Answer:
the safe's coefficient of kinetic friction on the bank floor is
Explanation:
GIven that:
Bonnie and Clyde are sliding a 325 kg bank safe across the floor to their getaway car.
So ,let assume they are sliding the bank safe on an horizontal direction
Clyde → Δ(bank safe) → Bonnie
Also; from the above representation; let not forget that the friction force is acting in the opposite direction ←
where;
=
The safe slides with a constant speed
If Clyde pushes from behind with 377 N of force while Bonnie pulls forward on a rope with 353 N of force.
Thus; since the safe slides with a constant speed if the two conditions are met; then the net force acting on the slide will be equal to zero.
SO;
Since the net force acting on the slide will be equal to zero.
Then;
Also; let and
Then;
where;
Then;
Thus; the safe's coefficient of kinetic friction on the bank floor is
Answer:
Increases
Explanation:
Higher current Higher resistance
Directly proportianal to each other
The compound name for box 1 should be sodium chloride.
The type of bond for box 3 should be covalent.
Answer:
306500 N/C
Explanation:
The magnitude of an electric field around a single charge is calculated with this equation:
With ε0 = 8.85*10^-12 C^2/(N*m^2)
Then:
E(0.89) = 306500 N/C
