a,b,c is your answer light and sound are not considered matter and heat is energy created from matter and electricity is particles moving basically therefore electricity is matter hope this helps
Floating. When you have no gravity you have nothing to be pushing you down to the floor so that would be an example of no gravity pushing on you.
For the purpose we will use the following equation for potential energy:
U = m * g * h
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth).
When we plug values into the equation, we get following:
U= 65.7kg * 9.8 N/kg *135m = 86921.1 J = 86.92 kJ
Answer: boyles law I’m pretty sure
In order to solve this problem, it is necessary to apply the concepts related to the Pressure according to the Force and the Area as well as to the pressure depending on the density, gravity and height.
In the first instance we know that the pressure can be defined as
Where
F= Force
A = Mass
In the second instance the pressure can also be defined as
Where,
Density of Fluid at this case Water
g = Gravitational Acceleration
h = Height
If we develop the problem to find the pressure then,
Through the second equation we can find the depth to which it can be submerged,
Re-arrange to find h
