Answer:

56.9 fN

Explanation:

The force exerted on the electron is:

F=Bqv

where

B is the magnetic field strength

q is the electron's charged

v is the speed of the electron

In our problem,

B = 0.049 T

q=1.6\cdot 10^{-19} C

v=7.26\cdot 10^6 m/s

Therefore, the force is

F=(0.049 T)(1.6\cdot 10^{-19} C)(7.26\cdot 10^6 m/s)=5.69\cdot 10^{-14} N=56.9 fN

Jill is pushing a box across the floor. Which represents the upward force perpendicular to the floor?
Georgia [21]

Answer:

When Jill is pushing a box across a floor, it represents the upward motion and it is natural force is applied.

So it is represented as FN and normal force takes place in considering the force perpendicular to the floor.

It seems to support that forced applied on an object when the object is in contact with other.

What did the asymptote say to the removable discontinuity worksheet answers?
ra1l [238]

“Don't hand that holier than thou line to me” is what the asymptote said to the removable discontinuity.

 

 

The distance between the curve and the line where it approaches zero as they tend to infinity is the line in the asymptote of a curve. This is unusual for modern authors but in some sources the requirement that the curve may not cross the line infinitely often is included.

 

The point that does not fit the rest of the graph or is undefined is called a removable discontinuity. By filling in a single point, the removable discontinuity can be made connected.

The charge on any negatively charged oil droplet is always a whole-number multiple of the fundamental charge of a single electro
shusha [124]

Answer:

1.6\times 10^{-18} C  

Explanation:

The fundamental charge of a single electron is 1.6\times 10^{-19} C.

If there are 10 excess electrons, the net charge that would be measured should be 10 times the fundamental charge of a single electron:

Q=nq_e\\Q= 10\times 1.6\times 10^{-19} C\\Q= 1.6 \times 10^{-18} C
