Answer:
The terminal speed of his is 137.68 m/s.
Explanation:
Given that,
Mass of skydiver = 78 kg
Area of box
Drag coefficient = 0.80
Density of air
We need to calculate the terminal velocity
Using formula of drag force
Where,
= density of air
A = area
C= coefficient of drag
Put the value into the formula
Hence, The terminal speed of his is 137.68 m/s.
Answer:
Poke or kick the boxes. The sand box is the one that resists the most
Explanation:
The one that resists the most a change in motion (inertia) is the one with the greater mass—the one filled with sand. Since we cannot open the boxes or perform any weight measurement we can distinguish them by their inertia. Sand has greater mass and thus greater inertia
Answer:
The square of orbital period is proportional to the cube of the semi-major axis.
Explanation:
I just took the quick check
I’m not entirely sure tbh
When your procedure is accurate, your results will have a smaller margin of error. This is important because you will know what variables influenced ur results.
