Answer:
This is very hard bit I think 6.3 my, I'm not shure.
Answer:
y = 0.1 m
Explanation:
The electrical power for point loads is
V = 
k Sum qi / ri
in this case
V = k (
)
indicate that V = 0
r₂ = 
the distance r1 is
r₁ = y -0
the distance r2
r₂ = 0.14 -y
we substitute
0.14 - y = 
y
y ( 
) = 0.14
y 1.4 = 0.14
y = 0.14 / 1.4
y = 0.1 m
Work is performed while initially lifting books off the floor. The work is due to gravity.
KE = 1/2 * m * v2
We have to rearrange this so the subject is mass. (because the question asks for the mass of the object) :
Mass = (2 * KE) / v
Now input the values into this equation to get your answer :
Mass = (2 * KE) / v
Mass = (2 * 480) / 8
Mass = 960 / 8
Mass = 120
Answer:
volume = 339008 cubic feets
weight = 25397.253 pounds
Explanation:
a) 1 feet = 3.2808 m
volume = length×breath×height
(40*3.2808)*(20*3.2808)*(12*3.2808
=339008 cubic feets
b) weight = volume * density
= (40*20*12)*1.20
= 11520 kg
= 25397.253 pounds
