Which has more momentum: a 30 kg bicycle moving at 10 m/s or a 300 kg car at rest?

Physics

Hatshy [7]3 years ago
5 0
<h2>Answer:</h2>

Momentum = mass × velocity

<h3>Case I </h3>

Momentum of bicycle = 30 × 10 = 300 kgms¯¹

<h3>Case II </h3>

Momentum of car = 300 × 0 = 0 kgms¯¹

<h3>Therefore, 300 > 0 so momentum of bicycle is more. Hence, option A is correct. </h3>

Answer:

In two significant figure 360K

Explanation:

The temperature difference (ΔT) can be calculated as the boiling temperature minus the freezing temperature in Fahrenheit.

Hence,

ΔT = 212 - 32

ΔT = 180°F

To convert to °F to kelvin, we use the formula below

= (°F - 32) × 5/9 + 273.15

= (180°F - 32) × 5/9 + 273.15

= 355.37K ⇔ 360K

A wave is described by y=0.0200 sin (kx - ωt) , where , ω = 3.62 rad/s, x and y are in meters, and t is in seconds.(b) the wavel
BartSMP [9]

For a wave is described by y=0.0200 sin (kx - ωt) , where , ω = 3.62 rad/s, x and y are in meters, and t is in seconds, the wavelength = 2.978

<h3>How to solve for the wavelength</h3>

What is wave speed?

This is used to refer to the speed at which a wave is moving. It is the product of frequency and wave number

Given data

y=0.0200 sin (kx - ωt)

ω = 3.62 rad/s

y are in meters

t is in seconds

k = 2.11 rad/m

k = wavenumber = 2 * pi / wavelength

wavelength = 2 * pi / wavenumber

wavelength = 2 * pi / 2.11

wavelength = 2.978
