Chemical Energy
A Brief Overview Of Chemical Energy
Chemical energy is simply energy that is stored in compounds or elements, specifically in the atomic bonds that connect atoms and molecules. In food, it's a form of potential energy because it's stored away.
Explanation:
Explanation:
It is said that the bus moves with the speed of 72 km/hr.
It means that the bus covers 72 km in 1 hour.
so,
It covers 72 * 1000 m = 72000 m in one hour.
Hope it helps :)
Answer:
0.8 m
Explanation:
Draw a free body diagram. There are three forces:
Weight force mg pulling down,
Normal force N pushing up,
and friction force Nμ pushing towards the center.
Sum of forces in the y direction:
∑F = ma
N − mg = 0
N = mg
Sum of forces in the centripetal direction:
∑F = ma
Nμ = m v²/r
Substitute and simplify:
mgμ = m v²/r
gμ = v²/r
Write v in terms of ω and solve for r:
gμ = ω²r
r = gμ/ω²
Plug in values:
r = (10 m/s²) (0.5) / (2.5 rad/s)²
r = 0.8 m
