Answer:
1.33 m
Explanation:
Tom weighs 600 N and is 2 meters from the pivot. So his moment is:
τ = Fr
τ = (600 N) (2 m)
τ = 1200 Nm
To balance the see-saw, Jeremy must create an equal and opposite moment.
τ = Fr
1200 Nm = (900 N) r
r = 1.33 m
So Jeremy must sit 1.33 m from the pivot on the other side.
Answer:
Potential Energy is the energy that is waiting to be released like at the top of the roller coaster, Kinetic energy is the energy that is moving the rollercoaster downhill fast.
Three Laws:
The rollercoaster will rest at the top, and then the gears will make it move downhill, and make it stop.
The gears make the rollercoaster move, and in reaction, it pushes back on the gears.
Absolute zero is from the Kelvin scale.
V = 60km/h
S=500km
t = ?
v = S/t
t = S/v
t = 500km / 60 km/h
t ≈ 8,33 h
Despite the risks, Human populations can be found near volcanoes. This can be associated with the availability of which natural resource?
