Answer:
The ice melts mass is:

Explanation:
Kinetic Energy



Heat gained by ice= mass(g) x 80 cal
( 1 cal = 4.184 *10^7er or g cm^2/ sec^2)
Assuming no loss in heat, in the motion so both continue with temperature 0~C
To find so the mass (gm) of ice melted

Energy is defined as the ability to do work. There are two main forms of energy which are:
- Potential energy
- Kinetic energy
Chemical energy energy is a form of potential energy produced through chemical reactions. A car battery is an electrochemical that converts chemical energy into electrical energy for use in the iPod. The battery is made up of electrodes through which electron flows in one direction and current is generated by the potential difference set up
Gravitational energy is a form of potential energy that tends to pull all bodies to the center of the earth. It is an attractive force.
Electrical energy is a form of energy produced through the flow of electric current in a body. As the positive charge moves away from the strong negative plate, an electric current is produced.
Elastic energy is a potential energy stored in elastic bodies that can be stretched and are not plastic.

Answer:
d = 0.05 [m] = 50 [mm]
Explanation:
We must remember the principle of conservation of energy which tells us that energy is transformed from one way to another. For this case, the initial kinetic energy is transformed into useful work that is equal to the product of force by distance.
![E_{k}=F*d\\400 = 8000*d\\d = 0.05 [m] = 50 [mm]](https://tex.z-dn.net/?f=E_%7Bk%7D%3DF%2Ad%5C%5C400%20%3D%208000%2Ad%5C%5Cd%20%3D%200.05%20%5Bm%5D%20%3D%2050%20%5Bmm%5D)
<span>The unknown substance is silver.
I don't see a list of available substances, but let's see if there's something reasonable available that will match. First, let's calculate the density of the unknown substance. Density is mass per volume, so
273 g / 26 mL = 10.5 g/mL
Looking up a list of elements sorted by density, I see the following:
10.07 Actinium
10.22 Molybdenum
10.5 Silver
11.35 Lead
And silver at 10.5 g/ml is a very nice match for the unknown substances' density of 10.5 g/ml.</span>
