Clouds are not stars planets become stars not clouds we can see clouds so it does not become clouds only planets do because we cannot see planets but we can see Clouds up in the sky.

Hope this helps! Make sure if you have any questions type it in

Which term defines the amount of mechanical work an engine can do per unit of heat energy it uses? A. specific heat B. conductiv

KengaRu [80]

Answer:

Efficiency

Explanation:

The amount of mechanical work an engine can do per unit of heat energy it uses is called its efficiency.
It is also defined as the output divided by the total electrical power consumed.
In terms of heat, efficiency of engine is given by :

$\eta=1-\dfrac{Q_o}{Q_i}$

$Q_o\ and\ Q_i$ are output heat and input heat respectively.

Hence, the correct option is (d) "efficiency"

In a drill during basketball practice, a player runs the length of the 30-meter court and back. The player does this three times

Sergeeva-Olga [200]

Answer:

0 m/s

Explanation:

Average velocity of an object is given by the net displacement divided by time taken. Displacement is equal to the shortest path covered by the object.

In this problem, a player runs the length of the 30-meter court and back. The player does this three times in 60 seconds.

As the player runs the court and returns to the original point. It would mean that the shortest path covered is 0.

Average velocity = displacement/time

v=0/30

v = 0 m/s

Hence, the correct option is (1).

Sand is poured at a constant rate of 75.5 g/s into a 0.540-kg bucket resting on a scale. If sand is landing in the bucket with a

worty [1.4K]

Answer:10.961 N

Explanation:

Given

mass flow rate in bucket is $\dot{m}=75.5 g/s$

mass of bucket $m=0.540 kg$

velocity of sand $v=3.70 m/s$

Force acting on bucket due to incoming of sand is given by

$F=\frac{\mathrm{d} m}{\mathrm{d} t}v$

$F=75.5\times 10^{-3}\times 3.7=279.35\times 10^{-3} N$

Now weight of sand and bucket when 0.55 kg sand is Present in bucket

$W_1=(0.54+0.55)\times 9.8$

$W_1=1.09\times 9.8=10.68 N$

Total reading on scale will be addition of weight and force acting by incoming sand

$Reading =10.68+0.279=10.961 N$

What does the measurement 6.5 V represent?

WITCHER [35]

I'm not sure.
Where did you see it ?

If you saw it on a voltmeter, then it stands for "6.5 volts".
It tells you that the 'potential difference' or 'electromotive force'
between the two points connected to the meter is 6.5 volts.

-- If a 1-ohm resistor were connected between those two points,
then 6.5 coulombs of charge would move through the resistor every
second. We would say that the "current" through the resistor is
6.5 Amperes, or "six'na half amps".

-- Each coulomb of charge (6.25 x 10¹⁸ electrons) that moves from
one of those points to the other one either gains or loses 6.5 joules
of energy, depending on which direction it moves.

-- So the resistor would need to shed heat somehow, at the rate of
6.5 watts (6.5 joules per second). If it couldn't do that, then it would
go through an interesting series of changes. It would get warm, then
get hot, then glow cherry red, then glow bright red, then glow orange,
then glow bright yellow, then make a sound like a "POP". Then it would
break in the middle, and a little wisp of smoke would come out of it.
The two halves of the resistor would sink, sag from their wires, and
the current between the two points would stop.

We would say that the resistor had "fused", "failed", "melted", "burned out",
or "bought the farm" ... all because it couldn't get rid of heat fast enough.
