Answer:

7.92×10^6Joules

Explanation:

Power is defined as the rate of change in work done. Mathematically, Power = Workdone/Time

Given power = 1.1×10³watts

Time = 2.0hours = 2×60×60

= 7,200seconds

Workdone = power × time

Work done = 1.1×10³×7200

Workdone = 7,920,000Joules

= 7.92×10^6Joules

Two vectors A and B are at right angles to each other. The magnitude of A is 3.00. What should be the length of B, so that the m

AfilCa [17]

Answer: length of B =4.00

Explanation:

for the vectors A and B and the angle between them as x.

Magnitude of the sum of A and B is given as = √(A²+B²+2ABcosx

where

Magnitude of A = 3.00

Magnitude of the sum of A and B is 5.00

5.00=√(A²+B²+2ABcos90°

5.00= √3² +b² +0

5²= 3² +b²

25=9+b²

b²= 25-9

b² = 16

b= √16

b= 4

guajiro [1.7K]

A single electron has a charge of
$e=-1.6 \cdot 10^{19}C$
Therefore, if we have an excess of $N=6.0\cdot10^6$ electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
$Q=Ne=(6.0\cdot10^6)(-1.6 \cdot 10^{-19}C)=9.6 \cdot 10^{-13}C$
