Mass and distance
force /pull of gravity decreases with the increase in separation between the two bodies
the amount of gravity an object possesses is proportional to the mass of that object.
A research question that would complete the third question you need that are related to the first 2 questions which are:
- “what type of masks help prevent fog on glasses when breathing?”
- “does a mask’s material affect the level of fog on glasses as an effect of breathing?”
Would be: "Are there any available masks that could prevent fog on glasses that could be improved upon"?
This new research question would help you find out if there is an already existing mask that could be made better.
<h3>What is a Research Question?</h3>
This refers to "a question that a research project sets out to answer". and seeks to give answers to particular phenomena.
Hence, we can see that the new research question Would be: "Are there any available masks that could prevent fog on glasses that could be improved upon"?
This new research question would help you find out if there is an already existing mask that could be made better.

#SPJ1
There are three forces acting on the book.
1. Force due to gravity
2. Force exerted downward by the hamster
3. Normal Force in reaction to the downward forces
Since the book is not moving, the net force is zero. The summation of all forces must be zero. Then we could find the normal force which is unknown (denoted as x).
∑F = -(4 kg)(9.81 m/s2) - 3 N + x =0
∑F = -39.24 N - 3N + x =0
x = 42 N
Therefore, the normal force is 42 N.
Answer:
The answer is C 1.8V and 0.38A
Answer:
C) 1 s
Explanation:
The period of a mass-spring system is given by the formula:
where
m is the mass hanging on the spring
k is the spring constant
As we can see from the equation above, the period of the system does NOT depend on the initial amplitude of the oscillation. Therefore, even if the initial amplitude is changed from 5 cm to 10 cm, the period of the system will remain the same, 1 s.
