Answer:
E) The object achieves its maximum speed at approximately x=3m.
Explanation:
Since the object is moving in gravitational field
potential energy + kinetic energy = constant = 14 J
At x = 3 m , potential energy is minimum that is zero
kinetic energy will be maximum .
Kinetic energy = 14 - 0 = 14 J
Hence option ( E ) is the answer.
Answer:
option C.
Explanation:
The correct answer is option C.
The owner is at the top of the organizational pyramid he owns the organization and all the investment is done by the owner.
Strategic teams do all the strategy related work like how to increase production, decrease the losses, how to increase the quality, etc.
Operational team deals with the work which is related to taking work, assigning work and giving the result to the higher authority.
hence, the work of Andy Benton matches with the duties of the Operation team
The acceleration of the ball is 1.27 X 10⁵ m/s²
The Newtons second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Given,
Mass = 145 kg
Force = 18,400 N
We need to calculate the acceleration
Using formula of acceleration(a)
a = F/m where F= force and m= mass
Put the values in the formula,
a = 18,400/(145 X 10⁻³) = 1.27 X 10⁵ m/s²
Therefor, the acceleration of the ball is 1.27 X 10⁵ m/s².

The correct answer to the question is: C) They control the rate of reaction.
EXPLANATION:
The control rod plays a crucial role in nuclear reaction. The main function of the control rod is to control the rate of reaction.
The nuclear chain reaction becomes uncontrolled when number of neutrons are not controlled. It is so because each decay of radioactive uranium or plutonium produces three extra neutrons which again decay the radioactive sample at a faster rate.
The control rods are made up of boron,indium and cadmium like substances. They absorb the thermal neutrons generated in each decay of radioactive specimen. In this way, they control the rate of reaction.
Separation is the propagation method in which these natural structures are simply removed from the parent plant and planted to grow on their own. When one of these structures is cut into sections that will then grow into a new plant the method is referred to as division.
