<u>Answer: </u>Chemical energy, electrical energy, and Mechanical energy (Kinetic energy).
<u>Explanation:</u>
When Simon puts new batteries in his radio controlled car and its controller, the<u> chemical energy to electrical energy</u> which activates the controller. The controller sends a radio signal and the car starts moving. This means that the <u>electrical energy </u> is received by the car and car starts moving. <u>The electrical energy converts into mechanical energy </u>(kinetic energy).
The more slanted the sun's rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse. In the winter, Earth tilts away from the Sun.
T&hey are heavier I believe and need a bigger engine to make it
hope i helped
Have a great day
Answer:
T = 8.19 s
, = 23 m / s
Explanation:
In the simple harmonic motion the equation that describes them is
y = A cos wt
Acceleration can be found by derivatives
a = d²y / dt²
v = dy / dt = - Aw sin wt
a= d²y / dt² = - A w² cos wt
For maximum acceleration cosWT = + -1
= -A w2
w = RA (/ A)
w = RA (1.8 9.8 / 30.0)
w = 0.767 rad / s
The angular velocity is related to the frequency
w = 2π f
f = 1 / T
w = 2π / T
T = 2π / w
T = 2π / 0.767
T = 8.19 s
For maximum speed the sin wt = + -1
= A w
= 30.0 0.767
= 23 m / s
While sliding down a hill in a sled, the force of gravity causes the sled to accelerate down the hill. The force of friction eventually causes the sled to stop. the friction force partly cancels some of the gravity force pulling the sled down. These two forces affect many motions on Earth.
