Answer:
Explanation:
A physical quantity which can be completely described by the magnitude and direction both are called vector quantities. For example, displacement, velocity, etc.
A physical quantity which can be completely explained by the magnitude only is called scalar quantity. For example, mass, time, etc.
normal force=mass*gravitational force
normal force=40*0
normal force=40
Answer:
The apparent weight of the object is 0.465 N.
Explanation:
Given that,
Weight = 0.71 N
Water level = 50 mL
object inserted = 75 mL
We need to calculate the volume of solid
Using formula of volume

We need to calculate the buoyancy force
Using formula of buoyancy force

Put the value into the formula


We need to calculate the apparent weight of the object
Using formula of apparent weight

Put the value into the formula


Hence, The apparent weight of the object is 0.465 N.
