The stagnation pressure of air in a mach 0.8 wind tunnel equals 900 kpa. a 1.0-cm diameter sphere position in the wind tunnel has a drag coefficient of 0.95. determine the drag force on the sphere in newtons.

answer: question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
