To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T],
Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6
Therefore, V = 352.6 m/s.
Answer:
b
Explanation:
because the weight/work increases bcz of the time period
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that the speed of light is given as
now the frequency of the light is given as
so we have
Part b)
Position of Nth maximum intensity on the screen is given as
so here we know for 3rd order maximum intensity
n = 3
L = 1.4 m
Part c)
angle of third order maximum is given as
Answer:
13 m/s^2
Explanation:
The acceleration of gravity near the surface of a planet is:
g = MG / R^2
For planet 1, g = 26 m/s^2.
The gravity on planet 2 in terms of the mass and radius of planet 1 is:
g = (2M)G / (2R^2)
g = 1/2 MG / R^2
Since MG/R^2 = 26 m/s^2, then:
g = 13 m/s^2
Answer:
Mass of receiver is 92 kg
Explanation:
We have given mass of tackler
Let the mass of receiver is
When tackler moving alone velocity is m/sec
And when tackler and receiver is together velocity is = 2.5 m/sec
So from conservation of momentum
So mass of receiver is 92 kg
