Answer:
Catapult on the ground: Normal, gravity
Catapult (I'm assuming launching marshmallow): Reaction of Force Applied
Marshmallow: Force Applied
Explanation:
This is the forces that act on a stationary object and a launched object. The catapult may also experience a force friction if your teacher is taking a more practical sense.
Answer:
7.24 Ω
Explanation:
Power = energy / time = 195 J / 9.81 = 19.88 W
and power = V² / R
R resistance = 12 V² / 19.88 W = 7.24 Ω
The earth tilt about 23 degrees which leads to the formation of seasons on earth.
<h3>At what degree the earth tilt?</h3>
This is tilted at 23 degrees from the vertical. The northern hemisphere is in the winter season.
This is the path as the earth revolves around the sun. It takes 1 year to complete this path.
This is the path as the earth rotates around its.
So we can conclude that the earth tilt about 23 degrees which leads to the formation of seasons on earth.

Answer:
344.8 Hz
Explanation:
The frequency of a wave is given by:
where
v is the speed of the wave
is its wavelength
Here we have
v = 793 m/s
Substituting into the equation, we find
