Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
Answer:
Q = 7272 Kilojoules.
Explanation:
<u>Given the following data;</u>
Mass = 2.0*101kg = 202kg
Initial temperature, T1 = 10°C
Final temperature, T2 = 90°C
We know that the specific heat capacity of iron = 450J/kg°C
*To find the quantity of heat*
Heat capacity is given by the formula;
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- dt represents the change in temperature.
dt = T2 - T1
dt = 90 - 10
dt = 80°C
Substituting the values into the equation, we have;
Q = 7272KJ or 7272000 Joules.
Answer:
The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Explanation:
The NUCLEUS is the center of the atom. it contains protons and NEUTRONS
protons have a POSITIVE charge
neutrons have a NEUTRAL charge
electrons have a NEGATIVE charge
