Two students designed an experiment to study the effect of solar radiations on four cities of earth. they used a globe to represent earth and a light bulb to represent the sun. the four cities were labeled a, b, c, and d on the globe at the latitudes shown in the chart below. city latitude a 33° 53' s b 64° 03' n c 39° 56' n d 2° 09' s the students moved the globe slowly around the light bulb in an elliptical orbit. based on the experiment, the students are most likely to conclude that the least variation in seasons will be experienced at city a city b city c city d

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

State the following: boyle's law and charle's law

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
