Nuclear energy is EXTREMELY ecofriendly, punching down any fossil fuels and even wind energy. It also is reliable, and has low emissions. However, nuclear energy is somewhat expensive and can go wrong, being dangerous to the environment and people. Along with this, uranium is finite and radioactive waste disposal is really bad.
use F = ma
F : force m : mass a : acceleration
so
f = 5kg * 20 m/s2 = 100 N
Answer:
4÷3
Explanation:
40 miles and 1 hour equals 30 minutes so 40÷ 30 gives 4÷3
Answer:
the distance should be changed by a factor of √2
Explanation:
The attractive force between the couples can be given by Newton's Law of Gravitation:
where,
F = Attractive Force
G = Universal Gravitational Constant
m₁ = mass of the first person
m₂ = mass of the second person
r = distance between them
Now, if we want to halve the force without changing masses, hen:
<u></u>
<u>Hence, it is clear that the distance should be changed by a factor of √2</u>
Because the less dense magma is lighter so it floats to the top.
