Answer:
True
Explanation:
The cooling system of a vehicle is basically the radiator system. In the radiator, the coolant is a mixture of water and chemical. The chemical prevents corrosion in the radiator. The coolant helps in absorbing heat from the engine by flowing through passages with the help of a water pump and this flow is monitored by the a thermostat.
Terminal velocity is the point when an accelerating object reaches a constant speed. When an object is in free fall on earth, this happens due to the drag force of the atmosphere that pushes up on the object.
If the earth had no atmosphere, the object would keep accelerating and never reach terminal velocity due to the lack of air drag.
Since you provide no options, here are some role of the foresters :
- they develop sustainable forest practice
- They asses timber Quality
- They make sure that all harvesting activities followed the law's regulation
- They plan and supervise forestry project
your answer might be the one that isn't included above
D) It isn't accelerating
This is because if both sides are pushing with the exact same force, than one force is not overpowering the other, therefor the wheelbarrow would not be moving.
Answer:
Part a)
Part b)
Part C)
Part d)
Due to large magnitude of friction between road and the car the momentum conservation may not be valid here as momentum conservation is valid only when external force on the system is zero.
Explanation:
Part a)
As we know that car A moves by distance 6.1 m after collision under the frictional force
so the deceleration due to friction is given as
now we will have
Part b)
Similarly for car B the distance of stop is given as 4.4 m
so we will have
Part C)
By momentum conservation we will have
Part d)
Due to large magnitude of friction between road and the car the momentum conservation may not be valid here as momentum conservation is valid only when external force on the system is zero.
