Answer:
1.6 x 10⁻⁶ J/m³
Explanation:
I = Intensity of electromagnetic radiation = 475 Wm⁻²
U = average total energy density of electromagnetic radiation
c = speed of electromagnetic radiation = 3 x 10⁸ m/s
Intensity of electromagnetic radiation is given as
Inserting the values
U = 1.6 x 10⁻⁶ J/m³
1 particles have got forces of attraction between them
2 they vibrate and rotate at a fixed point
3 they gan heat energy in order for them to melt
4 particles are closely packed together
Answer:
There is no gravity in outer space so how will any object fall in the first place
Also the principle of terminal velocity is limited to free fall where the acceleration is equal to the gravity of the planet
<span>If the </span>base<span> has 6 sides, the </span>prism<span> will also have 6 </span>lateral faces. It will all depend how many sides the base has and the lateral face of the prism will equal to the number of sides of the base. In short, if the base<span> has 'x' sides, then the </span>prism<span> will </span>have<span> 'x' </span>lateral faces<span>.</span>
Answer:
Elastic collision
Explanation:
The interaction of two particles is called collision. There are two types of collision i.e. elastic collision and inelastic collision.
Two bouncy balls colliding with each other is an example of elastic collision. In this type of collision the momentum and kinetic energy of the bodies remains constant i.e.
and
Where
m₁ and m₂ are masses of two balls A and B
u₁ and u₂ are initial velocities of ball A and B
v₁ and v₂ are final velocities of ball A and B
