Answer:
The total distance is 16.9 m
Explanation:
We understand work in physics as certain force exerted through certain distance. To reach that point below the water, the work done by the diver must be equal to the work done by the water's force of resistance. Therefore, we determine both work expressions and we solve the equation for the diver distance, which is the total distance between the diving board and the stopping point underwater.
Answer:
the resistance force is mg cos(-)
Explanation:
Answer:
no
Explanation:
the inertia of an object does not make it to come to rest, this is normally caused by friction
Avogadro's number is equal to 6.02 E 23
Thie means we have 6.02 E 23 marshmallows.
Assuming each marshmallow to be a small cylinder we can calculate the area of its base
Area circumference = pi*r² = pi * (0.635/2)² = 0.317 cm²
So, 6.02 E 23 marshmallows * 0.317 cm² cover a total area of
Area covered = 1.908 E 23 cm² = 1.908 E 13 km²
<span>The land area of california is 1.560 E 5 mi</span>² = 4.04 E 5 km²
If we divide the Areas >>>>
1.908 E 13 km² / 4.04 E 5 km² = 47. 227 E 6 (This is the number of times the area of California could be filled with those marshmallows)
Now for the height, we multiply this number times the height of each marshmallow
47. 227 E 6 * 2.54 cm = 119.96 E 6 cm = 1199.6 km above the surface
Use this numbers that you are given and plug them into the formule for net force
Net force= m*a (mass times acceleration)
Therefore the net force is equal to (5.5 kg)*(4.2 m/s^2)= 23.1 N
Answer: Net force= 23.1 N
