The energy chain diagram in this case is chemical energy >> energy conversion >> motion (kinetic) energy + thermal energy.
<h3>What is an energy chain diagram?</h3>
An energy chain diagram is a graphic representation indicating the conversion between different types of energies.
Kinetic energy is a type of motion (movement) energy generated by using potential (stored) energy.
Chemical energy (in this case, the fuel of the car) is a type of energy that is stored to perform work.

Answer:
Electrostatic Force...or a non-contact force
Explanation:
I may be wrong but does it mean it was revent? because i know shortly after someone dies your body becomes fully stiff so maybe it was recent and it's in the process off stiffening up
Answer:
The mass of the man is 71 kg
Explanation:
Given;
kinetic energy of the man, K.E = 887.5 J
velocity of the man, v = 5 m/s
The mass of the man is calculated as follows;
K.E = ¹/₂mv²
where;
m is the mass of the man
2K.E = mv²
m = 2K.E / v²
m = (2 x 887.5) / (5)²
m = 71 kg
Therefore, the mass of the man is 71 kg
Answer:
1.58 W
Explanation:
Since the sound spreads uniformly in all directions, it must be in a form of a circle with radius of 12 m. So the area of the circle is
From the intensity of the sound we can calculate the power at 12 m
