:
1960Joules
Explanation:
Since we are not told what too find, we can as well find the Gravitational Potential Energy.
GPE = mass * acceleration due to gravity * height
GPE = 100*9.8 * 2
GPE = 980*2
GPE = 1960Joules
Hence the gravitational potential Energy is 1960Joules
When an object is moving to the left and slowing down, what direction is the acceleration?
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

The primary relationship between the two is their ability to transform into each other. In other words, potential energytransforms into kinetic energy, andkinetic energy converts into potential energy, and then back again.
A circus performer wants to land in a net 5 meters to the right of where she will let go of the trapeze. If she is 10 meters above the net, how fast must she be moving horizontally when she lets go? Round your final answer to three significant figures.
Answer:
Assuming no air friction,
the time it takes to fall 10 m = t = √2h/g = √(20/9.8) = 1.43 s
horizontal distance = 5 m
horizontal speed = distance/time = 5/1.43 = 3.5 m/s ANS

A student has two identical sheets of paper. He crumples one up into a small ball. If he drops the sheet of paper and the ball of paper off a building at the same time, which of the following statements describes the result?
A. The sheet of paper because it is more affected by gravity.
B. The ball of paper hits the ground first because it is more affected by gravity
C. The sheet of paper and the ball of paper hit the ground at the same time.
D. The ball of paper hits the ground first because it has less surface area.
Answer:
B
Explanation:
basically, because the ball "weighs" more now, it will hit the ground quicker. so technically gravity is more affective towards it. the piece of paper kind of floats it's way down. gravity isn't pushing on one force more, but because because the ball weighs more, it technically would be said so. hope this helps!

The range of human hearing is 20 Hz – 20 000 Hz.
Calculate the longest and shortest wavelengths we can hear.
Explanation:
the velocity of sound in air is 330m/s
and v=fh, where h is wavelength f is frequency,
h=v/f.......(1)
longer wavelength
h=330/20,h=16.5m
shorter wavelength
h=330/20000,h=1.65x10-²m
The lesser frequency was used for finding the longer wavelength since wavelength is inversely proportional to frequency,
thus an increase in frequency brings a decrease in wavelength.
and shorter wavelengths are more high and intense

A piano tuner hears a beat frequency when using a tuning fork to tune a piano wire. The piano tuner should adjust the tension in the wire to
increase the amount of interference and increase the beat frequency.
increase the amount of interference and decrease the beat frequency.
decrease the amount of interference and decrease the beat frequency.
decrease the amount of interference and increase the beat frequency.
Answer:
There is only a beat frequency when the frequency heard (perhaps a tuning fork) is different from the frequency from the object in question (piano string, etc.).
The beat frequency equals the difference of the frequencies of the sources.
The piano tuner should adjust the tension in the wire to: C. decrease the amount of interference and decrease the beat frequency.
A wave can be defined as a disturbance created in a medium, which progressively transports energy from a source to another location without the transportation of matter.
Basically, some of the phenomenon and properties associated with waves include the following:
Doppler shift (Doppler effect)ReflectionRefractionDiffractionInterferenceAn interference refers to a phenomenon in which two (2) waves meet while traveling along the same medium and they superpose to produce a resultant wave with either a lower, greater, or the same amplitude.
In this scenario, a beat frequency is being heard by a piano tuner when using a tuning fork to tune a piano wire. Thus, the piano tuner should adjust the tension in the wire, so as to decrease the amount of interference and the beat frequency.

What's Inertia ????☁️☁️
Explanation:
the inability to change the position from rest to motion or motion to rest by themselves is inertia.
Answer:
Inertia is the property of a body in rest to resist motion or a body in motion to continue to its state of motion unless acted by external forces.
Two beakers are at the same temperature. One beaker has more water than the other. Which one contains more heat? Explain why.
Answer:
I would say the beaker with less water.
Explanation:
I was say this because while they are the same temperature the beaker with more water still has to fluctuate the heat or cold. They do this at the same speed but since there is less water in one beaker it finishes faster where as the beaker with more water will finish later.
If a 96 n force of gravity is happening to a falling basketball what is the ball mass? The accelydue to gravity is 9.8m/s^2
Answer:
9.80 kg
Explanation:
F = ma
96 N = m(9.8 m/s^2)
m = 9.80 kg
The mass of the ball will be m= 9.8 kg
What is Newton's second law of motion?
It states that the force is equal to the rate of change of momentum . For a constant mass , force is equal to mass times acceleration
given :
Force due to gravity = 96 N
g = acceleration due to gravity = 9.8 m /s^2
using Newton's second law of motion
Since , F = ma
96 = m g
m = 96/9.8
m= 9.8 kg
The mass of the ball will be m= 9.8 kg

2.A motorcycle’s velocity at the top of the hill is 11.0 m/s. 4.0 seconds later it reaches the bottom of the hill with a velocity of 20.0 m/s. What is the acceleration of the motorcycle?
Answer:
1) as far as I remember
Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time
So we would use this formula a=vf-vi/t
So 20-11/4

Explanation:
How are amplitude, intensity, and
loudness related?
Answer:
Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.

What is the law of inertia? Give an example of inertia in action.
Answer:
The law of inertia is another name for Newton's first law. Newton's first law states that an object will not change its motion or direction unless a force acts on it. An object at rest will stay at rest and an object in motion will stay in motion if there isn't any force acting on them.
Example: When a car uses its brakes to stop, you sometimes feel like you are sliding forward. That is because the inertia keeps you moving forward, even though the car stopped.
Explanation:
Answer:
Law of inertia is sometimes called Newtons First law of motion.
Newtons first law of motion states that"A body will continue to its state of rest or motion unless external force acted upon it.

A small pebble and one large boulder start at the same height and begin rolling down the side of a mountain. Which object would have less kinetic energy as it crashes on the road at the bottom of the mountain? Justify your selection.
Answer:
The small pebble
Explanation:
Since the potential energy, P.E lost equals kinetic energy, K.E gained,
P.E = K.E
P.E = mgh = K.E
So, K.E = mgh where g = acceleration due to gravity and h = height of drop
Since h and g are constant
K.E ∝ m
So, the kinetic energy of the object is directly proportional to its mass. Thus, the object with the smaller mass has the lesser kinetic energy.
Since the object with the smaller mass is the small pebble, so the small pebble would have less kinetic energy as it crashes on the road at the bottom of the mountain.
