Answer:
Explanation:
Given
radius of neutron star
Centripetal force on material having mass m is given by
Gravitational Force between neutron star and mass m is
,where M=mass of Neutron star
equating centripetal Force and Gravitational Pull
Answer:
a common temperature is reached.
Explanation:
The principle of heat transfer is that heat flows from a substance of higher temperature to that of lower temperature until when a common temperature is reached.
For ice on getting in contact with a hot body; it changes to water at 0°c utilising the latent heat of fusion. After ice has been converted to water at 0°c, water starts increasing in temperature till a common temperature is reached.
Answer:
Explanation:
Two forces are 10 N and 30 N. Let us assume that two forces are acting in opposite directions. Net force will be :
F = 30 N - 10 N = 20 N
Now,
F = ma
⇒ a = F/m
So,
So, the acceleration of the object is .
Answer:
Force is repulsive hence direction of force is away from wire
Explanation:
The first thing will be to draw a figure showing the condition,
Lets takeI attractive force as +ve and repulsive force as - ve and thereafter calculating net force on outer left wire due to other wires, net force comes out to be - ve which tells us that force is repulsive, hence direction of force is away from wire as shown in figure in the attachment.
