the answer is A. temperature
Kelvin is the standard measurement unit for temperature
the temperature at which the gas molecules exert the smallest pressure is the absolute zero in the Kelvin scale. At absolute zero the gas molecules have minimal motion.
Pressure is directly proportional to temperature of the kelvin scale.
0 K is equivalent to - 273.15 °C
Answer:
Elctromagnetic waves can travel through empty space.
Explanation:
Waves that may pass through matter or empty space are known as electromagnetic waves. The electromagnetic field, like the other basic fields, penetrates the whole universe, including the region we refer to as empty space. There are no fields in space. The medium through which electromagnetic waves travel is called the electromagnetic field.
Answer:
P = 795.77 Mpa
Explanation:
Given that,
Force exerted by the hammer, F = 10⁴ N
The nail can be considered as a circle with radius of
We need to find the pressure exerted on the wall. Pressure is equal to force acting per unit area. So
We know that, 1 MPa = 1000000 Pa
So, P = 795.77 Mpa
So, the pressure exerted on the wall is 795.77 Mpa.
Answer: DNA shapes how an organism grows up and the physiology of its blood, bone, and brains. DNA is thus especially important in the study of evolution . The amount of difference in DNA is a test of the difference between one species and another – and thus how closely or distantly related they are.
