Answer:

Venus

Explanation:

Solar system has 8 planets namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Out of these the first four planets are rocky while the last four are gaseous. When you compare the size of the rocky planet with gaseous planets, gaseous planets are way too bigger than rocky planets.

Using the same information, out of the given options Venus is the correct answer as it is smaller than other three planets and has a rocky surface and atmosphere.

A piston above a liquid in a closed container has an area of 1m2. The piston carries a load of 350 kg. What will be the external

ddd [48]

The weight of the load is (mass) x (gravity)

   = (350 kg) x (9.8 m/s²)

   =    3,430 newtons .

The force on the surface of the liquid is the weight of the piston and its load.

The pressure on the surface of the liquid is (force) / (area)

   = (3,430 newtons) / (1 m²)

   = 3,430 pascals

   = 3.43 kPa

This doesn't include anything for the weight of the piston without its load,
but it's certainly the closest of the choices.

With the switch open, roughly what must be the resistance of the resistor on the right for the current out of the battery to be

jeyben [28]

Question:

Assumptions

Voltage of battery = 24 V

Resistance on the right,20Ω parallel to 10 Ω resistor

Answer:

For the current out of the battery to be the same as when the switch was opened with the switch closed, the resistance on the resistor on the right must be approximately 20/3 Ω

Explanation:

We note that the switch in the assumption is on the same line as the 20 Ω resistor.

With a voltage of 24 V, and the switch closed, we have;

Total resistance = $\frac{1}{\frac{1}{10} +\frac{1}{20} } = \frac{20}{3} \Omega$

Current out of voltage, I = Voltage/(total resistance)

= 24 ÷ 20/3 = 24 × 3/20 = 18/5 A

Therefore, with the switch opened, we get

Resistance on the right = Initial total resistance $= \frac{20}{3} \Omega$

Therefore, with the switch opened, the resistance on the resistor on the right must be approximately equal to the resultant resistance of the two resistances in parallel.

A light plane must reach a speed of 33m/s for takeoff.how long a runway is needed if the the acceleration is 3.0m/s^2

Tanzania [10]

Remark

Always write down your givens and what you want to find. The formula you use for such questions will suggest itself if you do this.

Givens

a = 3.0 m/s^2

vi = 0 I presume that's that the question assumes.

vf = 33 m/s

You want d

Formula

vf^2 = vi^2 + 2*a*d

Solution

33^2 = 0^2 + 2 * 3 * d

1089 = 6*d

d = 1089/6

d = 181.5 meters

What is. the units of velocity

natta225 [31]

Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second.
