By using the scientific method
Answer:
14,653 J.
Explanation:
We know that,
Total mechanical energy is equal to the sum of all the potential and kinetic energies.
Given,
Kinetic energy when a car jumps off a ramp= 5000 J
Potential energy = 4685 J
Potential energy when the car lands= 4968 J
TME = 5000 + 4685 + 4968
= 14,653 J
Hence, the car's total mechanical engery is equal to 14,653 J.
Answer:
C
Explanation:
The sun has rotated causing the shadow to reflect.
Answer: Protons
Explanation: The atomic number is the number of protons that are in the nucleus of an atom. Each element on the periodic table is defined by the number of protons. In other words, the protons/atomic number determines what element it is. Protons carry a positive charge.
