The sun Doesnt rotates as we know all . But it rotates with the wjole our Milky Way Galaxy. This movement is so slow that we cant even recognise that we are shifted.
This we know because we all had studied about the solar system and space.
By this study we can say that Sun Rotates.

Answer: B
Explanation:
Because the ramp is too high, the forces aren't enough to push onto the car stuck down.
The turn and voltage ratio of a transformer can be simply expressed by the equation:
Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.
Plugging in the given values, we have:
25 turns / 100 turns = Vs / 40 volts
Vs = 40 volts (25 turns/100 turns)
Vs = 10 volts
The answer is D.
Answer:
A) If the paintball stops completely the magnitude of the change in the paintball’s momentum is
B) If the paintball bounces off its target and afterward moves in the opposite direction with the same speed, the change in the paintball’s momentum is
C) A paintball bouncing off your skin in the opposite direction with the same speed hurts more than a paintball exploding upon your skin because of the strength exerted is twice than if it explodes.
Explanation:
Hi
A) We use the formula of momentum , so we have
B) We use the same formula above, then due we have a change of direction at the same speed, therefore the change in the momentum is the double so
.
C) The average strength of the force an object exerts during impact is determined by the amount the object’s momentum changes. therefore
, as we don't have any data about the impact time but we know momentum is twice, time does no matter and strength is twice too.
The volume of the sample is 48.39 cm³.
<h3 /><h3>What is volume?</h3>
The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface
To calculate the volume of the sample, we use the formula below
Formula:
- D = m/v
- v = m/D................ Equation 1
Where:
- m = Mass of the smaple
- D = Density of the sample
- v = Volume of the sample.
From the question,
Given:
Substitute these values into equation 1
Hence, the volume of the sample is 48.39 cm³.
