Explanation:
The solar fare consists of bright light that occurs in various wavelengths and is observed at the surface. They are not as strong as compared to the coronal mass ejection or CME. The solar fares consist of 10²² joules, while the plasma is ejected from the solar corona and can be clearly seen from a distance. The Solar flares represent an atmospheric disturbance and plasms are the medium for the growth and development of solar flare and lead to solar activity.URGENT PLEASE HELP!!!! GIVING BRAINLIEST!!

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
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.
Point P is located 1.7 m from fixed point charge q. The electric field Ē at point P is 8.6 x
10-2 N/C, directed away from the point charge. What is the magnitude of q? Let the
electrostatic constant k = 8.99 x 10°N • m²/C2.
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
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?
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.

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
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.

Which do you think requires more Work, lifting a 100 N load a vertical distance of 2 m or lifting a 10 N load a vertical distance of 4 m?
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
or
F = 10 N
D = 4 m
Solution
Work = 100 * 2
Work = 200 Joules
Work = 10 * 4
Work = 40 J

what factors affect electrostatic force?
Answer:
The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.

Camina con otro compañero, al mismo tiempo y al mismo paso. Quién se mueve tú o tu compañero? Razona tu respuesta
Answer:
Fricción.
Explicación:
Caminando con otro compañero al mismo tiempo y al mismo ritmo, el movimiento se produce debido a la fricción del suelo y la suela de los zapatos porque la fricción es la fuerza que ayuda en el movimiento de los objetos de un lugar a otro. Si no hay fricción entre el suelo y la suela de los zapatos, no podemos dar un paso por lo que podemos decir que la fricción nos mueve hacia adelante.

A 50 kg boy jumps off the front of a 1.5 kg skateboard moving forward. Find the skateboard's velocity
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?
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

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
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.
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.
