Answer:
Yes, It is true.
The acceleration due to gravity is caused by field force.
Answer:
Explanation:
Given
Object is thrown with a velocity of 
Acceleration due to gravity is -g (i.e. acting downward)
Vertical distance traveled by object is given by
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
at maximum height final velocity is zero


time taken to reach maximum height
using
v=u+at
0=9-gt

Answer:
220 ohms
Explanation:
I = V / R
0.25 = 110 / R
R = 110 / 0.25
R = 440 ohms
Equivalent resistance = 440 ohms
Resistance of single light bulb = Equivalent resistance / number of bulbs
= 440 / 2
= 220 ohms
