Answer:
freezing point of alcohol is - 117°C. So, it can measure the temperature of the very cold region.
Explanation:
Alcohol thermometer is preferred for a very cold region because its freezing point of alcohol is - 117°C. So, it can measure the temperature of the very cold region.
Answer:
The 5.53 moles of virus in an oil tanker.
Explanation:
Given:
Mass of virus mg
Mass of oil kg
From the formula of moles,
Moles of viruses is given by,
Mass of 1 oil tanker divide by mass of 1 mole of virus,
Therefore, the 5.53 moles of virus in an oil tanker.
Answer:velocity=
Explanation:
We shall use conservation of energy to solve this problem
we have
Potential energy of King Kong at top of building = His kinetic energy at the bottom
Potential energy of an object = = 20000 kg
Where m is mass of an object(20000 kg)
g is accleration due to gravity = 9.81
h is the height above the surface of earth = 1450 feet = 441.96 meters
Applying values we get
......................(i)
Now Kinetic energy is given by
.......................(ii)
Equating i and ii we get
86712.552 =
Applying values we get

Answer:
The value is
Explanation:
From the question we are told that
The amount of force a square meter of an aircraft wing should produce is
The air speed relative to the bottom of the wing is
The air level density of air is
Gnerally this force per square meter of an aircraft wing is mathematically represented as
Here u is the speed air need to go over the top surface to create the ideal lift
A is the area of a square meter i.e
So
=>
