Answer:

Explanation:

Acceleration = a change in velocity / a change in time

Acceleration = ( final velocity - initial velocity) / a change in time

Acceleration = (6m/s - 35 m/s ) / 5 s

= (-29 m/s) /( 5 s)

= - 5.8 m/s^^2

Remember Significant Figures

- 6 m/s^2

P.S I have no idea why the answers say m/s because acceleration is m/s^2.

Imagine a particle that has three times the mass of the electron. All other quantities given above remain the same. What is the

melamori03 [73]

Answer:

The only parameter that changes is mass m

It is only necessary to calculate the ratio Eh/Ee

$m_{h}=3m_{e}\\E_{h}=\frac{3m_{e}v^{2}}{2}\\E_{e}=\frac{m_{e}v^{2}}{2}\\\frac{E{h}}{E{e}}=3$

The kinetic energy of the heavy paricle is three times the kinetic energy of an electron

A laser dazzles the audience in a rock concert by emitting green light with a wavelength of 533 nm . Calculate the frequency of

atroni [7]

Answer:

f = 5.63 x 10¹⁴ Hz

Explanation:

Given,

speed of light, c = 3 x 10⁸ m/s

wavelength,λ = 533 n m = 5.33 x 10⁻⁷ m

frequency, f = ?

using formula of frequency

$f = \dfrac{c}{\lambda}$

c is the speed of light

$f = \dfrac{3\times 10^{8}}{5.33\times 10^{-7}}$

f = 5.63 x 10¹⁴ Hz

hence, the frequency of the light is equal to f = 5.63 x 10¹⁴ Hz

olchik [2.2K]

Answer:

C)T

Explanation:

The period of a mass-spring system is:

$T=2\pi\sqrt\frac{m}{k}$

As can be seen, the period of this simple harmonic motion, does not depend at all on the gravitational acceleration (g), neither the mass nor the spring constant depends on this value.
