Answer:
Converted to heat energy
Explanation:
Some of the elastic potential energy is transformed into heat energy. When we stretch a rubber band, it is often observed that the rubber becomes warmer after the stretch and even during the stretch.
Some energy in the band initially at rest will be converted into elastic potential energy and heat energy as it is stretched .
- The heat energy is not usually accounted for since the major concern most times is the elastic energy.
- In this process, heat energy becomes a waste energy.
- By deducing the efficiency, we would find that this transformation is not efficient as predicted by one of the laws of thermodynamics.
Answer:
Value of 
Explanation:
We have given
In first case resistance is 
and current is 1.8 A
Let the potential difference is v
So 
----eqn 1
In second case resistance is 
and current is 1.6 A and potential difference will be as it is a series connection
So 
----eqn 2
From eqn 1 and eqn 2
That is not yet possible. that technology has not yet been invented.
==> Infrared waves from the sun, green light from the sun, and X-rays from the sun, all travel through vacuum.
==> Ocean surf waves travel through water.
==> Microwaves in an oven travel first through air, and then later through meatloaf or chicken.
==> Seismic waves (earthquakes) travel through rocks and dirt.
Answer:
0.52°
Explanation:
refractive index for blue light, nb = 1.640
Refractive index for red light, nr = 1.595
Angle of incidence, i = 30°
Let the angle of refraction for blue light is rb and the angle of refraction for red light is rR.
By use of Snell's law for blue light
By use of Snell's law for red light
The angle between the two beams, 
θ = 18.27° - 17.75°
θ = 0.52°
