Plasma is formed by increasing the temperature of a gas until the electrons within have enough energy to break free of the positive force of attraction exhibited by the nucleus.<span> </span>
If a 12-N force is applied continuously through a distance
of 12m, then the amount of work done is
(force) x (distance) = (12 N) x (12 m) = 144 joules.
Power = (work done) / (time to do the work)
= (144 joules) / (3 sec) = 48 joules/sec = 48 watts.
We don't care what purpose the force was used for,
or how much friction was involved.
It would be hardness that in general best describes malleability, since malleability is a measurement of an objects ability to form and take difference shapes.
Answer:
Your answer is: D) 110N
Hope this helped : )
Explanation:
In order for the wood to sink, it's specific gravity must equal 1 (or greater).
Specific gravity = .6 kg/m^3= Mass/volume
F (Newtons or kg x m/s^2) = Mass*9.8m/s^2.
Therefore, Mass = 160 N / 9.8 m/s^2= 16.32 kg
Volume = Mass/Specific Gravity = 16.32kg/.6 kg/m^3 = 27.2 m^3
Desired Specific gravity = 1 = (Mass + additional force/9.8m/s^2)/Volume = (16.32 kg +X / 9.8m/s^2)/27.2m^3
Solving for the additional force: X = 106.66...N
The answer is D, 110 N will be required to sink the block of wood.
To solve the problem, it will be necessary to define the rotational and translational kinetic energy in order to determine the relationship between the two. Rotational energy is defined as,
Here,
I = Moment of Inertia
= Angular velocity
Now the translational energy will be,
Here,
m = Mass
v = Velocity
Therefore the relation between them will be,
Applying the moment of inertia of a sphere we have,
Therefore the ratio will be 0.01077
