While ice melts, it remains at 0 °C, and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules per gram, and the heat of vaporization at 100 °C is about 2,230 joules per gram. So it will be C
A magnetic field is experienced by the charged particle in the +y direction.
Discussion:
- The right thumb rule states that the magnetic field lines will be perpendicular in the area to the conductive wire's left in which the electric potential is traveling.
- The direction of the current may be determined by looking at the positive charge's (X direction) motion. According to Fleming's left-hand rule, the force on a positive charge will be in the +y direction because the positive charge is moving in a leftward direction, which will also be the direction of the current.
Fleming's left-hand rule:
In accordance with Fleming's Left Hand Rule, the thumb, forefinger, and middle finger of the left hand should be positioned perpendicular to one another. The thumb should point in the path of the power exerted by the conductors, the forefinger should point in the magnetic field direction, and the middle finger should point in the path of the electric current.

Answer: No crash landing on the surface of the moon and there is no vibration due to low acceleration due to gravity.
Explanation:
The rocket ship can't land on the surface of the moon because it depends on winged flight for its controlled descent to the surface of the Earth. Since the moon has no real atmosphere, the wings would not be able to glide the craft smoothly to the moon's surface.
The acceleration due to gravity in the moon is very low compared to the earth. The astronauts cannot experience vibration ripple through the Moon’s surface beneath their feet because the low level acceleration due to gravity will drastically affect the weight of the ship.
Answer:
Option-A
Explanation:
In the given question, two cyclists of equal weight are riding the same mountain with cycles of the same weight but Joe reaches the top before Bob.
This scenario can be explained in terms of power and if we ignore the force of wind resistance and friction. Power refers to the work done per unit time, therefore, P= W/t. Since Joe rides up straight earlier than Bob shows that Joe has exerted more power than Bob that is the amount of work done by the Joe is greater than Bob.
Thus, Option-A is the correct answer.
