A ball thrown with 50N of force accelerates at 25 m/s2.  What is the mass of the ball?
MrRissso [65]
F=ma
Force is 50N. Acceleration is 25 m/s^2.
50N=m*25 m/s^2
Divide both sides by 25.

How does changing the voltage in a circuit affect the current in the circuit
Tasya [4]
The formula for the voltage is shown below:
Voltage = Current x Resistance
V=I x R

When we change voltage:
I =V/R or R=V/I
Increasing the voltage in an electrical circuit will also increase the current value, as well as the resistance of the load,

Several days after snowfall , the roofs of some homes on your street have almost no snow on them, while the roofs on other homes
Alina [70]

Explanation:

This due to thermal insulation of some of the roof.

An insulator is body is a poor conductor of heat and will require high thermal energy to cause temperature changes.

  • A house with a roof that is thermally insulated will have poor heat conduction.
  • Since little heat is conducted, there wont be enough thermal energy to melt the snow.
  • Thermal energy is directly related to heat.
  • A house that is not insulated will absorb a lot of heat.
  • This will cause the snow to melt very fast.
