Determine whether the following actions cause the fission reaction in the reactor to speed up or slow down.

Physics
1 answer:
Alik [6]3 years ago
4 0

Answer:

option B and C

Explanation:

Control rod are used to regulate the nuclear reactor.

When you insert control rod in the reactor it slows down the nuclear fission inside the reactor and the energy produced in the reactor will be less.

When you remove control road from the reactor the nuclear fission increase inside the reactor and the energy production is high.

Control rod consist of boron, boron absorb the neutron which help to control the nuclear fission.

Hence, the correct answer is option B and C

Consider a particle with initial velocity v⃗ that has magnitude 12.0 m/s and is directed 60.0 degrees above the negative x axis.
lina2011 [118]

Answer:

-6.0 m/s, 10.4 m/s

Explanation:

To find the x- and y- components, we have to apply the formulas:

v_x = v cos \theta

v_y = v sin \theta

where

v = 12.0 m/s is the magnitude of the vector

\theta is the angle between the direction of the vector and the positive x-axis

Here, the angle given is the angle above the negative x-axis; this means that the angle with respect to the positive x-axis is

\theta=180^{\circ} - 60^{\circ} = 120^{\circ}

So, the two components are:

v_x = (12.0 m/s) cos 120^{\circ}=-6.0 m/s

v_y = (12.0 m/s) sin 120^{\circ}=10.4 m/s

Jenny and Alyssa are members of the cross-country team. On a training run, Jenny starts off and runs at a constant 3.8 m/s. Alys
guapka [62]

Answer:

285 seconds

Explanation:

Jenny speed is 3.8 m/s

Alyssa speed in 4.0 m/s

Alyssa starts after 15 seconds

Find the distance covered by Jenny, when Alyssa starts

Distance=Speed*time

Distance covered by Jenny in 15 seconds= 3.8×15=57m

Relative speed of the two members heading same direction will be;

4.0m/s-3.8m/s=0.2m/s

To find the time Alyssa catch up with Jenny you divide the distance to be covered by Alyssa by the relative speed of the two

Distance=57m, relative speed=0.2m/s  t=57/0.2 =285 seconds

=4.75 minutes
