Wavelength = (speed) / (frequency)
Wavelength = (320 m/s) / (300 / sec)
Wavelength = (1 and 1/15) m/s
Answer:
Work done is equal to 125.44 J
Explanation:
We have given mass of the student m = 80 kg
Distance moved d = 4 m
Acceleration due to gravity
Coefficient of kinetic friction
So normal force exerted by student
We know that work done is equal to multiplication of force and distance
So work done
The coordinate of zero electric field of the two charges is (9.4 cm, 34.6 cm).
<h3>Coordinate points of zero electric field</h3>
The electric field strength of a charge is defined as force per unit charge.
At zero net electric field, the electric field of the two charges will be equal.
Let the point of zero electric field = x
Thus, the coordinate of zero electric field of the two charges is (9.4 cm, 34.6 cm).

Hello there! Your answer is (255/25=9) hope it helps and have a wonderful day!
The speed of an object can be determined from the distance vs time graph.
You know that speed = distance/time
in the graph, distance/time = slope of the curve.
So SPEED IS GIVEN BY THE SLOPE of the curve in the graph.
● If the distance vs time curve is a straight line, parallel to time axis(x-axis), slope is 0. That means speed is 0. So the object is at rest.
● If the distance vs time curve is a straight line, with some non-zero slope; That means speed is nonzero and constant. So the object is in uniform motion.
● If the distance vs time curve is a curved, the slope is changing. That means speed is changing. So the object is in an accelerated motion.
