Answer:

Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:

Substitue the values into the formula.

Multiply the first numbers together. The grams will cancel.

Multiply again, this time the degrees Celsius cancels.

<u>121.905 Joules</u> are required.
The ratio between the force of sliding friction and the normal force of an object is called the coefficient of friction.

Answer:
Explanation:
There are three known subatomic particles: Electrons, Protons and Neutrons
Electrons
- It has a charge of -1
- It has negligible mass
- it is found outside the nucleus
Protons
- It has a charge of +1
- It has a mass of 1
- It is found in nucleus
Neutrons
- It has no electrical charge
- It has a mass of 1
- It is found in the nucleus
