<span>the force on the ball is at right angles to the ball's motion</span>
Answer:
if the image is on the book yes , no its can be both
Explanation:
To measure the fluids that you will be using such as water or other chemicals if your mixing them and they have to be precise measurements
Answer:
0.05 m/s (It normally stays the same if no outside forces interferes)
Explanation:
It is 0.05 because of you pay attention to the info, it will say that the momentum ”before” the 2 marbles collision is 0.05 m/s, so it is still 0.05 m/s.
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity
Electric field E = 700 N/C
Electric force will be equal to , here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
So charge will be equal to
