An 8 Newton wooden block slides across a horizontal wooden floor at constant velocity. What is the magi notice of the force of k
1 answer:
Answer:
The force of kinetic friction between the block and the floor is 2.4 N
Explanation:
The given parameters are;
The weight of the block = 8 Newtons
The velocity of the block = Constant velocity
Taking the kinetic friction for wood, = 0.3, we have;
The normal reaction of the block on horizontal ground, N = The weight of the block = 8 N
The force of kinetic friction between , =
× N
Therefore, we have;
The force of kinetic friction between the block and the floor, = 0.3 × 8 N = 2.4 N.

<h3>What is a capacitor?</h3>A capacitor is a device that can store electrical energy. It is a two-conductor configuration separated by an insulating medium that carries charges of equal size and opposite sign.
An electric insulator or vacuum, such as glass, paper, air, or a semi-conductor termed a dielectric, can be used as the non-conductive zone.
The given data in the problem is;
C is the capicitence of capicitor= 0. 40 µF
V is the voltage = 9. 0 V
Q is a charge on each plate of the capacitor=?µC.
The formula for the capacitor is given as;
Hence the charge on each plate of the capacitor will be 3.6 µC.

Answer: 150 m
Explanation:
velocity = 22 m/s
t = 6.8 s
velocity =
distance = velocity × time
= 22 × 6.8
= 149.6 m
≈ 150 m
