Explanation:
the unit of area is called a derived unit because it is made of two fundamental unit metre and metre.
Answer:
fossil fuels are being used more because fossil fuels are of great importance because they can burn to produce a significant amount of energy per unit mass the use of coal as a fuel prefates recorded history.
Explanation:
Hope this helps! :)
Therefore the world's record high temperature of 134.0°F (56.7°C) is held by Furnace Creek Ranch in Death Valley, California. That global high temperature was attained on July 10, 1913.
In triangle ABC , using Pythagorean theorem
BC = sqrt(AB² + AC²)
r = sqrt(y² + x²) eq-1
taking derivative both side relative to "t"
dr/dt = (1/(2 sqrt(y² + x²) ) ) (2 y (dy/dt) + 2 x (dx/dt))
dr/dt = (1/(2 sqrt(0.5² + 0.5²) ) ) (2 (0.5) (dy/dt) + 2 (0.5) (dx/dt))
dr/dt = (1/(2 sqrt(0.5² + 0.5²) ) ) ( v₁ + v₂)
15= (1/(2 sqrt(0.5² + 0.5²) ) ) ( - 30 + v₂)
v₂ = 51.2 m/s
at 2.304×10⁹m the electric field magnitude equal to 2.50 nc.
electric field due to a long uniformly charged wire is given as,
E= 2kλ/r
where,
k is a constant
λ is uniform charge density
r is the distance from the wire
λ = 3.20 × 10⁻¹⁰C/m
k= 9×10⁹
therefore r = 2kλ/E
on substituting value we get,
r= 2.304×10⁹m
