Answer: A
Explanation: How large a parachute is (in other words, the parachute's surface area) affects its air resistance, or drag force. ... In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
1) According to the law of conservation of momentum ..
<span>Horiz recoil mom of gun (M x v) = horiz. mon acquired by shell (m x Vh) </span>
<span>1.22^6kg x 5.0 m/s = 7502kg x Vh </span>
<span>Vh = 1.22^6 x 5 / 7502 .. .. Vh = 813 m/s </span>
<span>Barrel velocity V .. .. cos20 = Vh / V .. ..V = 813 /cos20 .. .. ►V = 865 m/s </span>
<span>2) Using the standard range equation .. R = u² sin2θ /g </span>
<span>R = 865² x sin40 / 9.80 .. .. ►R = 49077 m .. (49 km)</span>
Answer: Option (B) is the correct answer.
Explanation:
More is the human population then more will be the consumption of both natural and man-made resources.
For example, consumption of land, fuel, water, chemicals etc will be there due to increase in population.
Thus, we can conclude that the sentence an increase in people would likely result in an increase in waste best explains how human population growth affects the production of waste.
She covered 25 meters in 10 seconds.
Her SPEED is (25 m) / (10 s) = 2.5 m/s .
We don't have any way to describe her velocity, because we don't know what DIRECTION she ran.
