Answer:
the first one is Primary
the second one I think it's Mature but I don't know
Answer:
Explanation:
In order to solve this problem we need to make a free body diagram of the book and the forces that interact on it. In the picture below you can see the free body diagram with these forces.
The person holding the book is compressing it with his hands, thus exerting a couple of forces of equal magnitude and opposite direction with value F.
Now the key to solving this problem is to analyze the equilibrium condition (Newton's third law) on the x & y axes.
To find the weight of the book we simply multiply the mass of the book by gravity.
W = m*g
W = 1.3[kg] * 9.81[m/s^2]
W = 12.75 [N]
It runs slower <span>as gravity is lower so acceleration due to gravity is smaller</span>
Yes
momentum=mass x velocity
or you could rearrange the formula to find velocity = momentum/mass (you get this by dividing both sides in the original equation by mass)
you could also get that mass= momentum/velocity (you get this by rearranging both sides of the original equation by velocity)
