Hi there!
Since the car is not accelerating in the vertical direction, the only net force acting on the car is in the horizontal direction.
This is the force due to friction, which is also providing the centripetal force. So:
m = mass (kg)
v = velocity (m/s)
r = radius (m)
Plug in the given values:
The answer is A. Weathering,erosion, and then transportation
Instead of washing vegetables in running water, fill a bowl of water and wash inside the bowl.
bad handwriting tho........... hope u understand
The maximum force of static friction is the product of normal force (P) and the coefficient of static friction (c). In a flat surface, normal force is equal to the weight (W) of the body.
P = W = mass x acceleration due to gravity
P = (0.3 kg) x (9.8 m/s²) = 2.94 kg m/s² = 2.94 N
Solving for the static friction force (F),
F = P x c
F = (2.94 N) x 0.6 = 1.794 N
Therefore, the maximum force of static friction is 1.794 N.
