Answer:
Renewable energy: Tidal, solar and wind
Non renewable energy: nuclear power
Explanation:
Renewable energy is any energy in which its source is always replenished or renewed.
While non renewable energy sources cannot be replenished or renewed immediately because of its limited availability of resources.
Most renewable energy sources are natural sources.
Solar, tidal and wind energy are renewable energy known as clean energy. While nuclear energy is a non renewable energy in which its source of energy is fuel ( uranium e.t.c)
We use the formula of the half-life to calculate for the remaining U-238 after 4.5 billion years. The formula is expressed as A = A₀ (1/2)^(t/h) where A is the final amount, A₀ is the initial amount of the substance, t is the time and h is the half-life of the substance wherein for U-238 h is equal to 4.47 billion years.
<span>A = A₀ (1/2)^(t/h)
</span>A = 50 (1/2)^(4.5 / 4.47)
A = 24.88 g
Answer:
Force on the spring will be equal to 10 N
Explanation:
We have given mass of the block m = 0.2 kg
Compression of the spring x = 0.01 m
Spring constant
It is not given what we have to find but i think we have to find force here
We know that force on the spring is given by
So the force on the spring will be 10 N
Because the sound vibrations traveled faster through the solid metal and slower through the gassy air.
