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
Explanation:
Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.
The frequency and the wavelength has an inverse relationship.
For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.
The frequency range of visible region is from 400 nm to 700 nm.
Answer:
The law of conservation of energy is the preserved form of energy.
Option (1) is correct that is the total amount of energy in the universe remains constant.Because energy is conserved.
Option (3) is correct since, it is conserved so, it can not be created or destroyed.
Option (4) Energy can change from one type to another like mechanical to electrical energy but it will remain conserved.
Option (5) is correct because in closed, isolated system energy is conserved.
The answer is 523.60 rounded. To get this use the formula: V=4/3 • π • r^3 = 4/3·π·(53) ≈ 523.59878. Which is four over three, multiplied by “pie” multiplied by the radius cubed. (Which is 5 • 5 • 5). To get the radius, you split the diameter in half. For you equation, “1/2 of ten is five” so the radius is five. Hope this helps!
