Answer:

D. A low lambda, λ, and a high nu, ν

Explanation:

Both x-rays and radio waves are electromagnetic waves that are part of the electromagnetic spectrum.
Radio waves have the longest wavelengths in the electromagnetic spectrum and the lowest frequency.
X-rays on the other hand have a higher frequency compared to radio waves and a lower wavelength than that of the radio waves.
All electromagnetic waves in the electromagnetic waves travel with a speed of light, 3.0 × 10^8 m/s. They also posses energy given by the formula E = hf, where h is the plank's constant.

A 465 g block slides along a frictionless surface at a speed of 0.35 m/s. It runs into a horizontal massless spring with spring

katovenus [111]

Answer:

a) The duration, during which the block remain in contact with the spring is 0.29 s

b) The period of the simple harmonic oscillatory motion depends only on the mass and spring constant, therefore when the speed is doubled, the duration of contact remains the same as 0.29 s.

Explanation:

Mass of the block = 465 g

Surface speed = 0.35 m/s

Spring constant , k = 54 N/m

$T = 2\times \pi \times \sqrt{\frac{m}{K} } = 2\times \pi \times \sqrt{\frac{0.465}{54} }$ = 0.58 s
