Answer:
I = 12*B (the information about B does not appear in the statement)
Explanation:
The motion of the segment of the circuit, in a constant magnetic field makes that opposite charges inside the segment separate of each other. This generate a induced potential difference at the ends of the segment that is given by the following formula:
(1)
v: speed of the segment = 2.0m/s
B: magnitude of the magnetic field
(2)
The induced current calculated by replacing the result of (2) in the following formula:
(3)
Then, you only have to replace the value of the magnitude of the magnetic field B in (3) to calculate the current.
Since distances in the universe are incredible big, astronomers use Astronomical units, which the distance between the sun and the earth, to simplify calculations.
The Astronomical unit AU is the Earth’s average distance from the Sun. 1 AU is equivalent to 149,598,000 km or <span>92,955,807.273026 miles.
We can conclude that Astronomical units is the unit of measure that will be used to calculate the distance </span>between Venus and Earth.
Answer:The frequency of the echo is slightly decreased
Explanation:
Given
speed of boat
cliff is away
when boat is still , suppose t is the time taken by the echo to reach observer on the boat
But as soon as boat starts moving the distance between cliff and boat decreasing and time for echo to reach observer also decreases
and we know
therefore frequency of the echo slightly decreased.
Answer:
The green car traveled a shorter distance, but the displacement of the cars was equal.
