Answer:
What is Kinetic and Potential Energy? In Physics, energy is used to refer to an ability to do work. Energy exists in various forms. This includes Gravitational energy, Chemical energy, Radiant energy, Mechanical energy, Sonic energy, Thermal energy, Nuclear or atomic energy, Magnetic energy and Electrical energy amongst many others.
Explanation:
<h2>
Oxygen is moving at 483.63 m/s</h2>
Explanation:
Kinetic energy = 0.5 x Mass x Velocity²
Kinetic energy = 6.21 x 10⁻²¹ J
Mass = 5.31 x 10⁻²⁶ kg
Substituting
Kinetic energy = 0.5 x Mass x Velocity²
6.21 x 10⁻²¹ = 0.5 x 5.31 x 10⁻²⁶ x Velocity²
Velocity² = 2.34 x 10⁵
Velocity = 483.63 m/s
Oxygen is moving at 483.63 m/s
Answer:
Rise in temperature will be
So option (c) will be the correct answer
Explanation:
We have given solar radiation on the panels
25 % of the conversion efficiency = 25 % 1000 = 250
Area is given
So radiated power
Time is given t = 1 hour = 3600 sec
So energy
Mass of water m = 30 kg
And
So rise in temperature
So option (c) will be the correct option
Answer:
The answer is:-
