For the following types of electromagnetic radiation, how do the wavelength, frequency, and photon energy change as one goes fro

KIM [24]

Answer:

Wavelength, frequency and the photon energy changes as the one goes across the ranges of the electro-magnetic radiations.

Explanation:

Electro-magnetic radiations may be defined as the form of energy that is radiated or given by the electro-magnetic radiations. The visible light that we can see is the one of the electro-magnetic radiations. Other forms are the radio waves, gamma waves, UV rays, infrared radiations, etc.

The wavelength of the radiations decreases as we go from a. radio waves -- b. infrared radiation -- c. visible light -- d. ultraviolet radiation -- e. gamma radiation.

The frequency of the radiations increases when we move from a. radio waves -- b. infrared radiation -- c. visible light -- d. ultraviolet radiation -- e. gamma radiation.

The photon energy of the radiations increases when we move from a. radio waves -- b. infrared radiation -- c. visible light -- d. ultraviolet radiation -- e. gamma radiation.

Let the rescue boat starts at an angle theta with the North

now its velocity towards East is given as

$v_x = 24sin\theta$

$v_y = -24cos\theta + 3$

now in some time "t" it will catch the boy

so we will have

$t = \frac{0.5}{24sin\theta}$

also we have

$t = \frac{2}{-24cos\theta + 3}$

now we have

$\frac{2}{-24cos\theta + 3} = \frac{0.5}{24sin\theta}$

$4*24sin\theta = - 24cos\theta + 3$

$96 sin\theta + 24cos\theta = 3$

by solving above we got

$\theta = 164 degree$

__________ skids occur when you suddenly press too hard on the accelerator and the drive wheels lose traction.

Fynjy0 [20]

Answer:

Power Skids

Explanation:

Power Skid like the question suggested, is a skid that occurs when you suddenly press too hard on the accelerator and the drive wheels lose traction. Power Skid is one of the 4 types of Skids. The other 3 includes;

Cornering skid

Blowout skid and

Braking skid.

Power skid occurs mostly as a result of insanely high speed and or acceleration,when the accelerator is pressed on too suddenly causing the vehicle to be driven beyond its capabilities, and then to skid, ultimately.

What advantage does a modern camera offer a pinhole camera

AleksAgata [21]

Answer:

Done

Explanation:

The differences are significant. The main disadvantages of a pinhole camera compared to a modern camera are:

Proper exposure requires a trial and error approach.

Requires manual control of shutter speed (difficult to control)

Poor image quality (due to diffraction effects).

Long exposures (lead to blurry images if the subject moves).

Fixed aperture or f-stop.

Advantages include:

Large depth of field.

Inexpensive

Robust and nearly 100% reliable.

If used properly can create artistic effects.
