3 0

Answer: D. 40

Explanation:

Power = Force * Velocity

Force = 600N

Power needs to be converted to Watts:

= 24 * 1,000

= 24,000 W

24,000 = 600 * Velocity

Velocity = 24,000/600

= 40 m/s

Argon in the amount of 0.6 kg fills a 0.05 m3 piston cylinder device at 550 kPa. The piston is now moved by changing the weights
Vinil7 [7]

Answer:

The final pressure in the device is 275 kPa.

Explanation:

Given that,

Amount of argon = 0.6 kg

Initial volume = 0.05 m³

Pressure = 550 kPa

Final volume = 2 initial volume

Temperature is constant.

We need to calculate the final pressure

Using ideal gas

P_{1}V_{1}=RT_{1}

P_{1}V_{1}=RT_{2}

Here, Temperature is constant

So, from equation (I) and equation (II)

P_{1}V_{1}=P_{2}V_{2}

P_{2}=\dfrac{P_{1}V_{1}}{V_{2}}

Put the value into the formula

P_{2}=\dfrac{550\times10^{3}\times0.05}{2\times0.05}

P_{2}=275000\ Pa

P_{2}=275\ kPa

Hence, The final pressure in the device is 275 kPa.

What is true about a circular orbit?
Sliva [168]
-- The speed of the orbiting body is the same at every point in its orbit.

-- Since a circle is the ellipse with coincident foci, the central body is
at the center of the circular orbit.

-- The radius of the circular orbit drawn from the central body to the
orbiting body sweeps out the same amount of area in every same
amount of time.

-- The forces of attraction between the central body and the orbiting body
may be electrostatic, magnetic, or gravitational.

-- The circular orbit never occurs in nature.  In the case of TV satellites
that appear 'fixed' in the sky, their orbits must constantly be adjusted to
maintain circularity and prevent them from drifting off station..

Which of the following compounds is not likely to have ionic bonds? Question 5 options: LiF NaCl CH4 MgF2
Harrizon [31]

Answer:

CH4

Explanation:

CH4 is joined together by a covalent bond, aka a bond between two non-metals. Non-metals are found on the right side of the periodic table and include Carbon (C) and Hydrogen. Although Hydrogen is technically on the left side of the table, it has the characteristics of a non-metal. Futhermore, Ionic bonds generally are between an element on the right joined with an element on the left. This is because ionic bonds want charges that will cancel out to create a neutral molecule.

example: LiF

Li→ Li+

F→F-

(Li+)+(F-)=charges cancel out.
