ULU, 10.JJ.JLI a The size of a cell is typically found by capturing an image under a microscope then using software to measure its diameter. Two cells are measured using this method: Cell E: 4.5 x 10 centimeters Cell F: 7.4 x 10-4 centimeters How many times larger is the diameter of cell E than the diameter of cell F? Write your answer in standard notation, rounding to the nearest tenth. Answer: Submit Answer attempt 1 out of 2

If nth division of main scale coincides with (n+1)th division of vernier scale and main scale division is equal to a mm, then Least count of Vernier calliper is 0.1 mm for a = 1 mm and n = 9 Least count of Vernier calliper 0.1 mm for a = 2 mm and n = 19 = If value of n increases, then least count will also increase If value of n increases then least count will also decrease

011 10.0 points To win the game, a place kicker must kick a football from a point 34 m (37.1824 yd) from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 20 m/s at an angle of 45.5° from the horizontal. The acceleration of gravity is 9.8 m/s?. By how much vertical distance does the ball clear the crossbar? Answer in units of m.

While Newton's Second Law often deals with formulas and numerical calculations, there exist one very important nonnumerical convention that must be appreciated and adhered to. On September 23, 1999, Mars Climate Orbiter--a $125 M space mission--was lost when a small rocket was fired to adjust entry to the Mars atmosphere. Unfortunately, one operator assumed the thrust value was given in English units when actually NASA specifications gave it in metric units. This is an example of consequences if the MKS convention is not precisely honored. What does the MKS convention designates the following?
