Answer:27 km per hour West + 17 km per hour North
Answer: TENSION and WEIGHT
Explanation:
Force experienced by the spring is called TENSION while the WEIGHT is the gravitational pull on the body towards the earth surface. Therefore the forces acting on the cart are TENSION and WEIGHT(weight acts downwards (along negative y-axis) while the TENSION upward(along positive y-axis).
The suns gravitational pull
Answer:
Frictional force is produced when two bodies are rubbed against each other. It is the force that oppose the motion and therefore it stops or slow down a moving body.It depends upon the roughness or smoothness of the surface of the body in contact.Rough surface have more friction that the smooth surface. Similarly, the heavier body produces more friction than a lighter body. Frictional force acts in the opposite direction of the motion of the body.
Answer:
true.
Explanation:
z-score gives an idea of how far the value of data is from the mean point. Basically is the measure of a standard deviation below or above the mean.
More the deviation of the data from the mean more is the standard deviation.
Z-score or value is calculated by the expression given below:

x is the value
μ is the mean
σ is the standard deviation
Hence, the statement given is true.
