Bicycle A with mass 40 Kg is traveling with a velocity of 4 m/s and Bicycle B with mass 20 Kg is traveling with a velocity of 2m
andrew-mc [135]

Answer:

bicycle A has a greater K.E.

Explanation:

K.E = 1/2mv²

bicycle A = 1/2 × 40 × 4² = 320J

bicycle B = 1/2 × 20 × 2² = 100J

bicycle A has a greater K.E. because it has bigger mass and moves with faster velocity

How to do the equation p1v1 = p2v2 as an equation layed out like:
KonstantinChe [14]

P1 and P2 are the pressures, and V1 and V2 are the volumes. So you take the first pressure and volume you are given and place them into the equation P1V1 so the first part of the equation would be 101000*0.5 = P2V2. You then rearrange the equation to find what you want, in this instance you would do 50500/0.25 = P2... therefore P2 = 2020000Pa or 2.02*10^6Pa

Explain why convex mirrors can only produce virtual images. Please use at least 2 content related sentences. (ref: p.471-481)
34kurt

Convex mirrors can only produce virtual images because the focal point and the center of curvature of the convex mirror are imaginary points and that cannot be reached.

<h3>What is virtual image?</h3>

This is referred to the opposite of a real image and cannot be obtained on a screen. It is formed from the  apparent divergent of light rays from a point  and not the actual one which is the major difference it has with a real image.

It is usually produced by a convex mirror because the focal point and the center of curvature of the convex mirror are imaginary points which can't be reached.
