I think it would be at 3 or 6 but I would go with 3 not really sure tho
In an attempt to reduce our dependence on non-renewable resources, and cut down on the harm to the environment, we could burn biomass to produce electricity.
Answer:
a. The disk
b. Because it has the smallest rotational inertia
Explanation:
a. Which object do you expect to reach the bottom of the inclined plan first?
I would expect the disk to reach the bottom first.
b. Why?
This is because the disk has the smallest rotational inertia.
The rotational inertial of the hollow sphere, disk and ring are 2/3MR², 1/2MR² and MR² respectively.
Since the three objects are rolling from the same height, they have the same mechanical energy.
But, since the disk has the smallest rotational inertia, it would have the smallest rotational kinetic energy and largest translational kinetic energy. The disk's smaller rotational kinetic energy will cause to rotate less but translate more than the other objects and thus reach the bottom first.
Answer:
When a moving bus stops suddenly, the passenger are pushed forward because of the inertia of the passengers. ... Because the lower part of the body comes to rest with the bus while the upper part tends to continue its motion due to inertia.
Explanation :
The passengers in a bus tend to fall backward when it starts suddenly due to inertia as the passengers tend to remain in the state of rest while the bus starts to move. When the bus stops suddenly, people fall forward because their inertia as they are in state of motion even when the bus has come to rest.

Answer:
19620 Watt = 19.62 kWatt
Explanation:
Power output (P) is work (W) divided by time (t): P = W/t
A work (W) is a product of a force (F) and a distance (d): W = F · d
Since the force is a product of mass and acceleration: F = m · a
then work would be: W = m · a · h
P = W/t
W = m · a · h
P = m · a · h / t
We have:
P = ?
m = 1000 kg
a = 9.81 m/s² (gravitational acceleration on the Earth)
h = 10 m
t = 5s
P = m · a · h / t = 1000 kg · 9.81 m/s² · 10 m / 5 s = 19620 Watt = 19.62 kWatt
