Answer:
W = 100000 J = 100 KJ
Explanation:
Here we will use the most basic and general formula of work, which is as follows:
where,
W = Work Done = ?
F = Force Required = 200 N
d = Length of Track = 500 m
Therefore,
<u>W = 100000 J = 100 KJ</u>
Answer:110v
Explanation:
Current=100 amperes
Resistance=1.1 ohms
voltage=current x resistance
Voltage=100 x 1.1
Voltage=110v
Jovian planets are also known as gas giants and are the four outer planets Jupiter, Saturn, Uranus and Neptune. Uranus stands out from this group because of the tilt of its axis. Uranus is tilted on its side. Scientists speculate that this tilt may be as a result of a collision with a large body just after the planet was formed. Uranus is tilted 98 degrees compared to earth's 23 degrees.

Answer:
option (a)
Explanation:
Wire 1:
length = 2L
Area = 2 A
Wire 2: length = L
Area = A
As we know that the resistance of a wire is directly proportional to the length of the wire and inversely proportional to the area of crossection of the wire.
Let ρ be the resistivity of the cooper wire.
Resistance of wire 1
R1 = ρ x 2L / 2 A = ρ L / A
Resistance of wire 2:
R2 = ρ x L / A = ρ L / A
As R1 = R2
It means both the wires have same resistance.
