Answer:
and
Explanation:
The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N
to the horizontal
Required
Solve for the x and y components
Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.
---- y component
---- x component
Calculating the y component.
Substitute 15 for Force and 36.7 for
becomes
Make y the subject
Calculating the x component.
Substitute 15 for Force and 36.7 for
becomes
Make y the subject
<em>Hence, the x and y components of the force are: 8.964N and 12.027N respectively.</em>

Answer:
Zero
Explanation:
Acceleration is defined as the rate of change in speed. The speed during the first second is 9m/1s = 9m/s. During the second second is again 9m/1s = 9m/s and again 9m/s for the third second. Being the speed the same, the acceleration is 0
Answer:c
Explanation:
The buoyancy force on toy depends upon the volume of toy under pool water.
According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.
Buoyancy force is given by
where =density of fluid
V=volume of object under water
g=acceleration due to gravity
