Answer:

Explanation:
Given:
- Length of the beam,

- speed of the beam,

- magnitude of the vertical magnetic field,

According to the Faraday's law the emf induced in a rod passing transversely through a magnetic field is given as:



The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.
Answer:
The final temperature of the two objects is the same.
Explanation:
The expression for the heat energy in terms of mass, specific heat and the change in the temperature is as follows:

Here, Q is the heat energy, m is the mass of the object, c is the specific heat and
are the final temperature and initial temperature.
According to the given question, Two objects of the same mass, but made of different materials, are initially at the same temperature. Equal amounts of heat are added to each object.
............(1)
.............(2)
From (1) and (2),



Therefore, the final temperature of the two objects is the same.

Answer:<em> Option (D) is correct.</em>
Explanation:
Considering the hypothesis elaborated in this comprehension, it's given that areas that tend to lie near forest fires usually have extra positive strikes since smoke carries positively charged particles. In rudimentary term, this states that occurrence of positively charged particles will result in extra positive strikes.
Option (D) states that occurrence of extra positive strikes will be there even weeks after the charge of smoke particles have been dissociated.
Therefore this option, most seriously undermines the hypothesis.
