In a nuclear power plant, the nuclear reaction is kept from going critical by keeping the rate of reaction safe. How do the cont

rol rods figure into this?
A. The controls rods absorb the excess heat produced in the reaction.
B. The controls rods absorb excess neutrons, keeping them from causing too many uranium atoms to split too quickly.
C. The control rods provide additional neutrons to keep the reaction going.
D. The control rods absorb excess uranium atoms so that the reaction doesn't happen too quickly.

Correct answer is B

Explanation:

Control rods in Nuclear reactor:

During nuclear reaction when a heavy nucleus break up into two light nuclei that time neutron are release and these neutrons further break up other nucleus which release more neutrons which lead to a chain reaction. the nuclear reaction is kept from going critical by keeping the rate of reaction safe by using control rods. Controls rods absorb excess neutrons, keeping them from causing too many uranium atoms to split too quickly.

A hockey puck with mass 0.3 kg is shot across an ice-covered pond. Before the hockey puck was hit, the puck was at rest. After t
JulsSmile [24]

Answer:

The net friction force is 8.01 N

Explanation:

Net friction force = mass of hockey puck × acceleration

From the equations of motion

v^2 = u^2 + 2as

v = 40 m/s

u = 0 m/s (puck was initially at rest)

s = 30 m

40^2 = 0^2 + 2×a×30

60a = 1600

a = 1600/60 = 26.7 m/s^2

The acceleration of the puck is 26.7 m/s^2

Net friction force = 0.3 × 26.7 = 8.01 N

4. How does a molecule differ from an atom
tia_tia [17]

Answer:

Explanation:

In a molecule, atoms are bonded together by single, double, or triple bonds. An atom has a nucleus surrounded by electrons. ... So another difference between atoms and molecules is that when similar atoms combine together in varying numbers, molecules of different properties can be formed.

A student starts a food fight by throwing a 0.5 kg burrito at some girl he likes. He throws it kind-of hard so he accelerates it
Elenna [48]

Explanation:

m = mass of burrito thrown by the student = 0.5 kg

a = acceleration of the burrito thrown by the student = 3 m/s²

F = force applied by the student on the burrito = ?

According to newton's second law , the net force on an object is the product of its mass and acceleration. it is given as

F = ma

inserting the values

F = (0.5) (3)

F = 1.5 N

hence the net force on the burrito comes out to be 1.5 N

How can Newton's laws be applied to protect a smartphone screen during a collision?
Sonja [21]

smartphones break due to forces acting on the material.

force causes material to deform.

material is often brittle and cracks due to a limit on hardness / electricity in screens.

newton's 2nd law states

force = DV / DT

to help phones we must slow down change in momentum to reduce the force

thus we must use some form of damping in the form of a case .

the case is typically able to deform and rubber is elastic converting the kinetic energy to heat as it deforms instead of transferring it through the screen.

therefore the change in velocity occurs over a longer time. therefore the impulse decreases
