Answer:
C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.
Explanation:
At constant temperature, pressure and volume are inversely related.
P V = constant
As the pressure increases, the gas compresses, the particles come closer reducing the volume of gas.
As we know, with decrease in volume, density increases.
Thus, the pressure of a gas is directly related to concentration of particles. Increase in pressure causes increase in concentration of the particles.
Answer: C. Tissue Paper
Explanation:
When we talk about objects that are illuminated by a light source, they are classified according to the amount of light they let through them, as follows:
Transparent bodies: Those who let in almost all the light that incides them. Therefore, the intensity of the incident light is very similar to that transmitted. For example: Clear Glass
Opaque bodies: Those who do not let the light pass. For example: Cream Cheese and Orange Juice
Translucent bodies: Those that let in a portion of the incident light. That is, they let approximately half of the light that falls on them pass through. For example: Tissue Paper

Answer:
velocity zero and acceleration negative
Explanation:
According to the directions taken in the vector analysis, the direction which is upwards taken as positive, the direction which is downwards is taken as negative.
The direction which is rightwards taken as positive and the direction which is leftwards taken as negative.
here, ball throws vertically upwards and it attains a maximum height. At maximum height the magnitude of velocity is zero but the acceleration is always acting downwards so it is taken as negative in sign.
Answer:
C. Experimental Probability
Explanation:
The empirical (or experimental) probability means the event that arise and depend how the event arise when the data is collected from an experiment in a more no of trials. It would be depend upon the direct observation. Here each and every observation in an experiment is known as trial
So the probability that depend upon the experiment observation is known as the experimental probability
Hence, the option c is correct
