Answer:
b : 60m
Explanation:
when a plane mirror is placed horizontally on a level ground at a distance of 60m from the top of tower as shown in figure. a/c to question, The top of tower and its image in the mirror subtend an angle of 90° at the eyes. so, angle made by top of tower and horizontal line is 45° as

Newton's Second law of motion is
F = m * a ( force = mass * acceleration).
So if a is constant then a = F 1 / m1 and a = F2 / m2 then
F1 /m1 = F2 / m2 and if m1 > m2 then
F1 must be greater than F2.
Answer is C.
<span>Pros: Current biotechnology studies are used worldwide to solve problems such as disease as well as better detect illnesses and treat them with specifically engineered cures that would not be available in the past. Biotechnology also includes creating more fuel efficient ways to power transportation. A product from this field of science is biofuel. This altered type of fuel is used to reduce greenhouse gas emissions that can harm the ozone layer. Biotechnology is also used to create enhanced crops that are less susceptible to insects or diseases.
Cons: </span><span>While this technology can improve the resilience of crops, they are more expensive for farmers. The “biotech” seed can also become resistant to weed killer and can overgrow and ruin normal seeds. Along the same lines, diseases can become resistant and unresponsive to antibiotics because they are overprescribed and misused. Plants affected by biotechnology or engineering may have specific allergens than can affect food sensitive people.</span>
