Question 5 of 10 One tool scientists use to learn about the weather is radar.
To use radar, a weather tower sends out radio waves and
then detects the waves that are reflected back to the
tower.
If a great number of radio waves are reflected back from a particular area,
what does that tell scientists about the weather in that area?
A. There is a light sprinkling of rain in the area.
OB. There is going to be a drop in air pressure in the area.
OC. There is a large amount of rain or snow in the area.
OD. There is only sunshine in the area, with no clouds

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
