Answer:
White dwarf
Explanation:
The Hertzsprung-Russell Diagram shows the mass of stars, the color, temperature and their brightness.Stars that lie below the main sequence area such as the White dwarf have the smallest initial mass.A white dwarf star has a mass less than that of the Sun.
Answer:
F_net = B -W
The forces of action and reaction are the weight of the balloon that is the force of attraction of the Earth and the outside so the balloon pulls the earth that has an upward direction and is applied to the planet
Explanation:
A hot air balloon is subjected to the force of its weight directed towards the center of the Earth. The thrust due to the cold air released, this thrust is directed upwards.
If we assume that the balloon rises at a constant speed
F_net = B -W
F_neta = ρ g V_body - ρ_body g V_body
The forces of action and reaction are the weight of the balloon that is the force of attraction of the Earth and the outside so the balloon pulls the earth that has an upward direction and is applied to the planet
For the answer to the question above, we have to use this formula
Pressure = P = force / area
Then, just substitute the values of the formula
force = mg = 2(10) = 20 N
area = A = 1 cm² = [1 x 10 ̄ ²]² m²
=> P = 20 N / [1 x 10 ̄ ²]² = 200 x 10³ Pa
= 200 kPa
I hope my answer helped you. Have a nice day!
- The bullet can travel about distance of (2115 m)
- Velocity can be regarded as the ratio of distance to time
- Velocity= (distance / time)
Given: velocity= 450 m/s
Time= 4.7s
- Distance= ( velocity × time)
<em>If we substitute the values</em>
= 2115 m
Therefore, the bullet can travel about 2115 m
