Given :
Mass of person, m = 81 kg.
Area of high heal, A = 3.5 cm² = 0.00035 m².
To Find :
The pressure applied by the heal on the ground.
Solution :
We know, pressure is given by :
Hence, this is the required solution.
The frequency and period of any wave are reciprocals.
Frequency = 1/period and Period = 1/frequency .
That means that the product of (frequency) times (period) of any wave is always the same. The product is always ' 1 ', with no unit.
It will depend on the frictional force involved in the two. I think it will take more force in sled.
Answer:
What forces act on a marble rolling down a ramp?
Answer: Gravity acts vertically downward. A normal force acts from the ruler toward the marble/ball in a direction that is perpendicular to the plane of the ruler. Friction acts in the direction opposite to which the marble/ball is moving. ... Friction slows down the marble/ball.
