Value of power output generated by the fly, when it walks straight up a windowpane is 0.35 Watts.

What is electric power?

Electric power is the power or energy transmitted by a electric source or circuit per unit time. It can be given as,

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

Here, (w) is the work done and (t) is time taken. As the work done on a body is the product of force and distance of body, Therefore,

$P=\dfrac{Fd}{t}$

Here, (F) is the force and (d) is distance. As the ratio of distance to the time is the velocity of the body. Thus,

$P=\dfrac{Fv}{t}$

The mass of the fly is 1.5 gram and the speed of the fly is 2.4 cm/s.

The power output of the fly as it walks straight up a windowpane at if find out using the above formula as,

$P=0.0015\times9.8\times0.024\\P=0.00035\rm kW\\P=0.35\rm W$

Thus, value of power output generated by the fly, when it walks straight up a windowpane is 0.35 Watts.

Answer from: tatilynnsoto17

Power output, P = 0.35 watts

Explanation:

It is given that,

Mass of the fly, m = 1.5 g = 0.0015 kg

Speed of the fly, v = 2.4 cm/s = 0.024 m/s

We have to find the power output of the fly. Power output is given by :

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

And W = F.d

d = distance traveled

$P=\dfrac{F.d}{t}$

Since, v = d /t

So, P = F . v

$P=mg\times v$

$P=0.0015\ kg\times 9.8\ m/s^2\times 0.024\ m/s$

P = 0.00035 watts

or P = 0.35 watts

Hence, this is the required solution.

Answer from: Quest

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
