Answer:
Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. ... Experiment can provide hints toward the structure or mathematical form of a theory and it can provide evidence for the existence of the entities involved in our theories.
The pressure exerted by a fluid solely relies on the depth or height of the fluid, its density, and the gravitational constant. These three are related in the equation:
Pressure = density x g x height
In the problem, point A is within the block inside the tank. The water above the block is assumed to be 0.6 meters. This gives a point A pressure of:
P = 1000 kg/m^3 * 9.81 m/s^2 * 0.6 m = 5,886 Pa or 5.88KPa
Answer:
Energy of ultra violet photons < Energy of radio waves
Wavelength of ultra violet photons > Wavelength of radio waves
Explanation:
The increasing order of the wavelength is given by
Gamma rays
x rays
Ultra violet rays
Visible radiations
Infrared rays
micro waves
Radio waves
So, ultra violet rays has larger wavelength than radio waves.
As we know that the energy is inversely proportional to the wavelength.
So, the energy of radio waves is more than the energy of ultra violet waves.
Energy of ultra violet photons < Energy of radio waves
Wavelength of ultra violet photons > Wavelength of radio waves

Answer:
48.7 J
Explanation:
For a mass-spring system, there is a continuous conversion of energy between elastic potential energy and kinetic energy.
In particular:
- The elastic potential energy is maximum when the system is at its maximum displacement
- The kinetic energy is maximum when the system passes through the equilibrium position
Therefore, the maximum kinetic energy of the system is given by:
where
m is the mass
v is the speed at equilibrium position
In this problem:
m = 3.6 kg
v = 5.2 m/s
Therefore, the maximum kinetic energy is:
