To calculate the acceleration of the wooden block, we use the expression F=ma where F is the force applied, m is the mass of the object and a is the acceleration. We calculate as follows:
F = ma
4.9 = 0.5a
a = 9.8
Hope this answers the question. Have a nice day.
Had to look for the options and here is my answer. What happens when the fluid discharge of an air-operated reciprocating pump is shut, this will cause the pump to OVERSTROKE. Overstroke happens when the engine is switching in a normally-closed manner.
Answer: C.
Explanation:
i choose B and got it wrong it told me the answer after on edge.
Answer:
The expression of gravitational field due to mass
at a distance 
Explanation:
We have given mass is 
Distance of the point where we have to find the gravitational field is 
Gravitational constant G
We have to find the gravitational filed
Gravitational field is given by 
This will be the expression of gravitational field due to mass
at a distance 
Answer: 2R
Explanation:
Here the person travels пR distance. We know that the circumference of a circle is 2πR. So your imaginated person has traveled the distance which is half of the circumference of the circle. And this distance is equal to its diameter. We know that diameter of a circle is two times larger than the radius. So the person's displacement is two times of the radius, means 2R. [Here 'R' means the radius of the circle]
