Answer:
Normal Force, Applied force, Gravitational Force, Spring Force
Explanation:
Normal Force so that he does not fall into trampoline, spring because the trampoline spring down when the force goes down, then up putting force upwards, gravitation because of gravity, and applied because of jumping
Answer:
42 Hz
Explanation:
Given,
Speed ( v ) = 210 m/s
Wavelength ( λ ) = 5 m
To find : Frequency ( f ) = ?
Formula : -
v = f λ
f = v / λ
= 210 / 5
f = 42 Hz
Answer:
The answer to your question is: letter D.
Explanation:
a.The mass that a mole of substance has, measured in grams per mole. Density is not measure in moles, so this is not the correct answer.
b.The amount of substance dissolved in a liquid, measured in moles per liter. The substance dissolved in a liquid must be measure in grams not in moles, so this answer is incorrect.
c.The mass of substance dissolved in a liquid, measured in grams per milliliter. I think that this definition is correct but is incomple, so this answer is wrong.
d.The ratio of a substance's mass to its volume, measured in grams per milliliter and also equivalent to grams per cubic centimeter. This is the right description to density, so this is the correct answer.
<span>The thruster releases
small amounts of substance (in the form of a gas or liquid) at very high speed
out of the nozzle. Since Newtons 3rd
law states that each action has an equal and opposite reaction, therefore
spacecraft should also experience a push in the opposite direction</span>. Therefore
the spaceship will move. This will only stop when it faces an equal opposite
force.
Answer:
<span>c. the spaceship will move and will not stop until it is
stopped by an equal and opposite forced</span>
