Answer:
The distance is 54.6 m
Explanation:
Given that,
Mass = 2.0 kg
Frictional coefficient = 0.21
Initial velocity = 15 m/s
We need to calculate the acceleration
Using formula of frictional force
We need to calculate the acceleration
We need to calculate the initial velocity
Using equation of motion
Put the value
Hence, The distance will be 54.6 m.
<h2>Answer:</h2>
The sun emits radiation in wavelengths of 10nm to 1mm.
<h3>Explanation:</h3>
The sun emits radiations of different types in electromagnetic spectrum.
99% of radiations are :
- Visible light: 400nm to 700nm
- Ultraviolet rays: 10nm to 400nm
- Infrared rays: 700nm to 1mm
Answer:
U = 5.37*10^33 J
Explanation:
The gravitational potential energy between two bodies is given by:
G: Cavendish's constant = 6.67*10^-11 m^3/kg.s
For three bodies the total gravitational potential energy is:
BY replacing the values of the parameters for 1->earth, 2->moon and 3->sun you obtain:
hence, the total gravitational energy is 5.37*10^33 J
