Answer:
857.5 m
2.8583×10⁻⁶ seconds
Explanation:
Time taken by the sound of the thunder to reach the student = 2.5 s
Speed of sound in air is 343 m/s
Speed of light is 3×10⁸ m/s
Distance travelled by the sound = Time taken by the sound × Speed of sound in air
⇒Distance travelled by the sound = 2.5×343 = 857.5 m
⇒Distance travelled by the sound = 857.5 m
Time taken by light = Distance the light travelled / Speed of light
Time taken by light = 2.8583×10⁻⁶ seconds
Answer:
a
The x- and y-components of the total force exerted is
b
The magnitude of the force is
The direction of the force is
Clockwise from x-axis
Explanation:
From the question we are told that
The magnitude of the first charge is
The magnitude of the second charge is
The position of the second charge from the first one is
The magnitude of the third charge is
The position of the third charge from the first one is
The position of the third charge from the second one is
The force acting on the third charge due to the first and second charge is mathematically represented as
Substituting values
The magnitude of is mathematically evaluated as
The direction is obtained as
