What is one way that an electric field is different from a magnetic field?

wel

Answer:

The one of the major difference between the magnetic and electric field is that the electric field induces around the static charge particle which is either negative or positive, whereas the magnetic field produces around the poles (i.e., the north and south pole) of the magnet

A diffraction grating produces a first-order bright fringe that is 0.18 m away from the central bright fringe on a flat screen.

Georgia [21]

Answer:

The wavelength of the light is 562.5 nm

Solution:

As per the question:

Order, n = 1

Slit separation, d = $2.5\times 10^{- 6}\ m$

Distance from the bright fringe, y = 0.18 m

Distance between the screen and the grating, D = 0.8 m

Now,

We know from the eqn for diffraction:

$n\lambda = dsin\theta$

n = 1

$\lambda = dsin\theta$ (1)

Also,

For very small angle, $\theta$ :

$sin\theta$ ≈ $tan\theta = \frac{y}{D} = \frac{0.18}{0.8} = 0.225$

Using the above value in eqn (1):

$\lambda = 2.5\times 10^{- 6}\times 0.225 = 5.625\times 10^{- 7}\ m = 562.5\ nm$

What three assumptions about particles in a gas are made by the kinetic theory?

aliya0001 [1]

The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the walls of the container, but otherwise do not interact; and (3) the transfer of kinetic energy between molecules is heat.

a centrifugal force ride, similar to the gravitron, spin at a speed of 22 revolutions per minute. if the diameter of the ride is

Margarita [4]

The linear speed of the passengers in kilometres/hour is 1.152 km/h.

The centrifugal force ride spins at a speed of 22 rev/min. The diameter of the ride is 14 meters.

We know,

Diameter = 2(Radius)

Radius = 14/2m

Radius = 7m

Radius of the centrifugal ride is 7m.

Also,

1 rev = 2π radians

22 rev = 44π radian

Angular Speed in rad/s = 44π/60

The relationship between the angular speed W and the linear speed V is given as,

V = W/R

R is the radius of the circle,

Now, putting the values,

V = 44π/(60×7)

V = 0.32 m/s.

So, the linear speed of the passengers is 0.32 m/s.

It is know, for conversion from m/s to km/h

1 m/s = 3600/1000 km/h

So, 0.32m/s in km/h is,

0.32m/s = 0.32 × 3600/1000

Linear speed in km/h is 1.152km/h.
