Answer:
The further the distance from the pivot the greater the force
Explanation:
Practical example below
Distance of door handle is 5m. Force is 5N
Moment = Force × distance
=5×5
=25Nm
Distance of door handle is 7m. Force is 5N
= 7×5
=35Nm
Therefore proven correct
Answer:
The answer is 'an equinox'.
Answer:
Increase in temperature of water = 0.53 °C
Explanation:
Change in mechanical energy = Potential energy
Potential energy = mgh
Mass, m = Mass of 1 L water = 1 kg
Acceleration due to gravity, g = 9.81 m/s²
Height, h = 225 m
Potential energy = 1 x 9.81 x 225 = 2207.25 J
Because of this 2207.25 J water gets heated.
Heat energy, E = mcΔT
Mass, m = Mass of 1 L water = 1 kg
Specific heat of water, c = 4200 J/kg/C
Energy, E = 2207.25 J
Change in temperature, ΔT = ?
Substituting
2207.25 = 1 x 4200 x ΔT
ΔT = 0.53 °C
Increase in temperature of water = 0.53 °C
The answer is A 1/4f because it is doubled to 2q and you need to flip it
