Answer:

A red apple appears red because when white light illuminates the red apple all of the colors in

the white light are absorbed except the red light which is reflected. Since blue light one of the primary colors (and does not contain red light), when it illuminates a red apple the apple would appear black since there is no red light to be reflected back.

Which of the following choices concerning the net magnetic flux through any enclosed surface is true according to Gauss' law for

11Alexandr11 [23.1K]

Answer:

e. The net magnetic flux in this case would be equal to zero.

Explanation:

As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop

here we know that net magnetic flux is the scalar product of magnetic field vector and area vector

so here we have

$\int B. dA$ = net magnetic flux

since we know that magnetic field always forms closed loop so if we find the integral over a closed loop

then in that case the value of the close integral must be zero

so correct answer would be

e. The net magnetic flux in this case would be equal to zero.

Explain how the basic units are combined to give the derived units of force, velocity and pressure and work

Lorico [155]

#Force

$\\ \sf\longmapsto Force=Mass\times Acceleration$

$\\ \sf\longmapsto Force=kg m/s^2$

$\\ \sf\longmapsto Force=Newton (N)$

#Velocity

$\\ \sf\longmapsto Velocity=\dfrac{Displacement}{time}$

$\\ \sf\longmapsto Velocity=m/s$

#Work

$\\ \sf\longmapsto Work=Force\times Displacement$

$\\ \sf\longmapsto Work=Nm$

$\\ \sf\longmapsto Work=Joules(J)$

Choose the appropriate description for an electron.

DedPeter [7]

Answer:negative charge, small relative mass, and found outside the nucleus

Explanation:

The electron is one of the subatomic particles. It is negatively charged and has a relatively small or somewhat negligible mass. It is found outside the nucleus on the orbits. The electron is bound to the nucleus by electrostatic forces of attraction in the Bohr's model of the atom.
