Why are very high temperatures and pressures required for fusion to occur?
to generate the neutrons that are needed to break the nuclei
to overcome the repulsion between the protons in the nuclei that join
to maintain the proper conditions to keep the chain reaction going
to keep the uranium fuel separate from the control rods
Answers
Answer:
so as to over come the repulsion between the protons in nuclei that join
Explanation:
it requires high temperature so that the nucleus starts moving at rapid speed which in turn increases their kinetic
In nuclear reactions, very high temperatures and pressures required for fusion to occur so as to to overcome the repulsion between the protons in the nuclei that join.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Ted lifts a 10N weight at a height of 1.5 m in 1 second. Johnny lifts a 10N weight at a height of 1.5 m in 2 second. Which statements are correct? A. Johnny and Ted did the same amount of work B. Ted did more work C. Johnny and Ted expanded the same power D. Ted expanded more power E Johnny did more work F. Johnny expanded more power
Answers
Answer:
he affirmations the correct ones are: A and D
Explanation:
To find out which expressions are correct, let's calculate the work and power done by each person
the expression for work is W = F and
the expression for power is P = W / t
In this case the work is positive because the beast is in the same direction of displacement.
Ted
W₁ = 10 1.5
W₁ = 15 J
P₁ = 15/1
P₁ = 15 w
Johnny
the job
W₂ = 10 1.5
W₂ = 15 J
the potential
P₂ = 15/2
P₂ = 7.5 w
therefore we see that the work of both is the same, but Ted developed twice as much power as Johnny
when resisting the affirmations the correct ones are: A and D

A)This part controls the amount of light entering the eyes. A= Iris B= Pupil Give reason for your answer.
Answers
Answer:
Iris
Explanation:
Iris can be described as a part of the eyes which regulates the amount of light that enters the eye. The iris is made up of various muscles that control the size of the pupil
When a person is in a well-lighted room, the iris decreases the size of the pupil so that a low amount or medium amount of light is absorbed into the pupil. Also when an individual steps into a dark room the iris increases the size of the pupil so that a high amount of light penetrates the pupil.
Hence without the iris the amount of light that enters the eye cannot be controlled.

Two people travel from Columbus to Cleveland, one by car at an average velocity of 90km/h, and one by plane at an average velocity of 300km/h. Can their displacements be equal
Answers
Answer:
Explanation:
Yes , their displacement may be equal .
Suppose the displacement is AB where A is starting point and B is end point .
The car is covering the distance AB by going from A to B on straight line . On the other hand plane goes from A to C , then from C to D and then from D to B . In this way plane reaches B from A on a different path which is longer than path of the car . In the second case also displacement of plane is AB . In the second case distance covered is longer but displacement is same that is AB .
Point P is located 1.7 m from fixed point charge q. The electric field Ē at point P is 8.6 x

O
A. 2.8 10-11 C
0
B. 4.8 * 10-11 C
O.C. -4.8 x 10-11 C
D. 1.5 x 10-10
Answers
Answer:
2.8 × 10^-11 C
Explanation:
The computation of the magnitude of q is shown below;
The electric field at point P because of point charge Q is provided by,
E = 8.6 × 10^-2 N/C
And, the separation between charge Q and P is r = 1.7m
Now According to the Coulomb's law,
E = kQ ÷ r²
8.6 × 10^-2 = 9 × 10^9 × Q ÷ (1.7)²
8.6 × 10^-2 × 2.89 ÷ 9 × 10^9 = Q
Q = (8.6 × 2.89 ÷ 9) × 10^-11
Q = 2.76 × 10^-11 C
= 2.8 × 10^-11 C

If a car has a velocity of 85 km/hr, how long will it take to accelerate to 45 km/hr if the acceleration is -3 km/hr/sec?
Answers
Answer:
Time, t = 13.34 seconds.
Explanation:
Given the following data;
Initial velocity, u = 85km/hr to meters per seconds = 85*1000/3600 = 23.61 m/s
Final velocity, v = 45km/hr to meters per seconds = 45*1000/3600 = 12.5 m/s
Acceleration, a = -3 km/hr/sec to meters per seconds square = -3*1000/3600 = -0.833m/s²
To find the time;
Acceleration = (v - u)/t
-0.833 = (12.5 - 23.61)/t
-0.833t = -11.11
t = 11.11/0.833
Time, t = 13.34 seconds.

Answers
Answer:
Lifting 100 N 2 meters is much more work.
Explanation:
Remark
The formula is F * d = W
Givens
F = 100 N
D = 2 m

F = 10 N
D = 4 m
Solution
Work = 100 * 2
Work = 200 Joules
Work = 10 * 4
Work = 40 J

If a vehicle accelerating at 2.7 m/s2what is it's velocity at 20 meters 12.63m/s,1.03m/s,10.39m/s,6.39m/s
Answers
Answer:
The final velocity of the vehicle is 10.39 m/s.
Explanation:
Given;
acceleration of the vehicle, a = 2.7 m/s²
distance moved by the vehicle, d = 20 m
The final velocity of the vehicle is calculated using the following kinematic equation;
v² = u² + 2ah
v² = 0 + 2 x 2.7 x 20
v² = 108
v = √108
v = 10.39 m/s
Therefore, the final velocity of the vehicle is 10.39 m/s.

immediately after the boy jumps, assuming that the skateboard's initial velocity is 3.5 m/s and the boy's
velocity when jumping off the front is 5 m/s?
Answers
Answer:
The speed is 1.35 m/s
Explanation:
(m1+m2) vi= m1+m2v2
(50+1.5) (3.5)=50 (5+v2) +1.5 v2
180.25= 250+ 51.5 v2
180.25- 250+ 51.5 v2
-69.75= 51.5 v2
v2= -1.35 m
Why did you need a permanent magnet? What do you think would happen if you increased the
number of permanent magnets? (dc motor)
Answers
Permanent magnets are important for their industrial uses especially when it comes to power generation and electric motors. The induction process for turbines and generators needs permanent magnets to turn mechanical motion into energy.
Exposing magnetized magnets to opposing external fields produces a demagnetizing effect. This effect is most apparent in permanent magnet materials having a non-linear demagnetization curve, such as Alnico. ... Other factors such as SHOCK and VIBRATION have very little effect on today's permanent magnet materials.
