Lower temperature

Let's verify

  • Pressure=P
  • volume=V
  • Temperature=T

As per Boyles law

\\ \rm\Rrightarrow V\propto \dfrac{1}{P}

As per Charles law

\\ \rm\Rrightarrow V\propto T

\\ \rm\Rrightarrow T\propto \dfrac{1}{P}

So

At higher altitudes lower the pressure so lower the temperature

A car travelling at 50m/s produces a force of 200N. What is the power of the engine in kilowatts(KW).
Zina [86]

Answer:

10 kilowatts or 10,000 kw

Explanation:

Power = Force × Velocity

Given that:

Velocity of car is 50 m/s

The force is 200N

The power would be:

P = 200 × 50

P = 10,000 W

Notice that it only reaches watts because of the unit of the velocity is m/s. Standard unit to make Kw is km.

Since:

1 kw = 1000 w

10 kw = 10000 w

Credits to the person below me for correction.

How many electrons does an element have if its atomic number is 20
olga55 [171]

Answer:

20 electrons

A neutral atom with atomic number 20 will have 20 electrons.

The atomic number is, by definiton, the number of protons in an atom's nucleus but for a neutral atom it's also equal to the number of electrons. Each element has a different, unique number of protons that determines its identity.
