Answer:
Tension, T = 0.1429 N
Explanation:
Given that,
Mass of the rock, m = 0.0450 kg
Radius of the circle, r = 0.580 m
Angular speed,
The tension in the string is balanced by the centripetal force acting on it. It is given by :
Since,
T = 0.1429 N
So, the tension in the string is 0.1429 N. Hence, this is the required solution.
Answer:
Explanation:
Given
mass of ice
Final temperature of liquid
Specific heat of water
Latent heat of fusion
Latent heat of vaporization
Suppose M is the mass of steam at
Heat required to melt ice and convert it to water at
Heat released by steam
and must be equal as the heat gained by ice is equal to Heat released by steam
The number of cycles of a periodic wave per unit time is called the wave's "frequency". The height at which the peaks of the waves reside is the "amplitude".
Answer:
Kinetic energy is 242.7 Joule
Explanation:
m = 47.4 kg
v = 3.2m/s²
Now,
K.E. = 1/2 × m × v²
or, K.E. = 1/2 × 47.4 × 3.2²
or, K.E. = 242.7 Joule
