When a match stick is struck, some of the chemical energy is transformed into heat and light and the rest is converted into matter.   A match stick has a lot of chemical energy stored in it. When its struck, It start burning. The chemical energy stored in it is transformed into heat energy and light energy. The rest of it turn into ashes and reaction gases.

A 4.00-kg cylinder, of length 21.0 cm and diameter 12.0 cm , about the central axis of the cylinder, if the cylinder is thin-wal
insens350 [35]
We are given
m = 4 kg
L = 21 cm
D = 12 cm
Thin-walled cylinder

I think what is asked is the moment of inertia of the cylinder about its axis. The formula is
I = MR²
substituting the given values
I = 4 (12/2)²
I = 144 kg cm²

Acceleration due to gravity = 9.8m/s

Height = 10 m

Work done = mgh

= 100 x 9.8 x 10

= 9800 J

Hope this helps!

Morgarella [4.7K]
Given:
I=8A
t=2second
Potential difference,V=120-100=20volt
Workdone=V×i×t
=20×8×2
=320 joule.

As 390 g of hot milk cools in a mug, it transfers 30,000 J of heat to the environment. What is the temperature change of the mil
kotykmax [81]
The correct answer is 19.72 °C. The first step is to determine the amount of heat that was lost per gram (30,000 J) / (390 g) = 76.92 J/g. Then to determine the temperature change, divide 76.92 J/g with the given specific heat of milk (76.92 J/g) / (3.9 J/g°C) = 19.72 °C.
