TRUE OR FALSE : Boyle’s law states that, as the pressure of a gas increases, the volume decreases.

Answers

Answer 1
Answer:
At first glance, this statement seems to be true.  But after about a
microsecond of further consideration, one realizes that the statement
would actually set Boyle spinning in his grave, and is false.

Boyle's law states that there is a firm relationship among the pressure,
temperature, and volume of an ideal gas, and that you can't say anything
about how any two of these quantities depend on each other, unless you
also say what's happening to the third one at the same time.

As the pressure of an ideal gas increases, the volume will decrease in
direct proportion to the volume, IF THE TEMPERATURE OF THE GAS
REMAINS CONSTANT.

If you wanted to, you could increase the pressure AND the volume of an
ideal gas both at the same time.  You would just need to warm it enough
while you squeeze it.

There are ____ molecules of air at high elevations, so air pressure is less.a. fewer
c. more
b. the same number of

Answers

The correct answer is (a.) fewer. there are fewer air molecules at high elevations. The air pressure is less at a higher elevation which also mean that there will a fewer air molecule than it is on the lower level.

d. The ...

Answers

Answer:

B) The larger one accelerates at 3.33 m/s² while the smaller one accelerates at 100 m/s².

Explanation:

Parameters given:

Mass of larger asteroid = 3000 kg

Mass of smaller asteroid = 100 kg

Force of collision = 10000 N

Since both of them experience the collision force, we can find how that force causes them to accelerate by using the formula of force:

F = m*a

=> a = F/m

For the larger one,

a = 10000/3000 = 3.33 m/s²

For the smaller one,

a = 10000/100 = 100 m/s²

 There's really no such thing as the force of a collision.

F = M A
A = F / M

If a 10,000N net force acts on a 3,000 kg object, then the object's
acceleration is (10,000N / 3,000kg) = 3-1/3 m/s² for as long as the
force on it persists, and zero after that.

If a 10,000N net force acts on a 100 kg object, then the object's
acceleration is (10,000N / 100kg) = 100 m/s² for as long as the
force on it persists, and zero after that.

Those appear to be the numbers in choice-b, but the description
of the event and the situation is misleading.

Imagine that a tank is filled with water. The height of liquid column is 7 meters and the area is 1.5 square meters (m2). What's the force of gravity acting on the column of water?

Answers

-- The volume of water is    (1.5 m² x 7 m)  =  10.5 m³

   10.5 m³  =  10,500 liters

   Water mass  =  (10,500 liters) x (1 kg/liter) = 10,500 kg.

-- "Force of gravity on the water"

    =  Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons

-- Pressure on the bottom of the tank =

                 (102,900 newtons) / (1.5 m²)

             =      68,600 nt/m²  =  68,600 pascal .

your answer is 102,900 N

During a thunder storm, movement of water molecules within clouds creates friction which causes the bottom of the clouds to become negatively charged. This means that the bottom of the cloud and the ground begin to act like parallel plates. Once the electric field between the clouds and the ground becomes larger than 3.0 x 10^6 N/C, lightning will strike. a. If the bottom of the cloud is 150 m above the ground, determine the electric potential difference between the ground and the cloud.

Answers

the distance between the charges, or so called infinite charge plates is 150 m, the magnitude of the electric field is 3 x 10^6 N/C and we need to find the voltage, or potential energy, the electric field magnitude is defined as:

E = V/d

therefore, the potential is:

V = E * d

so we have:

V = 3 x 10^6 * 150 = 450 x 10^6 J/C (or volts)

that is the electrical potential difference.
