Suppose a bicycle was coasting on a level surface, and there was no friction. What would happen to the bicycle?

2 answers:

If there is no friction and no horizontal force acting on the bicycle, then the bicycle keeps rolling at a constant speed in a straight line, until the cows come home, Dante's Inferno freezes over, and the POTUS accepts some responsibility for his words, actions, and consequences.

What is the average power developed by a motor as it lifts a 400.-kilogram mass at constant speed through a vertical distance of

Tomtit [17]

Answer:

The average power developed by a motor is 4905 Watts.

Explanation:

The average power is given by:

$P = \frac{W}{t}$

Where:

W: is the work

t: is the time = 8.0 s

First, let's find the work:

$W = F*d$

Where:

F: is the force

d: is the displacement = 10.0 m

The force is in the vertical motion, and since the movement of the mass is at constant speed the force is:

$F = mg = 400 kg*9.81 m/s^{2} = 3924 N$

Hence, the average power is:

$P = \frac{F*d}{t} = \frac{3924 N*10.0 m}{8.0 s} = 4905 J/s = 4905 W$

Therefore, the average power developed by a motor is 4905 Watts.

I hope it helps you!

Answer:

The parents and offspring all have phenotype ww. That leaves 100% probability of short wings and 0% long wings.

Explanation:

If long wings are a dominant trait, that means short wings are recessive. If two short winged flies are crossed, each of their phenotypes are ww. Therefore, each of their offspring also have phenotype ww, or short wings.
