An electron travels with speed 6.0 106m/s between the two parallel charged plates shown in the figure. The plates are separated by 1.0 cm and are charged by a200 V battery.What magnetic field strength will allow the electron to pass between the plates without being deflected?

Answers

The magnetic field strength will allow the electron to pass between the plates without being deflected is 0.0033 T.

Electric field strength

The electric field strength of the electron is calculated as follows;

E = V/d

E = 200/(0.01)

E = 20,000 V/m

Magnetic field strength

The magnetic field strength is related to electric field in the following formula;

qvB = qE

vB = E

B = E/v

B = (20,000)/(6 x 10⁶)

B = 0.0033 T

Thus, the magnetic field strength will allow the electron to pass between the plates without being deflected is 0.0033 T.

Answer:

3.3 mT

Explanation:

First of all, we need to find the strength of the electric field between the two parallel plates.

We have:

$\Delta V=200 V$ (potential difference between the two plates)

$d=1.0 cm=0.01 m$ (distance between the plates)

So, the electric field is given by

$E=(\Delta V)/(d)=(200 V)/(0.01 m)=2\cdot 10^4 V/m$

Now we want the electron to pass between the plates without being deflected; this means that the electric force and the magnetic force on the electron must be equal:

$F_E = F_B\nqE=qvB$

where

q is the electron charge

E is the electric field strength

v is the electron's speed

B is the magnetic field strength

In this case, we know the speed of the electron: $v=6.0\cdot 10^6 m/s$ , so we can solve the formula to find B, the magnetic field strength:

$B=(E)/(v)=(2\cdot 10^4 V/m)/(6.0\cdot 10^6 m/s)=0.0033 T=3.3 mT$

9. Which of the following is true regarding current in an external circuit? A. A direct current constantly switches direction of flow to match the change of charge at each terminal.
B. Direct current always moves from the positively charged terminal to the negatively charged terminal.
C. Alternating current always moves from the positively charged terminal to the negatively charged terminal.
D. The flow of an alternating current switches direction when a generator's terminals change its charge.

Answers

The statement that best describes an external circuit is "D. The flow of an alternating current switches direction when a generator's terminals change its charge." The main difference between direct and alternating current is the direction of flow. Direct current follows only one direction from negatve to positive, while alternating current changes direction periodically.

Answer: D. The flow of an alternating current switches direction when a generator's terminals change its charge.

Because of convection, the warmest air in a room A. spreads out in all directions.
B. rises toward the ceiling.
C. transfers heat to the walls.
D. sinks toward the floor.

Answers

The correct choice is
B. rises toward the ceiling
In fact, the warmest air is also the air with least density: in warm air, the particles move faster, so the distance between them is larger, on average. Therefore, the warmest air is less dense, and because of that it tends to flow upwards (due to Archimede's principle) and it is replaced by the colder air, creating the so-called convection current.

Using the value of atmospheric pressure at sea level, 1 × 105 Pa, estimate the total mass of the earth's atmosphere above a 5-m2 area.

Answers

Answer:

5×10^4 kg

Explanation:

pressure= force/Area

area= 5m^2

pressure = 1×10^5 Pa

1×10^5=mg/5 (weight will be the force)

5×10^5=m×10 (gravitational field strength of the earth)

5×10^5×10^-1 =m

mass=5×10^4 kg!

hope this helps!

Which statement best describes perigee?A. The closet point in the Moon's orbit to Earth
B. The farthest point in the Moon's orbit to Earth
C. The closest point in Earth's orbit of the Sun
D. The Sun's orbit that is closest to the Moon

Answers

Answer:

A. The closest point in the Moon's orbit to Earth

Explanation:

The perigee is defined as the closest point in the orbit of an object (such as a satellite) from the centre of the Earth. In this case, the Earth's satellite is the Moon, so the perigee is defined as the closest point in the Moon's orbit to Earth. so option A is the correct one.

Let's see instead the names of the other options:

B. The farthest point in the Moon's orbit to Earth --> this point is called apogee

C. The closest point in Earth's orbit of the Sun --> this point is called perihelion

D. The Sun's orbit that is closest to the Moon --> this point has no specific name

A. The closet point in the Moon's orbit to Earth

Hope I helped:P
