The Hubble telescope’s orbit is 5.6 × 105 meters above Earth’s surface. The telescope has a mass of 1.1 × 104 kilograms. Earth exerts a gravitational force of 9.1 × 104 newtons on the telescope. The magnitude of Earth’s gravitational field strength at this location is

Answers

Gravitational force = 9.1 x 10⁴ newtons

Mass = 1.1 x 10⁴ kilograms

Gravitational field strength = 9.1 x 10⁴ newtons / 1.1 x 10⁴ kilograms

= ( 9.1 / 1.1) (newton / kilogram)

= 8.3 newton/kg

or 8.3 m/s² .

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:

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

What is a scientific paradigm

Answers

a scientific paradigm is is a distinct set of concepts or thought patterns, including theories, research methods, postulates, and standards for what constitutes legitimate contributions to a field.

Audition begins when sound waves strike the ________,causing it to vibrate. A) eardrum B) anvil C) stirrup D) cochlea

Answers

Answer: A) eardrum

Explanation: Audition refers to the sense of hearing. It is the process by which sound waves are perceived and interpreted by our brain. When sound waves enter the ear, they cause the eardrum to vibrate. These vibrations then travel further into the inner ear, leading to a chain of events that ultimately allows us to interpret and understand the sounds that we hear. Therefore, A is correct.

What is HOV lanes?

High-Occupancy Vehicle (HOV) lane is a lane that is designated for use by certain types of vehicles with a specified number of occupants.

It can offer travel-time savings to those who choose to carpool or take transit.

HOV lanes can move a greater number of people than a general traffic lane, and encourage carpooling and transit use by providing travel-time savings and a more reliable trip time.

HOV lanes are open 24 hours a day, seven days a week.
