Answer:
Option A, Boyle's law
Explanation:
The complete question is
Pressure and volume changes at a constant temperature can be calculated using
a. Boyle's law. c. Kelvin's law.
b. Charles's law. d. Dalton's law.
Solution
In Boyle’s law, the gas is assumed to be ideal gas and at constant temperature. With these two conditions fixed, Boyle’s established that volume of gas varies inversely with the absolute pressure.
The basic mathematical representation of this phenomenon is as follows -

OR

Where P is the pressure of ideal gas, V is the volume and k is the constant of proportionality.
Hence, option A is correct
Answer:
mucilage can detect objects the size of millimeters, whereas humans can only detect objects larger than centimeters
Explanation:
The human ear can detect sound in the range of 20 to 20000hz, we are asked to find the mid-range wavelength of the ear at f = 10000 Hz
let's use the relationship between wave speed, wavelength and frequency
v = λ f
λ= v / f
λ = 343/10000
λ = 3.43 10⁻² m
the sound range of a bat is between 25 10³ Hz and 100 10³ Hz, they also ask for the wavelength in the middle range
f = (100 10³ + 25 10³) / 2
f = 62.5 10³ Hz
λ = 343 / 62.5 10³
λ = 5.5 10⁻³ m
Therefore the size of the object that a bat can detect is much smaller than the size that a human can detect, therefore the bat is capable of detecting insects, but humans.
The mucilage can detect objects the size of millimeters, whereas humans can only detect objects larger than centimeters
Answer:
Newton's first law of Inertia.
Explanation:
This explains how a magician is able to remove a tablecloth from under dishes and glasses on the table without disturbing them. Because of the mass of the object, it remains in inertia. The Tablecloth, in this trick, is slippery so that it does not have any real friction with glasses and dishes.
The force of gravity that the sun
exerts on a planet is directed toward the sun. I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.

The distance covered is 8 blocks, the displacement is 2 blocks up
Explanation:
- Distance is a scalar quantity measuring the total length of the path covered by an object, regardless of the direction of its motion
- Displacement, on the other hand, is a vector quantity equal to the difference between the final position of motion and the initial position of motion. Its magnitude is equal to the shortest distance in a straight line between the initial and final point of motion.
In this problem, Kim walks the dog 5 blocks up and 3 blocks down:
- The distance is just the total length of the path taken, therefore:

- The displacement is a vector connecting the final point to the initial point. Since Kim walks 5 blocks up and 3 blocks down, her final position is
x = +5 +(-3) = +2
Which means, 2 blocks up. Therefore, the displacement is 2 blocks up.
