Answer:
the magnitude of the magnetic field is 1.23 x 10⁸ T.
Explanation:
Given;
magnitude of the electric field, E = 3.7 V/m
The magnitude of the magnetic field is calculated as;
E = cB
where;
B is the magnitude of the magnetic field
c is the speed of light = 3 x 10⁸ m/s
From the above equation, the magnetic field, B, is calculated as;
Therefore, the magnitude of the magnetic field is 1.23 x 10⁸ T.
let the plane is flying at some angle theta with west towards north
Now we can use the components
now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say
so plane has to fly in direction 14.5 degree North of west
Power = work / time --> time = work / power = 3600 J / 275 watts = 13.1 seconds.

Answer:
The original dimensions of the building is 95 ft × 38 ft.
Explanation:
Let the original length be 'l' and original width be 'w'.
Given:
Original length (l) =
Original width = 'w'.
So,
Now, as per question:
Length and width is increased by 7 ft.
So, new length (l') =
New width (w') =
New perimeter (P) = 266 ft
Perimeter is given as:
Therefore, original width = 38 ft.
Original length is,
Hence, the original dimensions of the building is 95 ft × 38 ft.
