The first shell has 2 in and the second shell has 8 in therefore ypuvwont need to add anymore :-) so the answer is 0
<span>The magnetic field produced by a current has three distinct characteristics. The field can be turned on or off, have its direction reversed, or have its strength changed.
Therefore the correct answer is D. All of the above</span>
Answer:
he correct answer is Traffic accidents.
Explanation:
Chinese researchers have developed a car that needs the power of brain to operate. It is said to be country's first car that is operated by the mind.

They believed that concentration is required only while changing the lane or during turns (changing the moving status of car).
I think C, because the Hydrosphere is the water part of earth and the atmosphere holds your clouds etc
Answer: 4.17 m
Explanation: According to the law of conservation of energy, the elastic potential energy of the elastic material is used in launching the mass hence giving the body it potential energy.
Elastic potential energy = kx²/2
Potential energy = mgh
Where m = mass of object = 0.24kg
g = acceleration due to gravity = 9.8 m/s²
h = height =?
k = spring constant = 850 N/m
x = compression = 31cm = 0.13m
kx²/2 = mgh
kx² = 2× mgh
850 ×(0.31)² = 2 × 9.8 × h
h = 850 × (0.31)²/ 2 × 9.8
h = 81.685 / 19.6
h = 4.17 m
