Answer:
F = 1618.65[N]
Explanation:
To solve this problem we use the following equation that relates the mass, density and volume of the body to the floating force.
We know that the density of wood is equal to 750 [kg/m^3]
density = m / V
where:
m = mass = 165[kg]
V = volume [m^3]
V = m / density
V = 165 / 750
V = 0.22 [m^3]
The floating force is equal to:
F = density * g * V
F = 750*9.81*0.22
F = 1618.65[N]
<span>The Balmer series or Balmer lines in atomic physics, is the designation of one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is calculated using the Balmer formula, an empirical equation discovered by Johann Balmer in 1885. this is all I know sorry</span>
Explanation:
In physics, the motion is the change in position of an object with respect to its surroundings in a given interval of time. The motion of an object with some mass can be described in terms of the following:
distance
displacement
speed
velocity
time
acceleration
Electrical energy, a form of kinetic energy results in a flow of electrons.
<u>Explanation:
</u>
Any kind of energy related to flow or motion of objects or particles falls under the category of kinetic energy. When an object undergoes motion or flow, it will exhibit velocity leading to kinetic energy, or energy utilized from the force applied for the motion.
In this case, the electrons will flow between the molecules due to the electric current supplied to it leading to the electrical energy, the flow of electrons generate current in opposing direction to the flow of electrons. Thus, current can be produced due to the flow of electrons on applying electrical energy.
