Answer:
A force that resists motion between two objects that are in contact; rubbing together of two objects = <em>Friction</em>
<em />
The tendency of an object to float = <em>Buoyancy</em>
<em />
A push or pull; any quantity that produces or is capable of producing motion = <em>Force</em>
<em />
A universal force that every mass exerts on every other mass; this keeps us down on earth = <em>Gravity</em>
<em />
A free body diagram is a diagram that labels all the forces acting on an object. This allows us to find the net force on an object = <em>Free body diagram</em> (it literally says it in the definition lol)

Answer:
The answer is
<h2>158.4 kgm/s</h2>
Explanation:
The momentum of an object when given it's mass and velocity can be found by using the formula
<h3>momentum = velocity × mass</h3>
From the question
velocity = 2.2 m/s
mass = 72 kg
The momentum is
momentum = 2.2 × 72
We have the final answer as
<h3>158.4 kgm/s</h3>
Hope this helps you
Answer:
Scientists believe that light is made of waves because experiments have shown that, based on Huygens's principle, waves have the ability to bend and change direction.
Explanation:
An advantage of sustainable energy is that it diversifies the energy supply and reduces importance on imported fuels.
A disadvantage is that all types of gaining access to sustainable energy requires a lot of space/ land. This may prevent important necessities such as housing to not have enough land. Hope this helps ;)
Answer:
B. Marginal cost equals long-run average total cost.
Explanation:
The zero profit condition implies that entry continues until all firms are producing at minimum long run average total cost. Since the marginal cost curve cuts the long run average total cost curve at its minimum point, marginal cost and long run average total cost must be equal in long run equilibrium.
