Which factors can affect the amount of friction acting on an object on a solid surface
2 answers:
Well gravity is always a factor on the friction of objects.
If we're talking about friction itself, then mass almost certainly plays a role.

The answer is yes
They are isotopes.
If 56.5kJ are needed to raise the temp by 90°C and if the heater is 60% efficient that means that:
60% X y = 56.5kJ
where y is the electrical energy in kJ that the heater will use.
y = 94.2kJ
4.9 eV is the correct answer
