Answer:
Charged objects have an imbalance of charge - either more negative electrons than positive protons or vice versa. And neutral objects have a balance of charge - equal numbers of protons and electrons. ... Their presence (or absence) will have no direct bearing upon whether an object is charged or uncharged.
Thermal energy, or heat, is the internal energy in substances; it is the vibration and movement of the atoms and molecules within a substance. The more thermal energy in a substance, the faster the atoms and molecules vibrate and move. Geothermal energy is an example of thermal energy.
Answer:
9kg
Explanation:
According to Newton's second law, Force=Mass x Acceleration.
Since we have the Force and the Acceleration, we can plug the values in and solve for mass using this equation:
90N = Mass x 10m/s
Divide both sides by 10:
90/10=Mass x 10/10
Mass = 9
The Mass of the object is 9kg.
Hope this helped!
