Power is defined as Work / Time.
With this formula, we can solve.
As of now, we are looking for the power
P=
We have 2,000J of work and 80s (simplified into seconds).
2,000 / 80
Rewrite our transitions into an equation.
P = 2,000 / 80
Divide 2,000 by 80.
2,000 / 80 = 25.
Your answer is:
25W (W is the unit for Watts)
I hope this helps!
Answer:
thermosphere(80 - 480 km from Earth's surface)
Explanation:
characteristics
- cloudless and free of water vapour
- the phenomenon of aurora is seen in this layer
- the bottom part of the thermosphere is known as the ionosphere
- the ionosphere has very high temperatures due to the presence of charged particles or ions. The ions function as a reflector of electromagnetic waves in long distance telecommunications.
Answer: A, B, and C are correct.
Polar attractions are (a) forces between atoms of partial charges.(b) weaker than covalent bond.(c) they are numerous.
Explanation:
Polar attractions take place between atoms with partial charges. They are weaker than covalent bond and numerous of them occur in the living cells. They can form between H and other electronegative atoms like oxygen provided they have strong partial charges.
B.
Deforestation affects ecosystems on land. there are no forests underwater
