B because the ramp has the most mobility
Answer:
the paper ball falls faster and the unfolded paper falls at a slower rate
Explanation:
this is because gravity is pulling both objects down to the ground and hence they are falling. Both objects have the same mass and weight but the resultant force of the paper ball is smaller than that of the unfolded paper. The unfolded paper has a larger surface area and so a larger force is acted upon it, meaning there is more air resistance. This shows that the paper ball falls faster than the unfolded paper.
Answer:
it is either constant or zero
Explanation:
The correct option is SCALE.
This is because the experimental data you are interested in is mass and scale is the instrument that is used to measure mass. To use the scale, measure the mass of your water before you put it inside the sun and measure the mass again after you remove it from the sun. The difference in mass is the quantity of water that is evaporated.
There are different type of scale and the one that you use will depend on the size of the material that you want to measure.<span />
Answer:
7.06454224 Newtons
Explanation:
C = Drag coefficient = 0.8
ρ = Density of air = 1.204 kg/m³
A = Surface area = 1 m²
v = Velocity of wind = 7 min/mi = 3.83 m/s
The Drag force is given by
The drag force exerted on the runner is 7.06454224 Newtons
