Hello!
Use the formula:
W = Fd
Replacing:
W = 300 N * 300 m
Resolving:
W = 90000 J
The work is <u>90000 Joules.</u>
Mechanical advantage is the ratio of output force to input force of a machine.
hope this helps and have a great day :)
Answer:
The atmospheric pressure and boiling point are directly proportional
Increasing atmospheric pressure increases the boiling point also
Explanation:
The atmosphere contain molecules that are in constant motion. They exert a downward force on a liquid’s surface. The higher the air pressure, the harder it is for the liquid to evaporate. Therefore, the boiling point of a solvent or liquid is affected by the atmospheric pressure and boiling point is raised.
A liquid in a high pressure environment boils at a higher temperature.
When placed in a lower pressure environment it boils at a lower temperature.
Answer:
T=9.4 N
Explanation:
We are given that
Mass of wire,m=16.5 g=
kg
1 kg=1000g
Length of wire,l=75 cm=
m
1 m=100 cm
Wavelength of transverse wave=
m
Frequency=
Mass per unit length=
Where
frequency of wave
=Wavelength of wave
Speed of wave=v
Using the formula
Using the formula
Hence, the tension,T=9.4 N
