Answer:
8 electrons in the third energy level
Explanation:
From the description,the third energy level has 8 electron (represented by the small green balls you describe)
Answer:
What happens to the density of an object if the object is cut in half? ... The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.

Answer:

Explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated with the following formula.

The mass of the object is 4.7 kilograms. The velocity of the object is 7 meters per second.
Substitute the values into the formula.

Solve the exponent.
- (7 m/s)²= 7 m/s * 7 m/s = 49 m²/s²

Multiply the numbers together.


Convert the units. 1 kilogram square meter per square second is equal to 1 Joule.

The object has <u>115.15 Joules</u> of kinetic energy.
Given:
ρ = 1.18 kg/m³, density of air
v = 8 m/s, flow velocity
Q = 9 m³/s, volumetric flow rate
The minimum power required (at 100% efficiency) is

The actual power will be higher because 100% efficiency is not possible.
Answer: 339.8 W (nearest tenth)
Momentum is simply a quantity that measures the impact of a moving body over something is due to the mass it posseses or the velocity with which it is moving.
Mathematically,ut is the product of mass and velocity of a body.
It is represented by capital p...(P)
P=mv
Solution to the problem:
we know P=mv
For mass,eliminate m from the equation,
m=P/v
Put values,
m=5000/5=1000kg
