Answer:
v=2.9578 m/s
Explanation:
t= 1407.6 hr
t = 3600 * 1407.6 = 5067360 s
w = 2π/T
=2π/5067360
w = 1.24 x 10^-6 rad/s
v = r*w
v = 2.9758 m/s
Answer:
(a) The self inductance, L = 21.95 mH
(b) The energy stored, E = 4.84 J
(c) the time, t = 0.154 s
Explanation:
(a) Self inductance is calculated as;
where;
N is the number of turns = 1000 loops
μ is the permeability of free space = 4π x 10⁻⁷ H/m
l is the length of the inductor, = 45 cm = 0.45 m
A is the area of the inductor (given diameter = 10 cm = 0.1 m)
(b) The energy stored in the inductor when 21 A current ;
(c) time it can be turned off if the induced emf cannot exceed 3.0 V;
Because Earth orbits around the sun, causing the position to seemingly change as the Earth moves. Orion can't be seen in summer because it appears when the sun is out. The reason it doesn't appear at night is because the earth is titled differently on it's axis then in, say winter.
I hope this helps you out.
Answer:
Heat from the sun then warms the cold water at the surface, and evaporation leaves the water saltier. The warm salty water is then carried northwards; it joins the Gulf Stream, a large powerful ocean current that is also driven by winds
Explanation: The explanation is the answer
Answer:
An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected.
