<u>Answer
</u>
4.The objects have the same acceleration
<u>Explanation
</u>
Acceleration due to gravity is the acceleration acquired by an object when falling freely.
Under normal conditions, different objects has different accelerations depending on their mass and surface area. This is brought about by the air resistance they experience as they fall.
The case is difference when they the experiment is carried out in a controlled condition. That is in vacuum. I this case the acceleration of the objects is the same.
From solid to liquid. also known as melting
from solid to gas known as sublimation
The frequency of the wave is 0.5Hertz
<h3>How to calculate the
frequency of a wave</h3>
The formula for calculating the velocity of a wave is expressed as:
velocity = frequency * wavelength
Determine the formula for the frequency
frequency = velocity/wavelength
Given the following parameters
Velocity = 1.00 m/s
wavelength = 2.00m
Determine the frequency
f = 1.00/2.00
f = 0.5Hz
Hence the frequency of the wave is 0.5Hertz

Answer:
t= 25.04 s
Explanation:
Given that
Initial angular speed ,ωi= 26 rad/s
Angular acceleration ,α=0.43 rad/s²
We know that kinetic energy of the wheel given as
I=Mass monent of inertia
ω=Angular speed
If kinetic energy is two time then the final angular speed
We know that
t= 25.04 s
After 25.04 s then kinetic energy will become two times of the initial kinetic energy.
Answer:
300 J (Joules)
A Joule will measure "the amount of work done when a force of one newton is exerted through a distance of one meter"
