Answer:

Control rods

Explanation:

Control rods is unique to nuclear power plants as they are mainly used in nuclear reactors to stabilize the rate of fission of plutonium or uranium. They are usually composed of chemical elements such as cadmium, silver, boron, and indium.

Answer:

Control rods

Explanation:

Control rods are used to control the rate of nuclear chain reaction in nuclear reactors. The reactivity of the nuclear reactor is greatly affected by the distance of control rods inserted and number of control rods inserted. Control rods control the rate of fission of uranium, etc., in a nuclear reactor

How long with it take an object to accelerate from 6 m/s to 13 m/s at a rate of 1.4<br> m/s2. *

Blizzard [7]

Explanation:

hello,

a = ( v - u ) / t

where u is the initial velocity.

and v is the final velocity.

t represents time,

and a represents acceleration.

in this case,

a = 1.4 m/s²

u = 6 m/s

v = 13 m/s

hence,

1.4 = (13 - 6)/t

1.4t = 7

t = 7/1.4

t = 5 s

thank you!

Which of the following is true of children with chronic illness? a.) They are all eligible to recievie special education service

ss7ja [257]

Answer:

c.) Their eligibility for social education services depends on whether their conditions adversely affect their educational functioning.

Explanation:

Chronic Illness is a human health condition in which a particular (or number of) illness is persistent in the body and the effects on the body are long-lasting and are often resistant to treatment. The word chronic is usually used when the disease/illness/sickness and its effects stay in the body for more than three months.

The likeliest answer from the options given is option C because before social education services are given, it has to be decided if their health condition adversely affects their education.

A raccoon falls out of a tree from a height of 1.2. Which equation can you use to calculate the time it takes for the raccoon to

Inga [223]

Answer:

$t=\sqrt{\frac{2S}{g}}=\sqrt{\frac{2 \cdot 1.2 m}{9.81 m/s^2}}=0.50 s$

Explanation:

The equation that we can use to calculate the time it takes for the raccoon to fall to the ground is:

$t=\frac{2S}{g}$

where S=1.2 m is the height of the tree and g=9.81 m/s^2 is the acceleration due to gravity. This equation is derived from the equation of the distance in a uniformly accelerated motion, which is given by

$S=S_0 + v_0 t + \frac{1}{2}at^2$

where S0 is the initial position, v0 is the initial velocity and t the time. In this problem, we can put S0=0 (we can take the initial position as the initial position of the raccoon) and v0=0 (the raccoon starts from rest), so the equation becomes

$S=\frac{1}{2}at^2$

and since the motion is a free fall, the acceleration is equal to the acceleration of gravity, so a=g:

$S=\frac{1}{2}gt^2$

And by re-arranging it, we find

$t=\sqrt{\frac{2S}{g}}$

By substituting numbers, we find

$t=\sqrt{\frac{2S}{g}}=\sqrt{\frac{2 \cdot 1.2 m}{9.81 m/s^2}}=0.50 s$
