<h2>The flux through each face is q/6ε₀ .</h2>
Explanation:
The charge q is placed at the center of the cube of side L
According to Gauss's law the flux through any closed surface is q/ε₀
here q is the charge enclosed .
In this case cube has the six faces . The flux through each face = q/6ε₀
In the second case The cube has the face with length L₁
The flux through each face = q/6ε₀
Thus flux through the cube does not depend upon the size of the cube .
Things he should do
1) Take several readings.
2) And find the average of the readings to get the accurate value.
Things should not do
1) Avoid human error.
2) Zero error
Answer:
C) Mass of the ball
Explanation:
Independent variable is the variable the researcher changes.
Since Martin is testing the mass of the ball, he'll be using different balls and that is the only thing he changes.
The distance traveled by the ball is the dependent variable since it depends on the mass of the ball.
The height and length of the ramp are the constant variables since that's the only ones that remain the same throughout this experiment.
Answer:
h = 51020.40 meters
Explanation:
Speed of the rifle, v = 1000 m/s
Let h is the height gained by the bullet. It can be calculated using the conservation of energy as :
h = 51020.40 meters
So, the bullet will get up to a height of 51020.40 meters. Hence, this is the required solution.
