Hello! Force = mass * acceleration. We can go ahead and eliminate A and B, because those answers are too small. We can multiply 4.5 (mass) * 9 (acceleration) to find the amount of force needed. 4.5 * 9 is 40.5.The amount of force needed is 40.5 N. The answer is C: 40.5 N.
Revolution means orbiting around another body.

Answer:
Part a)
a = -9.81 m/s/s
Part b)
v = 0
Part c)
v = 9.81 m/s
Part d)
Explanation:
Part a)
During the motion of ball it will have only gravitational force on the ball
so here the acceleration of the ball is only due to gravity
so it is given as
Part b)
As we know that ball is moving against the gravity
so here the velocity of ball will keep on decreasing as the ball moves upwards
so at the highest point of the motion of the ball the speed of ball reduce to zero
Part c)
We know that the total time taken by the ball to come back to the initial position is T = 2 s
so in this time displacement of the ball will be zero
Part d)
at the maximum height position we know that the final speed will be zero
so we will have
here we have
Answer:
option A
Explanation:
The meteor shower is the celestial activity in which meteors are observed to radiate or originate from one point.
Meteors are nothing but dust or ice from the trails of comets. Most of the meteors are less than the size of the sand particle.
We will see comet shower when we earth will cross the orbit of the comet.
Hence, the correct answer is option A
1.Adaptation is the action or process of adapting or being adapted.
2. a movie, television drama, or stage play that has been adapted from a written work, typically a novel.
3. a change or the process of change by which an organism or species becomes better suited to its environment.
Hope I helped! :P
