Motion by definition is the movement of things above or below the surface of gravity
Given: Mass m = 0.50 Kg; Force = Weight = mg F = (0.50 Kg)(9.8 m/s²)
F = 4.9 N
Displacement x = 3.0 cm convert to meter x = 0.03 m
Required: Spring constant k = "
Formula: F = kx
k = F/x
k = 4.9 N/0.03 m
k = 163.33 N/m
Answer: 100 N
Explanation: Taking into account the second Newton Law the total force applied to any system is equal to the mass *acceleration.In this case the crate moves at constant speed so the accelaration is zero. In order to satisfy this fact, the friction force must be equal the applied force of 100 N .
Answer:
solids cannot flow because the molecules a held tightly together
Hello.
The answer is
<span>Scientific knowledge can answer all of society's questions.
</span>
All Science has limits, some things sciencets cant do things becuase its not possible or its just not for science.
It cant be the first one becasue everyone chnages there mind.
It cant be two becasue sciencet only do experments that are safe so they wil be durable.
So its C
Have a nice day
