Answer: Option (B) is the correct answer.
Explanation:
As we know that the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.
But during this process of change in state of substance the temperature will cease to change for some time because unless and until all the liquid molecules do not convert into vapor state the temperature will not rise or change.
As the boiling point of water is
so the temperature ceases to change from
to
.
Therefore, we can conclude that when heating water, during
to
temperature range the temperature will cease to change for some time.
Answer:
1 ohm is equal to one volt (V)/ one ampere (1A) 1 Ohm is defined as the resistance of a conductor with a potential difference of 1 volt applied to the ends through which 1-ampere current flows. Ohms is the SI unit of electrical resistance.

Answer:The actual answer is heat.
Explanation:There is always water under a forming hurricane, the strength of the hurricane depends on the heat of the water since heat is a raw form of energy. It can transfer to the storm.
Answer:
a) 3.78 m/s
b) 3.78 m/s
Explanation:
a )From the equations of kinematics we know that
Vf - Vi = at
since Initial speed Vi = 0
acceleration = 4.2 m/s2
so we have
Vf = a t
= (4.2) (0.9)
= 3.78 m/s
velocity at t = 0.9 s. m/s is 3.78 m/s
b) If the sprinter maintains constant velocity then acceleration becomes zero.
So velocity is 3.78 m/s
