Answer:
The box will experience an acceleration.
Explanation:
Here, 2 N and 3 N forces are acting opposite to each other. In this case, the net force experience by the box would be (3-2)N = 1 N towards right. Since acceleration is directly proportional to the net force, therefore the box will experience an acceleration.
For a concave mirror, the radius of curvature is twice the focal length of the mirror:
where f, for a concave mirror, is taken to be positive.
Re-arranging the formula we get:
and since the radius of curvature of the mirror in the problem is 24 cm, the focal length is
Answer:
<h3>8. </h3>
m= 0. 113 kg
W = 1.1074 N
g = 9.8 m/ s²
<h3>9. </h3>
m= 870 kg
W = 8526 N
g = 9.8 m/s²
<h3>10.</h3>
a) weight on earth:
weight = mass × acceleration due to gravity (g)
<em>g</em><em> </em><em>on</em><em> </em><em>earth</em><em> </em><em>=</em><em> </em><em>9</em><em>.</em><em>8</em><em> </em><em>m</em><em>/</em><em>s</em><em>²</em>
W = 75 × 9.8
<u>W</u><u> </u><u>= </u><u>7</u><u>3</u><u>5</u><u> </u><u>N</u>
b) g on Mars
285 = 75 × g
g = 285/ 75
<u>g = 3.8 m/ s²</u>
