Answer:
The efficiency is never 100% because some energy will either escape through theromal lose or actualy been lost throughout the process of operation. Not 100% of any energy could be converted into moving anything.
Explanation:
Answer: 0.002 newtons
===================================================
Work Shown:
I'm assuming you meant to write "at 20 m/s^2" at the end. If so, then,
0.10 grams = 0.10/1000 = 0.0001 kg
m = 0.0001 kg = mass
a = 20 m/s^2 = acceleration
F = ma .... newton's second law
F = 0.0001*20
F = 0.002
The force required is 0.002 newtons
Answer:
<em>The Sun produces energy by the process of nuclear fusion. Nuclear fusion occurs when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures. Nuclear fusion occurs in the core of the Sun when hydrogen atoms combine to form helium atoms.</em>

The mass of whole blood is 0.51 kg.
Given data:
The dimensions of container is 125 mmx 110 mm x 35 mm.
From the chart, the density of whole blood at 37 C is,
The volume of container can be calculated as,
The mass of whole blood will be,
Thus, the mass of whole blood is 0.51 kg.
A geologist is studying rock layers in an old river bed, and he finds a fossil of a fish and a horsetail rush in the same rock layer. According to the law of faunal and floral succession, the geologist can assume that the rock containing the fossils may date back as far as the <span>Devonian period</span>.
