Control rods are used to slow down the reaction in the reactor core when the core becomes too hot. Please select the best answer

viktelen [127]

The best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.

<h3>What is a nuclear reactor?</h3>

A nuclear reactor, often known as an atomic pile, is a device that initiates and controls nuclear chain reactions or nuclear fusion processes.

Nuclear reactors are used in nuclear power plants to generate energy as well as in nuclear marine propulsion.

Control rods are employed in nuclear reactors because the processes that occur in a nuclear reactor are very exothermic.

As a result, when these control rods are infused into a nuclear reactor, they absorb neutrons and aid in the management of the chain reaction. As a result, the rate of the chain reaction is brought under control.

As a result, we may infer that the statement control rods are employed to slow down the reaction in the reactor core when it gets too hot is correct.

Hence the best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.

A marble rolls off a table from a height of 1.5 meters. Approximately how much time was the marble in the air?

sergij07 [2.7K]

Answer:

t = 0.55 s

Explanation:

Given that,

Height of the marble, h = 1.5 m

We need to find the time for which the marble is in air. Let the time is t. Using second equation of motion to find it as follows :

$h=ut+\dfrac{1}{2}at^2$

Here, u = 0 and a = g

$h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\cdot1.5}{9.8}}\\\\t=0.55\ s$

So, the marble is in air for 0.55 s. Hence, the correct option is (c).

A boat travels with a velocity equal to 14.0 meters per second, east in 6.15 seconds. What distance in meters does the boat trav

Y_Kistochka [10]

Answer:

Distance, d is 86.1 meters.

Explanation:

Given the following data;

Time, t = 6.15secs

Velocity = 14m/s

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

$Velocity = \frac{distance}{time}$

$V = \frac{d}{t}$

$d = Vt$

Substituting into the above equation;

$d = 14 * 6.15$

d = 86.1m

Hence, the distance traveled by the boat is 86.1 meters.
