Answer:
4.38 %
Explanation:
Given that,
The experimental value of gravity is 10.24 m/s²
The general accepted value of gravity is 9.81 m/s²
We need to find the percent error of the experimental versus accepted values of gravity.
The formula used to find the percentage error is given by :
Putting all the values:
So, the percentage error is 4.38 %.
Answer:
emf = 15 * Area and if A is given in square meters, the units of the emf will be Volts
Explanation:
Assuming that the area of the loop of current (A) is known, the magnitude of the induced emf can be calculated using Faraday-Lenz's Law:
and if the area (A) is given in square meters, the emf will directly come in units of Volts.
Answer:
True
Explanation:
The normal line is defined as the line which is perpendicular to the reflecting surface at the point where the incident ray meet with the reflecting surface.
The angle of incident is defined as the angle which is subtended by the incident ray with respect to the normal ray by consider the normal ray as the base line and angle is measured from the point where incident ray is incident on the reflecting surface of the mirror.
Similarly reflecting ray can be defined as the ray which is reflected after the incident of a ray and the angle subtended by the reflecting ray is measure with respect to normal ray by considering normal ray as a base line.
Therefore, the normal ray is the perpendicular line to the reflecting surface at the point of incidence.
