Missing question: (found on google)
<em>"What is the force of the pitcher's hand on the 0.145 kg ball during this acceleration phase?
</em>
<em>Express your answer with the appropriate units."</em>
Solution:
First of all, we need to calculate the acceleration of the ball, given by
where
v = 40 m/s is the final velocity
u = 0 is the initial velocity
is the duration of the acceleration phase
Substituting,
Now we can find the force exerted on the ball by using Newton's second law:
where
m = 0.145 kg is the mass of the ball
a is the acceleration
Substituting,
Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed. Hope you find this helpful
Answer:
4.D.all of them are correct
5. B.Making observation
If the object is kept in between the principle axis and the focus but some what nearer to the focus then we will get the enlarge,erect,and real image.
In surface waves, particles of the medium undergo a circular motion. They are neither longitudinal nor transverse, for in longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction, respectively, relative to the direction of energy transport.
