To solve this problem it is necessary to apply the concepts related to the Pressure which describes the amount of Force made on an area unit.
Its mathematical expression can be defined as

Where,
F= Force
A = Area
Our values are given as

With the diameter we can find the Area of the circular heel, that is


To find the force by weight we need to apply the Newton's second Law



Finally the pressure would be




Therefore the pressure that she exerts on the carpet sample is 6.788Mpa
Answer:they are converted to thermal energy
Explanation:
When they brake of a moving car is hit,the velocity would become zero, kinetic energy would be converted to thermal energy
Answer:
A
Explanation:
The distance of the object that reflected the sound wave can be calculated by knowing the speed of sound in water and the time interval between transmission and reception of ultrasound.20 Mar 2017
The answer for this question would be choice
B) FALSE because pitch is the quality of sound. *I take no credit for the image below I just found it off google.
Kinetic energy is due to motion and body has potential energy because of its position
so potential energy is firewoods and beans
kinetic energy is
moving water hiking and flames
