Answer: Final Temperature= 40.57 deg C; Latent Heat of Fusion of Ice= 80.14 cal/g
Explanation:
The system is said to be isolated to the surroundings. All energy must remain inside the system. We can state that no loss of energy takes place, thus,
Electric field lines of positive charges are always radially outwards
So here all field lines must have tendency to move out radially as well as two field lines never intersects with each other
So here field lines also do not intersects with each other
So overall the figure C is perfectly representing the field lines of two positive charges as these lines are not intersecting and also originating from two positive charges.
So answer must be
<u><em>FIGURE C</em></u>
Newton's 2nd law of motion:
Force = (mass) x (acceleration)
Divide each side
by 'acceleration': Mass = (force) / (acceleration)
= (2,500 N) / (200 m/s²)
= 12.5 kg
Under free fall, the object is falling with a velocity that is increasing uniformly. Since the gradient of position-time graph reflects the velocity, the gradient is increasing, i.e. curve.
