The direction of deflection of an electron beam in a magnetic field can be determined by which of the following?
amid [387]

Answer:

Right Hand Rule

Explanation:

When a charged particle travels in a magnetic field, it experiences a force whose magnitude is given by:

F=qvBsin\theta

where

q is the charge of the particle

v is the velocity

B is the magnetic field strength

\theta is the angle between the directions of v and B

The direction of the force can be determined by using the Right Hand Rule, as follows:

- index finger: this should be put in the direction of the velocity

- middle finger: this should be put in the direction of the magnetic field

- thumb: this will give the direction of the force -> however, for a negative charge (as the electron) the direction must be reversed, so it will be opposite.

A 23.9 g sample of iridium is heated to 89.7 oC, and then dropped into 20.0 g of water in a coffee-cup calorimeter. The temperat
Nikolay [14]

Answer:

The specific heat capacity of iridium = 0.130 J/g°C

Explanation:

Assuming no heat losses to the environment and to the calorimeter,

Heat lost by the iridium sample = Heat gained by water

Heat lost by the iridium sample = mC ΔT

m = mass of iridium = 23.9 g

C = specific heat capacity of the iridium = ?

ΔT = change in temperature of the iridium = 89.7 - 22.6 = 67.1°C

Heat lost by the iridium sample = (23.9)(C)(67.1) = (1603.69 C) J

Heat gained by water = mC ΔT

m = mass of water = 20.0 g

C = 4.18 J/g°C

ΔT = 22.6 - 20.1 = 2.5°C

Heat gained by water = 20 × 4.18 × 2.5 = 209 J

Heat lost by the iridium sample = Heat gained by water

1603.69C = 209

C = (209/1603.69) = 0.130 J/g°C

A car accelerates from rest for 5 seconds until it reaches a speed of 20 m/s. what is the car's acceleration in meters per secon
barxatty [35]
Acceleration = change in velocity divided by time taken...

I.e Acceleration = (Final velocity - Initial Velocity) /time taken...

The question says the body accelerate from rest... Therefore it's initial velocity = 0

It reach a speed(velocity) of 20m/s.. My final velocity

And the time taken to attain the velocity = 5 seconds....

Therefore

acceleration = (20-0)/5

a = 20/5

a = 4ms¯²

Hope this helped....
