Answer:
44J
Explanation:
Given parameters:
Mass of rock = 0.22kg
Initial velocity = 20m/s
Distance moved = 10m
Unknown:
Initial kinetic energy of the rock = ?
Solution:
To solve this problem, we need to understand that kinetic energy is the energy due to the motion of a body.
It is mathematically expressed as;
Kinetic energy = m v²
m is the mass
v is the velocity
Kinetic energy = x 0.22 x 20² = 44J
C) voltage is a force that pushes charge along
34 degrees Fahrenheit is equal to 1.11 Celsius. There is a simple formula for calculating it or you can use a converter and see the results
The element is a resistor, so some of the electrical energy flowing through the heating element is converted to thermal energy.
