Biologists found a new species of pale shrimp at the world’s deepest undersea vent, the Beebe Vent Field. The vent is 3.1 miles below the sea’s surface. Approximately how many kilometers below the sea’s surface is the vent? (1 kilometer `approx` 0.6214 miles)

The correct Answer is:
D
It’s given that 1 kilometer is approximately equivalent to 0.6214 miles. Let x be the number of kilometers equivalent to 3.1 miles. The proportion `"1 kilometer"/"0.6214 miles"="x kilometers"/"3.1 miles"` can be used to solve for the value of x . Multiplying both sides of this equation by 3.1 yields `3.1/0.6214=x` , or `x approx 4.99`. This is approximately 5 kilometers.
Choice A is incorrect and may result from misidentifying the ratio of kilometers to miles as miles to kilometers. Choice B is incorrect and may result from calculation errors. Choice C is incorrect and may result from calculation and rounding errors.

A square field measures 10 meters by 10 meters. Ten students each mark off a randomly selected region of the field, each region is square and has side lengths of 1 meter, and no two regions overlap. The students count the earthworms contained in the soil to a depth of 5 centimeters beneath the ground’s surface in each region. The results are shown in the table below. Which of the following is a reasonable approximation of the number of earthworms to a depth of 5 centimeters beneath the ground’s surface in the entire field?

A large tank is filled waith water (density = 10^(3) kg//m^(3) ). A small hole is made at a depth 10 m below water surface. The range of water issuing out of the hole is R on ground. Approximately what extra pressure must be applied on the water surface so that the range becomes 2R (take 1 atm = 10^(5) Pa and g = 10 m//s^(2) )

A circus wishes to develop a new clown act. Fig. (1) shows a diagram of the proposed setup. A clown will be shot out of a cannot with velocity v_(0) at a trajectory that makes an angle theta=45^(@) with the ground. At this angile, the clown will travell a maximum horizontal distance. The cannot will accelerate the clown by applying a constant force of 10, 000N over a very short time of 0.24s . The height above the ground at which the clown begins his trajectory is 10m . A large hoop is to be suspended from the celling by a massless cable at just the right place so that the clown will be able to dive through it when he reaches a maximum height above the ground. After passing through the hoop he will then continue on his trajectory until arriving at the safety net. Fig (2) shows a graph of the vertical component of the clown's velocity as a function of time between the cannon and the hoop. Since the velocity depends on the mass of the particular clown performing the act, the graph shows data for serveral different masses. From figure 2, approximately how much time will it take for clown with a mass of 60 kg to reach the safety net located 10 m below the height of the cannot?
