Answer:
B. energy
Explanation:
A vector has direction.
Energy does not have a direction.
Answer:
B
This is because frictional energy is similar to thermal energy in a system. Therefore the thermal energy produced is equal to
Answer:
The component of block weight parallel to the plane, Wₓ = W cosθ
Explanation:
Let the weight of the block due to gravitation is W
The direction of the weight is vertically down
Let θ be the angle formed with the vertical weight of the block and the incline.
Taking two components of weight one along the vertical weight and another component perpendicular to it.
Then the component `of weight long the parallel of the plane is
Wₓ = W cosθ
The answer is 2.14 kW.
You get this by dividing the outside number (110) by all the resistors and then adding the values together.
I would say C but I’m not complete sore
