Answer:
a) 0.21N/C
b) counterclockwise
Explanation:
a) to find the magnitude of the electric field you can use the following formula:
A: area of the ring = pi*r^2
E: electric field
Ф_B: magnetic flux
In the line integral you can assume E as constant. Furthermore, you calculate the change in the magnetic flux by taking into account that the time interval is 1.12/0.21=5.33s. By replacing in the formula you obtain:
the magnitude if the induced electric field is 0.21N/C
b) By the Lenz's law you can conclude that the current has a direction in a counterclockwise
The distance to the Earth at the moment of the landing craft's launch as measured by the aliens is 0.16 light years.
To find the answer, we have to know about the Lorentz transformation.
<h3>
What is the distance to the Earth at the moment of the landing craft's launch as measured by the aliens?</h3>
It is given that, an alien spaceship traveling at 0.600 c toward the Earth, in the same direction the landing craft travels with a speed of 0.800 c relative to the mother ship. We have to find the distance to the Earth at the moment of the landing craft's launch as measured by the aliens.
- It is given that; the spaceship is 0.200 ly from the Earth when the landing craft is launched.
- By Lorentz transformation equation, the value of the distance to the Earth at the moment of the landing craft's launch as measured by the aliens will be,
Thus, we can conclude that, the distance to the Earth at the moment of the landing craft's launch as measured by the aliens is 0.16 light years.

Answer:
In a unit government, all the powers of government are moved around in the central government where in turn in a federal government, the powers of government are divided between the center and the units.

Answer:
494.45 m.
Explanation:
Echo: This is the sound heard after the reflection of sound wave in a plain surface.
v = 2x/t................................ Equation 1
Where v = velocity of sound in air, x = distance between the mountain and the hikers, t = time to hear the echo.
making x the subject of the equation,
x = vt/2........................... Equation 2
Given: v = 341 m/s, t = 2.9 s.
Substitute into equation 2
x = 341(2.9)/2
x = 494.45 m.
Hence the mountain is 494.45 m far away
Here's a picture of Kinematic formulas
The kinematic formulas are a set of formulas that relate the five kinematic variables listed below.
Δx - Displacement
t - Time interval
v0 - Initial velocity
v- Final velocity
a - Constant acceleration
