Answer:
(you can use my exact words) The length and thickness would make it so that the electrons move differently than they would a shorter and thinner wire because with the wire being longer the electrons would have a longer trip and with the wire being thicker the electrons would be more spread out and move be able to move more freely
Answer:
P = m g v
Explanation:
Power is defined as the relationship between work and time
P = W / t
The work is defined by the scalar product of the force and the displacement, in the case of a drop falling the vertical force and the displacement has the same direction, therefore the angle between them is zero and the cosines of zero is one (cos 0 = 1)
W = F y
the gravitational force is proportional to the weight of the drop (F = mg)
W = mg y
we substitute
P = m g y / t
the terminal velocity of the drop is constant
P = m g v
Answer:
So where the red square is located it will be 90 °
And another will be 180-90-57= X
The maximum possible force of static friction between two surfaces is given by:
F = μN
F = max friction force, μ = coefficient of static friction, N = normal force
The normal force N equals the object's weight:
N = mg
m = mass, g = gravitational acceleration
Make a substitution:
F = μmg
Given values:
F = 500N, m = 100kg, g = 9.8m/s²
Plug in and solve for μ:
500 = μ(100)(9.8)
μ = 0.51
Can you please tell what "it" is?
