A charged particle enters a uniform magnetic field B with a velocity v at right angles to the field. It moves in a circle with p
alukav5142 [94]

A) d. 10T

When a charged particle moves at right angle to a uniform magnetic field, it experiences a force whose magnitude os given by

F=qvB

where q is the charge of the particle, v is the velocity, B is the strength of the magnetic field.

This force acts as a centripetal force, keeping the particle in a circular motion - so we can write

qvB = \frac{mv^2}{r}

which can be rewritten as

v=\frac{qB}{mr}

The velocity can be rewritten as the ratio between the lenght of the circumference and the period of revolution (T):

\frac{2\pi r}{T}=\frac{qB}{mr}

So, we get:

T=\frac{2\pi m r^2}{qB}

We see that this the period of revolution is directly proportional to the mass of the particle: therefore, if the second particle is 10 times as massive, then its period will be 10 times longer.

B) a. f/10

The frequency of revolution of a particle in uniform circular motion is

f=\frac{1}{T}

where

f is the frequency

T is the period

We see that the frequency is inversely proportional to the period. Therefore, if the period of the more massive particle is 10 times that of the smaller particle:

T' = 10 T

Then its frequency of revolution will be:

f'=\frac{1}{T'}=\frac{1}{(10T)}=\frac{f}{10}

In which direction is the magnetic force acting on the charge? into the screen out of the screen up down
Harrizon [31]

The direction in which the magnetic force is acting on the charge is upwards.

<h3>What is Magnetic force?</h3>

This is the attraction and repulsion which usually occurs during the motion of electrically charged particles.

In the magnetic field, the charge is moving to the left. Therefore the direction the magnetic force is acting on the charge is upwards which is gotten via right hand rule.

Use the mass and volume data to calculate the density of liquid propane to the nearest hundredth.
Black_prince [1.1K]
Density = mass/volume 
              = 4300/10000
              =    0.43 g/mL.

Therefore density of liquid propane is 0.43 g/mL.

Hope this helps!

A scientist spends most of her time observing the motion of objects and how they behave. Which branch of science is she most lik
olga55 [171]
The scientist is likely to be studying kinematics.
Kinematics is the branch of science, specifically physics, which is concerned with the motion of objects without reference to the forces that induce this motion. An example of kinematics is studying the change in velocity of an object over time or the distance covered by an object in a specified amount of time.

Physics laws of motion
expeople1 [14]

The acceleration is 0.095 m/s^2

Explanation:

We can solve the problem by applying Newton's second law of motion: in fact, the net force acting on an object is equal to the product between the mass of the object and its acceleration. Therefore we can write:

\sum F = ma

where:

\sum F is the resultant force acting on the object

m is its mass

a is its acceleration

In this problem, we have the following forces acting on the system:

F_1 = 2500 N (forward)

F_2 = -2400 N (backward)

So, Newton's second law can be rewritten as:

F_1 -F_2 = ma

where:

m = 1050 kg is the mass of all the students

Solving the formula for a, we find the acceleration of the system:

a=\frac{F_1-F_2}{m}=\frac{2500+(-2400)}{1050}=0.095 m/s^2
