Answer:
35 N to the right
Explanation:
When calculating net force when both forces are on the same side you add them when they are going against each other you subtract them.
To find power, you have to find work first.
Given :
F = 32kg —> 313.6 N
d = 0.1m
Work = Fd
= (313.6)(0.1)
= 31.36
P=W/t
=(31.36)/(0.83)
≈ 38 W
Answer:
The final velocity, , is gd.
Explanation:
The condition here is a free falling object. Thus from the third equation of motion under free fall, we have;
= + 2gs
where is the final velocity of the object, is the initial velocity of the object, g is the gravitational force and s is the height.
Since the object falls from a height of d, then = 0 m/s, and s = d.
So that;
= 0 + 2gd
= 2gd
= 2gd
When the distance is , = 0 m/s.
Then;
= 2g
= g x d
When the object falls through the height , then the final velocity is gd.
Acceleration due to gravity on that planet is half than that of om earth ~
that is ~
And it's weight is equal to ~
now, As we know ~
here ,
- g = Acceleration due to gravity on that planet = 4.9 m/s²
let find the mass of stone ~
Mass of the stone is 100 kg ~
I hope it helped
Answer:
Explanation:
The law of conservation of mass states that the mass of the elements at the beginning of the reaction(reactants) will equal the mass at the end of the reaction (product) .
In the chemical equation above,the total mass of the reactants is 80g(16+64) and the total mass of the products is also 80g(44+36).therefore the mass remained constant and that's how the equation represents the law of conservation of mass
