Anaphase, the shortest stage of mitosis
1 watt = 1 joule/sec
2,000 watts = 2,000 joules/sec
(2,000 joule/sec) x (120 sec)
= (2,000 x 120) (joule-sec/sec)
= 240,000 joules .
Answer:
d. Mass is the amount of matter in an object.
Explanation:
This is the exact definition of the word mass. My mom is a science teacher.
The relationship between resistance R and resistivity
is
where L is the length of the wire and A its cross section.
The radius of the wire is half the diameter:
and the cross section is
From the first equation, we can then find the length of the wire when
(copper resistivity:
)
The answer is C. Power is a measure of how much work is done, or how much energy is transferred, in a certain amount of time.
