Answer:
4.2s
Explanation:
Given parameters:
Power = 2190W
Mass of box = 1.47 x 10⁴g
distance = 6.34 x 10⁴mm
Unknown:
Time = ?
Solution:
Power is the rate at which work is done;
Mathematically;
Power =
Time =
Work done = weight x height
convert mass to kg;
100g = 1kg;
1.47 x 10⁴g = 14.7kg
convert the height to m;
1000mm = 1m
6.34 x 10⁴mm gives 63.4m
Work done = 14.7 x 9.8 x 63.4 = 9133.4J
Time taken = = 4.2s
Because of ionization energy it takes more energy to gain electrons for this conductor than to lose and therefore it’s harder or it could be that after the first electron it’s orbit was filled and adding more electrons was forcing it to create a new shell
<span>Answer: capillary oncotic pressure.
In the vascular system, there is the hydrostatic pressure that caused by the heart pumping the blood and oncotic pressure that caused mostly by protein. This pressure keeps the water inside the blood vessel and a change can cause some disease.
Low protein in the blood can cause edema which was the water inside blood vessel come out to interstitial tissue because the oncotic pressure is dropped.</span>
