Answer:
Explanation:
In this case mechanical energy is conserved, which means that the sum of the initial kinetic energy and initial potential gravitational energy will be equal to the sum of the final kinetic energy and final potential gravitational energy:
Which in our case will be:
Which, since 
, 
, 
, 
and canceling <em>m</em> means that:
Solving for the final velocity we get:
Answer:
When equal and opposite forces meet each other, it results in motion and they would repel away from each other, causing the asteroid to be sent away from the earth.
Explanation:
Newton's Third Law states that every action has an equal and opposite reaction.
Solution :
The electric field between two plates is given by
where
permitivity of free space
q = charge
A = surface area
It is given that :
the radius of the circular plates , r = 30 mm
the current, I = 0.43 mA
Therefore, Magnetic field can be found by
Answer:
The material through which sound is travelling
Explanation:
Solid has compact molecules so sound waves can moove easily and fastly.
In case of liquid, it has relatively less inter- molecular space so, sound transfers slowly..
Hope you can generate meaning regarding spped of sound in gas...
MAKE ME BRAINLIST PLEASE...
