Answer:
1 × 10² J
Step-by-step explanation:
Given data
- Speed (v): 57.7 m/s
- Mass (m): 0.06 kg
2 oz × (1 kg/35.274 oz) = 0.06 kg
The work exerted by the player is equal to the kinetic energy (K) adquired by the ball.
K = 1/2 × m × v²
K = 1/2 × 0.06 kg × (57.7 m/s)²
K = 1 × 10² J
Answer:
They encircle the planet times.
Step-by-step explanation:
Consider the provided information.
We have 2.5 mole of dust particles and the Avogadro's number is
Thus, the number of dust particles is:
Diameter of a dust particles is 10μm and the circumference of earth is 40,076 km.
Convert the measurement in meters.
Diameter:
If we line up the particles the distance they could cover is:
Circumference in meters:
Therefore,
Hence, they encircle the planet times.
