Determine the power output of a 2.0 g bee walking straight up a windowpane at 3.4 cm/s.
• No option is correct
00.67 mW
•6.2 mW
• 0.32 mW
• 2.3 mW
To determine the power output of the bee, we need to calculate the work done by the bee on the windowpane per unit time.
First, let's calculate the force exerted by the bee:
F = m * a
where m = mass of the bee = 2.0 g = 0.002 kg
a = acceleration due to gravity = 9.8 m/s^2
F = 0.002 kg * 9.8 m/s^2
F = 0.0196 N
Next, let's calculate the work done by the bee per unit time (power):
Power = Force * Velocity
Power = 0.0196 N * 0.034 m/s
Power = 0.0006664 W or 0.67 mW
Therefore, the correct option is:
• 0.67 mW
