A) You can drop hammer and a feather, both will reach ground at the same time ( it was actually done in Apollo mission)
b) i. Yes, it is similar to weightlessness experienced by astronauts
ii. The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall" in roller coaster, accelerating downward at the acceleration of gravity, then you are not being supported.
Just like astronauts in space feel no force of support that we on earth feel due to gravity.
-3(2)(-4)+4(2)-3=24+8-3=29
The value is 29
Answer: 4/52
Step-by-step explanation:
Because thwre are 4, fives in a normal deck so the probability would be 4/52 not simplifyed
Answer: 9pi
Step-by-step explanation:
Flip the fraction to make the -3 exponet positive then it will be 9x^5/3x^3 which the answer would then be 3x^2
