Answer:
False
Explanation:
<em>If one of the bulbs is removed from the series, the other bulb will not come on at all.</em>
This is because the removal of one of the bulbs would interrupt the flow of current though the entire circuit.
Hence, that the other one will get brighter if one of two bulbs in a circuit is removed from its socket is not true.
Answer:
Explanation:
Let the forward displacement is taken is positive, and the backward displacement is taken is negative.
first displacement = + 18 cm
second displacement = - 6 cm
third displacement = - 12 cm
net displacement = 18 - 12 - 6 = 0 cm
Answer:

3257806.62409 m/s
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of Sun = 
r = Radius of Star = 20 km
u = Initial velocity = 0
v = Final velocity
s = Displacement = 16 m
a = Acceleration
Gravitational acceleration is given by

The gravitational acceleration at the surface of such a star is 

The velocity of the object would be 3257806.62409 m/s
