The amount of energy needed to increase the temperature of a substance by
is given by
where
m is the mass of the substance
is its specific heat capacity
is the increase in temperature
The water volume is
, since its density is
, the mass of this sample of water is
The water specific heat capacity is
and the increase in temperature is
Therefore, the amount of energy needed is
Answer:
(a) Magnetic force 
(b) Acceleration 
(C) Speed will remain same
Explanation:
We have given velocity of alpha particle v = 520 m/sec
Magnetic field B = 0.034 T
Charge on alpha particle 
Mass of alpha particle 
Angle between velocity and magnetic field 43°
(a) Force acting on the particle is equal to
(B) According to newton's law
F = ma. here m is mass and a is acceleration.
So acceleration
(c) As the magnetic force is always perpendicular to velocity so speed will remain same neither decreases nor increases.
Answer:
The Answer is B)0.2 kg • m/s
