Answer:
koh
Explanation:
it is a basic substance that reacts with the lipids on your fingers, as soon as you touch it, to form soap
<span>There are Billions and billions of galaxies in the universe containing Trillions and trillions of stars in each galaxy.</span>
<span>Net charge of the object = 0.500 ÎĽc
The charge of electron = -1.602 x 10^-19 C
Calculating the net change in the number of electrons = 0.5 x 10^-6 / -1.602 x 10^-19 = - 3.12 x 10^12
The negative sign implies the number of electrons that needs to be removed that is 3.12 x 10^12</span>
The net force is (40 Newtons) (down the road).
But 40 Newtons is not going to move a piano very enthusiastically.
Answer:
471392.4 N
Explanation:
From the question,
Just before contact with the beam,
mgh = Fd.................... Equation 1
Where m = mass of the beam, g = acceleration due to gravity, h = height. F = average Force on the beam, d = distance.
make f the subject of the equation
F = mgh/d................ Equation 2
Given: m = 1900 kg, h = 4 m, d = 15.8 = 0.158 m
Constant: g = 9.8 m/s²
Substitute into equation 2
F = 1900(4)(9.8)/0.158
F = 471392.4 N
