Which sequence shows electromagnetic waves arranged from shorter to longer wavelengths?. A. visible light, infrared radiation, m

joja [24]

Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.

Explanation:

Shorter wavelength means higher frequency and higher energy.

Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:

D.ultraviolet rays, visible light, infrared radiation, microwaves.

Ultraviolet rays have shorter wavelength (about 380 nm) and high energy.

Visible light has wavelength: 380 nm to 700 nm

Infrared wavelength: 700 nm to 1 mm

Microwave wavelength: 1 mm to 1 m

A 0.40 kg object is attached to a spring with force constant 157 N/m so that the object is allowed to move on a horizontal frict

nirvana33 [79]

Answer:

Part a)

$F = 26.7 N$

Part b)

$a = 66.7 m/s^2$

Explanation:

Part a)

Force on the object due to spring force is given as

$F = kx$

here we know that

$k = 157 N/m$

$x = 0.17 m$

so we have

$F = 157\times 0.17$

$F = 26.7 N$

Part b)

Acceleration of the object is given as

$a = \frac{F}{m}$

$a = \frac{26.7}{0.40}$

$a = 66.7 m/s^2$

What direction does centripetal acceleration point?

Nesterboy [21]

Answer:

Inward

Explanation:

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced. hope this helps :)

A rescue pilot drops a survival kit while her plane is flying at an altitude of 2000.0 m with a forward velocity of 100.0 m/s. I

Nastasia [14]

Answer:

H = 1/2 g t^2 no original vertical velocity

t = (2 * 2000 / 9.8)^1/2 = 20.2 s

Sx = 100 m/s * 20.2 s = 2020 m
