Extinct because it will die if it don’t adapt or evolve to its surroundings
Length
The metric unit used to measure length in International System (SI) is meter and it is represented by letter m.
Length can be measured by a metric scale.
Mass
The metric unit used to measure Mass in International System (SI) is Kilograms and it is represented by letter Kg.
Mass can be measured by an instrument called Balance.
Volume
The metric unit used to measure Volume in International System (SI) is Liter and it is represented by letter l.
Volume can be measured by a container called graduated cylinder.
Temperature
The metric unit used to measure Temperature in International System (SI) is Kelvin and it is represented by letter K.
Temprature is measured by most common divice called thermometer.
Answer:
0.51 m
Explanation:
From the question,
Applying coulomb's law,
F = kqq'/r²....................... Equation 1
Where F = Electrostatic force, q = magnitude of the first charge, q' = magnitude of the second charge, r = distance between the two charges, k = coulombs constant
making r the subject of the equation
F×r² = kqq'
r² = kqq'/F
r = √(kqq'/F).................. Equation 2
Given: F = 4.2×10⁻⁴N, q = q' = 1.1×10⁻⁷C, k = 9×10⁹ Nm²/C²
Substitute these values into equation 2
r = √(9×10⁹×1.1×10⁻⁷×1.1×10⁻⁷/4.2×10⁻⁴)
r = √(1.1×1.1×9/4.2)(10⁹×10⁻⁷×10⁻⁷×10⁴)]
r = √(2.59×10⁻¹)
r = √(0.259)
r = 0.508
r ≈ 0.51 m
Answer:
The entropy of the gas increases
Explanation:
The entropy of an isolated system tends to increase. but this gas gas is not isolated. It has a piston perfoming work on it and it can exchange heat with it's surroundings.
While the system's entropy decreases, the surroundings' entropy increases, and the entropy change of the universe, which is the sum of the entropy changes of the system and the surroundings, will be equal or greater than zero.
