Answer:
Total time spend = 48.18 hours (Approx)
Explanation:
Given:
Total distance = 5,300 km
Average speed = 110 km / h
Find:
Total time spend
Computation:
Time = Distance / speed
Total time spend = Total distance / Average speed
Total time spend = 5,300 / 110
Total time spend = 48.18 hours (Approx)
Panel surface area =34m×46m=1,564m^2
total power =1564m^2×1390w/m^2
=2173960watts
now you must calculate total energy.
Energy = power×Time
However time must be in seconds so we multiply 2hrs×60min×60s=7200seconds
7200s×2173960w =15,652,512,000 joules of energy
Answer:
4/5 houses
Explanation:
The speed of the first carpenter is:
(1/5 house) / (3/4 day) = 4/15 house/day
The speed of the second carpenter is:
(2/5 house) / (3/4 day) = 8/15 house/day
Together, their combined speed is:
4/15 house/day + 8/15 house/day = 12/15 house/day
= 4/5 house/day
Per day, the two carpenters build 4/5 of a house.
you would have C) two north poles and two south poles
Answer:
Explanation:
Given charges are:
The electric potential energy of a charge due to the electric field of another charge is given by
where,
- k = Coulomb's constant, having value =
- r = distance between the charges.
When the charges are infinite distance apart, 
,
When the charges are 
apart, 
,
Here, e is the charge on one electron, such that, 
.
Therefore,
Thus,
