Answer:
The magnetic field is doubled.
Explanation:
What happens to the strength of the magnetic field if one more 1.5 v dry cell is added?
The magnetic field due to a current carrying conductor is directly proportional to the current flowing in the wire.
If we connect one more battery of 1.5 V so the voltage is doubled and according to the Ohm's law, as the resistance of wire is constant, so the current in the wire is also doubled.
When the current doubles, the magnetic field produced by the wire is also doubled.
To solve the problem it is necessary to refer to the definition of entropy.
Entropy is defined aso
Where,
Heat exchange
T = Temperature
Since the heat exchange is conserved and it is an isothermal process where the temperature remains constant the change in entropy remains the same, ie 
(Reamins same)
Therefore the correct answer is C.
Infrared rays are used in many forms of thermal technology. This is also used in weather reports to find the temperature of the surrounding areas.
Answer:
B) Remains constant
Explanation:
The motion of the ball is the motion of a projectile, which consists of two separate motions:
- A horizontal motion with constant velocity, since there are no forces acting along the horizontal direction (if we neglect air resistance)
- A vertical motion with constant acceleration, due to the presence of the force of gravity (pointing downward), that accelerates the ball towards the ground with acceleration g=9.8 m/s^2.
We are only interested in the horizontal motion of the ball: we said that there are no forces acting along the horizontal direction, therefore the horizontal component of the the velocity of the ball is constant.
