The particles vibrate against each other in a soild state........i think
Answer: chemical → kinetic → electrical → light
Explanation: At the same time when the generator lights up the bicycle lamp the lamp lights up using electrical energy so mechanical energy is also transformed into electrical energy.
In the 1970, the average American ate only 2 pounds of sugar a year. In 1970, we ate 123 pounds of sugar per year. Today, the average American consumes almost 152 pounds of sugar in one year. This is equal to 3 pounds (or 6 cups) of sugar consumed in one week!
The frequency of a wave is a measure of the number of waves that passes through a point per unit of time. It has SI units of s^-1. It is also equivalent to Hertz (Hz). We calculate the frequency of the wave described as follows:
Frequency = 5 waves / 2 s = 2.5 / s or 2.5 Hz
Answer:
Q=0.16*c kJ
Explanation:
Heat transfer and energy changes is related by the equation
Q=mcΔT
where
Q=heat transfer
m=mass of substance
c=specific heat of the material
ΔT= change in temperature
Given
m= 4 kg
c=c
ΔT=40° C
Q=4*c*40
Q=160c
Q=160/1000*c kJ
Q=0.16*c kJ
