1 pound (lb) = 453.592 g
Therefore, 5.4 pounds will be equivalent to 5.4 × 453.592 = 2449.397 g
1 cubic inch = 16.387 cubic cm
Therefore, 13.6 cubic inches will be equivalent to 13.6 × 16.387 = 222.863 cm³
Density is given by mass divided by volume
Thus density = 2449.397 g / 222.863 cm³
= 10.991 g/cm³
Answer:As an equation, the tangential velocity is the distance, 2π r, divided by the time, T. Thus, A point on the circle moves a distance 2π r in a time T. We can extend our equation by looking at a few ideas. These concepts include the angular speed, ω, and the frequency, f. The angular speed, ω, is a speed of rotation.
Explanation:
i know
1) The electric field between the two plates is
. The potential difference between the plates is given by
where d is the separation between the plates. By using
we find
2) The work done by the electric field to move the electron by that distance is equal to the variation of electric potential energy of the electron:
where e is the electron charge. By substituting numbers, we find
Answer:
Explanation: w= mgh
W= pressure * volume
Pressure= density *gravity *height
Pressure = 1000*9.8*6
Pressure= 58860N/m^2
Work = 58860*6
Work= 353160j
Work = 353.16kj
Mass divided by volume is density, while mass times density is volume. you cannot calculate density without volume and you cannot calculate volume without density.
i believe that's the answer.
oh gosh i didn't realize my middle school education involved high school stuff.
