The second option
You can see it in the name that see represents carbon and H represents hydrogen on the periodic table. The numbers after it are the amount of items that are in the molecule

What is the electric flux φ through each of the six faces of the cube? Use ϵ0 for the permittivity of free space?

exis [7]

If total charge Q is enclosed in the surface of cube

then we will have say that total flux linked with all surfaces of the cube will be given by

$\phi = \frac{Q}{\epsilon_0}$

since the position of charge is symmetric with respect to the center of the cube so here this whole flux will be equally linked with each of the face of the cube

So here total 6 faces of the cube is there and the total flux of the charge will equally divide in these 6 faces

so flux linked with each face is given by formula

$\phi = \frac{Q}{6\epsilon_0}$

so each face will have above flux due to central position of charge Q

A wire is stretched 30% what is the percent age change in resistance?

IgorC [24]

The Resistance is directly proportional to conductor length. Therefore 30% increase in wire length will increase the resistance by 30%.

Two spheres of the same mass are positioned on a 100 meter ramp with at 20 degree incline. Both spheres have a radius or 5 m and

xenn [34]

Answer:

Explanation:

acceleration of a rolling body down an inclined surface is given by the formula

a = g sinθ / 1 + k² / R² , θ is inclination , k is radius of gyration , R is radius

It will not depend upon mass .

for solid sphere

k , radius of gyration = √(2/5)R

k² / R² = 2/5 = .4

a = g sin20 / (1 + .4 )

= 2.4 m /s²

from s = ut + 1/2 at²

100 = .5 x 2.4 t²

t = 9.13 s

For hollow sphere

k , radius of gyration = √(2/3)R

k² / R² = 2/3 = .67

a = g sin20 / (1 + .67 )

= 2 m /s².

from s = ut + 1/2 at²

100 = .5 x 2 t²

t = 10 s

So time taken are 9.13 and 10 s respectively.
