Answer:
Explanation:
It is given that,
Radius of the circular loop, r = 0.7 m
Magnetic field, B = 0.44 T
In 0.14 s the wire is reshaped from a circle into a square, but remains in the same plane.
Area of the circular wire,
For the area of square,
The circumference of wire,
Side of square,
Area of square,
An emf is induced in the loop due to change in its area. The induced emf is given by :
So, the magnitude of the average induced emf is 1.10 volts. Hence, this is the required solution.
Answer:To find an object's mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons.
Explanation:In the formula for determining mass based on weight, mass is measured in Newtons.
The relationship between wavelength, frequency and speed of an electromagnetic wave is
where
is the wavelength of the wave
c is the speed of light
f is the wave's frequency
The wave in this problem has frequency
, so its wavelength is
The answer is 6.04 × 10^4 N/C.
Formula for the strength of the electric field is:
E = F/q
E = 2.72 × 10^-3 N/4.50 × 10^-8 C
E = 0.60444 × 10^5 N/C
E = 6.04 × 10^4 N/C
Answer:
You can compare and contrast the scientific method to the engineering design process
