Answer: a= 0.175 m/s²
Explanation: To solve for acceleration we will use Newton's Second Law of Motion which is F=ma. Since there are multiple forces acting on the object, we need to summate the forces involved. Derive to find acceleration.
a= F/m
= 5 N - 3.6 N / 8 kg
= 0.175 m/s²
Answer
Correct Answer is a.(spikes)
Explanation:
option a is correct because here serves, rotation and spikes all the three words are using as object.
The volleyball team practiced their serves, rotations, and spikes.
option b cannot be correct because here spiking is used as a verb and sentence(The volleyball team practiced their serves, ) is in past indefinite form and we cant use word spiking here because this form of verb is used in continues form of sentences only.
Option c cannot be correct as because in this option ""spikes the ball" spikes is used as a verb which can be used in present indefinite form of sentence only but here sentence is in past indefinite form.
Again option d cannot be correct because in this option ""spikes over the net" spikes is used as a verb which can be used in present indefinite form of sentence only but here sentence is in past indefinite form.
Answer:
False
Explanation:
Warmer air is less dense than cold, which is why warm air tends to rise and cold air sinks. Being acted on by gravity, colder, denser air weighs more and exerts greater pressure per unit area.
Answer:
is the height of the TV screen.
Explanation:
Given:
diagonal of TV screen, 
width of TV scree, 
As we know that the TV screen is rectangular in shape so including its height and with along with the diagonal forms a right angled triangle in which the diagonal is the hypotenuse of the triangle formed so.
is the height of the TV screen.
Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.
