Forces start and change the motion of an object. Question 1 options: True False

The power ratings of several motors are listed in the table. A 2 column table with 3 rows. The first column is labeled motor wit

Lapatulllka [165]

The statement " Brand-W motor does 7,640 N of your toughest work." can be truthfully use.

Advertisement Rules:

An advertiser can not compare its products using the other companies name.

An advertiser can not make the false statement in its advertisement.

Here, the brand-W has the power rating of 7,640 W that is less than brand-Y. Advertiser cannot compare his brand using the name of Brand X, Y, or Z.

Therefore, the statement " Brand-W motor does 7,640 N of your toughest work." can be truthfully use.

A charged particle enters into a uniform magnetic field such that its velocity vector is perpendicular to the magnetic field vec

Anit [1.1K]

Answer:

The charged particle will follow a circular path.

Explanation:

The magnetic force exerted on the charged particle due to the magnetic field is given by:

$F=qvB sin \theta$

where

q is the charge

v is the velocity of the particle

B is the magnetic field

$\theta$ is the angle between v and B

In this problem, the velocity is perpendicular to the magnetic field, so $\theta = 90^{\circ}, sin \theta=1$ and the force is simply

$F=qvB$

Moreover, the force is perpendicular to both B and v, according to the right-hand rule. Therefore, we have:

- a force that is always perpendicular to the velocity, v

- a force which is constant in magnitude (because the magnitude of v or B does not change)

--> this means that the force acts as a centripetal force, so it will keep the charged particle in a uniform circular motion. So, the correct answer is

The charged particle will follow a circular path.

A conducting sphere is charged up such that the potential on its surface is 100 V (relative to infinity). If the sphere's radius

Klio2033 [76]

Answer: the potental with twice larger radius 0.5* Vo ( being Vo =100V)

Explanation: In order to solve this proble, we know that teh potential due to charged sphere relative V=0 at infinity, we have

Vo=k*Q/R where R is the sphere radius

if we enlarge the radius to 2R the

V= k*Q/2*R = Vo/2

The data below show the distance that a circus net stretches when different masses are placed on it.

Nataly_w [17]

Answer:

48 kg

Explanation:

If you observe very closely, 55 would end up being closer to 60 than towards the middle. 48 lines up with the "disturbance of the force" more so than 55.
