Non-ideal behavior for a gas is most likely to be observed under conditions of a) high pressure and low temperature. b) high temperature and high pressure. c) high temperature and low pressure. d) standard temperature and pressure. e) low temperature and low pressure.
Answer:
high temperature and low pressure
Explanation:
Real gases have intermolecular forces of attraction between them hence they can be liquified. However, gases approach ideal behavior at high temperature and low pressure.
According to the kinetic theory of gases, gases molecules move at incredibly high speeds and exhibit no intermolecular interaction because the gas molecules are isolated from each other.
At high temperature and low pressure, gas molecules are found to possess maximum kinetic energy. They move with a very high velocity and have minimal intermolecular interaction between them in accordance with the proposition of the kinetic theory of gases.

difference between uniform motion and non uniform motion
Answer:
Uniform motion is a type of motion that is characterized as the motion of an object wherein the object moves in a straight line and its velocity remains unchanged along that line, regardless of the duration of time, as it occupies equal distances at equal time interval and Non-uniform motion is described as the motion of an object wherein the object moves at different speeds and does not cover the same distance at equal time intervals, regardless of the duration of the time interval.
Answer:
hope it's help you
Explanation:
In Uniform motion, the movement of a body is along the straight line with constant speed. In non uniform motion, the movement of a body is along the straight line with variable speed. In uniform motion, the body covers equal distance in an equal interval of time.
The moving bicycle moves for sometime even after stopping the paddling.why
Answer:
when you are paddling the push carry on when you paddle the hard put on the push.
Answer:
Because of inertia
Explanation:
As stated in Newton first law "An object at rest will stay at rest, an object in motion will stay in motion unless it is acted upon by a force."
For an example:
If you have a drink without a lid in a car and a car suddently the car stop, u will automatically try to catch the drink preventing it from spilling. This is because that the drink that was in motion with the car want to stay in motion, but when the car stop, the drink still wanna be in motion, that's why it will be flying off and spill if u don't catch it.
Back to the question:
if a bicyccle is in motion, it will wants to be in motion untill a force act upon it, let's say a bump or fricition.
hope this help. give me the brainliest if u can.
(Q008) Magnetic anomalies are a. found only on the seafloor. b. measured with an instrument called an inclinometer. c. defined as the angle between which a compass needle points and the longitude at that point. d. places where the magnetic field strength is either greater or less than the expected strength.
Answer: D. places where the magnetic field strength is either greater or less than the expected strength.
Explanation:
Magnetic anomaly refers to the change in the magnitude of the magnetic field of the Eatth with respect to the location's expected value.
Magnetic anomalies are places where the magnetic field strength is either greater or less than the expected strength. Therefore, the correct option is D.
What is the relation between the weight of a body and acceleraton due to gravity?
Answer:
All objects on Earth, regardless of their mass, accelerate due to gravity at the same rate - that is, 9.8 m/sec2. The weight of an object can be calculated using the formula for force - F = m * a - where F equals the weight of the object and now the acceleration (a) is the acceleration of gravity (g).
D=12000 m
T= 30min
V=?

is there any machine that is 100% efficient? why?why not
Answer:
No, it's not there.
Explanation:
For a machine to be 100% efficient, it has to be with an output which is equal to its input. But machines have an out put less than an input, hence efficiency below 100%.
1. explain the procedure undertaken if you have to measure the density of the contents of a milk carton. 2. two objects have the same mass. How about the density of the two objects?
To calculate the density of a substance, its mass and volume has to be determined. So that:
i. For the milk in the carton, its mass and volume should be known.
ii. For the two objects given in the question, their individual masses and volumes have to be determined.
Density of a substance (ρ) is the rate of the mass (m) of the substance to its volume (V). It is measure in kg/[tex]m^{3}[/tex].
i.e ρ = [tex]\frac{m}{V}[/tex]
The density of a substance can be determined once the mass and its volume have been accurately measured.
1. How to measure the density of the contents of a milk carton.
a. Determine the mass of the milk carton with its content.
b. Determine the mass of the milk carton when empty.
c. Subtract the mass of the milk carton when empty from the mass of the carton with its content. This will give the mass of the milk in the carton.
d. Using a beaker, measure the volume of the milk.
e. Divide the mass of the milk by its volume to determine its density.
2. How to measure the densities of two objects of equal mass.
a. Fill an Eureka's can or a beaker with sprout with water to its brim.
b. Slowly drop the mass into the beaker with water so as to collect the volume of the liquid displaced into another beaker.
c. The volume of the liquid displaced is the volume of the mass.
d. Divide the mass of the object by its volume to determine its density.
NB: These procedures are observed to determine the densities of the two object individually.

give scientific reasons when the body falls freely to the ground its motion as the uniform acceleration
Answer:
When an object falls freely to the ground, its acceleration is uniform. Hint: When an object falls freely on the ground, the force of the gravity works on it. So the acceleration on the object is the acceleration due to gravity. So the acceleration is uniform on the freely falling body.

The direction of applied force has to be .............. to the distance in order to say work is done
Answer:
Parallel
Explanation:
The work done is defined as the force applied on an object and the displacement in the position of the object in the direction of force.
W = F s cos A
where, F is the force, s is the displacement and A is the angle between force and displacement.
When the angle between the force and the displacement is 90 degree, the work done is zero.
To get the maximum work the angle between the force and the displacement is 0 degree.
So, to get the work done by the force the angle between the force and displacement is 0 degree that means the force and displacement is parallel to each other.
