Answer:
8.8 kN
Explanation:
V = 2 m³, W = 40 kN, SG = 1.59
Bouyant force N = 1.59 * 1000 kg/m³ * 9.81 N/kg * 2 m³ = 31.2 kN
So the weight becomes 40 - 31.2 = 8.8 kN
False ,it does not only associate with motion of object
<h3><u>Answer;</u></h3>
Light bounces off of the mirror and then appears to come from behind the mirror.
<h3><u>Explanation;</u></h3>
- <u><em>Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.</em></u>
- <em><u>When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.</u></em>
- The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen.
