The correct answer to the question is : Photosphere i.e it is the region whose temperature is 6000 degree celsius.
EXPLANATION:
The Sun has many regions starting from photosphere to central core. Different regions of the sun has different temperature.
The temperature of the sun is due to the fusion occurring inside it. The core temperature is immense due to the gravitational attraction which produces more heat there. Gradually the temperature decreases as we move away from the sun core.
As per the question, the temperature is given as 6000 degree celsius.
The region of the sun which corresponds to this temperature is photosphere. The temperature of photosphere varies from 5500 degree celsius to 7500 degree celsius. The temperature of sunspots found in the sun may be lower than the average temperature of the photosphere.
Hence, the correct answer is Photosphere.
Answer:
the work done on the car by the applied force is 75 J.
Explanation:
Given;
initial velocity of the car, v = 4 m/s
applied force in opposite direction, F = 5N
initial position of the car, x₀ = 5 m
final position of the car, x₁ = 20 m
displacement of the car, Δx = x₁ - x₀ = 20 m - 5m
= 15 m
The work done on the car by the applied force is calculated as follows;
W = F.Δx
W = 5 x 15
W = 75 J
Therefore, the work done on the car by the applied force is 75 J.

Explanation:
Newton's First Law ,
F = ma
a = m/F
a = 68 / 59
a = 1.15 m/s2
b) of less than 600 N is the truck is slowing down
c) equal to 600 N only if the truck is moving at constant velocity
d) equal to 600 N no matter what the acceleration of the truck
e) greater than 600 N if the truck is accelerating
A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force equal to 600 N no matter what the acceleration of the truck. Option c is correct.
According to Newton's third law of motion, every action has an equal and opposite reaction. As well as the action and reaction are always acted in pairs.
Based on the law of action-reaction,
A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force greater than 600 N if the truck is accelerating.
If the truck is moving at constant velocity the acceleration is zero resulting in no force exerted by the truck on the trailer
The force by which the transport truck pulls on a trailer is equal to the force by which the trailer pulls the truck.
F₁ is the force by which the transport truck pulls on a trailer
F₂ is the force by which the trailer pulls the truck
F₁=F₂
A 600N [E] pulling force is applied by a transport vehicle to a trailer. Regardless of the transport truck's acceleration, the trailer pulls on it with a force of 600 N.
