Answer:
The magnitude of the EMF is 0.00055 volts
Explanation:
The induced EMF is proportional to the change in magnetic flux based on Faraday's law:
Since in our case there is only one loop of wire, then N=1 and we get:
We need to express the magnetic flux given the geometry of the problem;
where A is the area of the coil that remains unchanged with time, and B is the magnetic field that does change with time. Therefore the equation for the EMF becomes:
Answer:
269,000
Explanation:
The distance between Proxima Centauri and the Sun, d₁₁ = 4.246 light years
The distance between Earth and the Sun, d₂ = 1.58 × 10⁻⁵ light years
The ratio of the distances are;
d₁/d₂ = 4.246/(1.58 × 10⁻⁵) = 268734.177215 ≈ 269,000 times
Therefore, Proxima Centauri is approximately 269,000 times further from the Sun than the Earth is from the Sun
Answer:
Explanation:
velocity of ship with respect to water = 6.5 m/s due north
velocity of water with respect to earth = 1.5 m/s at 40° north of east
velocity of ship with respect to water = velocity of ship with respect to earth - velocity of water with respect to earth
The magnitude of the velocity of ship relative to earth is = 5.66 m/s
Answer:
The value is
Explanation:
From the question we are told that
The uniform acceleration is
The time considered is
Generally the from kinematic equation we have that
Given that the boat started from rest , the initial velocity is u = 0 m/s
So
=>
