Aquimedes' principle allows to find the result for the apparent weight of the steel sphere is:
- Apparent weight is: = 369.77 N
<h3>Archimedes' principle
</h3>
The thrust of a fluid on a body is given by Archimedes' principle which states that equal to the weight of the displaced liquid.
B =
Where B is the buoyancy, p the density of the liquid, g the acceleration due to gravity and V the volume of the liquid.
In the attachment we see a free body diagram of the system, which is a representation of the forces without the details of the bodies.
= W- B
The volume of the liquid is the same as the volume of the sphere.
Let's substitute.
Let's calculate.
.
In conclusion, using Aquimedes' principle, we can find the result for the apparent weight of the steel sphere:
- Apparent weight is:

Answer:
*The increase in thermal energy the maximum emission of radiation changes according to Wien's law
*The increase in thermal energy he intensity of the energy increases significantly, proportional to the fourth power of the temperature
Explanation:
When bodies heat up, the vibrations of their molecules and atoms increase, due to the energy, therefore the internal energy (Temperature) of the body also increases.
The increase in thermal energy relaxes in an increase in body temperature, when this happens the maximum emission of radiation changes according to Wien's law that gives a shift towards the visible as the temperature increases.
Furthermore, the intensity of the energy increases significantly, in a curve described by the Planck expression.
These increases are proportional to the fourth power of the temperature
P = σ A e T⁴
Answer:
Below
Explanation:
To find the wave speed of a wave you can use this formula :
wavespeed (v) = (frequency) x (wavelength λ)
Plug in our values :
v = (10Hz) x (2m)
v = 20 m/s
Hope this helps!
