Calculate the energy stored in a spring when it is compressed 5 mm by a 60 N force?​

Physics
1 answer:
Hunter-Best [27]3 years ago
7 0

Answer:

Explanation:

Assuming statics

The average force is (60 + 0) / 2 = 30 N

E = Fd = 30(0.005) = 0.15 J

or

k = F/d = 60/0.005 = 12000 N/m

E = ½kx² = ½(12000)0.005² = 0.15 J

How much charge is enclosed by a Gaussian surface through which the electric flux is 6.78 x 10^9 Nm^2\C.
VMariaS [17]

Answer:

q=0.06 C

Explanation:

Given that

Net flux \phi = 6.78\times 10^{9}\ Nm^2/C

Lets take charge inside Gaussian surface = q C

We know that

\phi=\dfrac{q}{\varepsilon _o}

\varepsilon _o=8.854\times 10^{-12} farads\ per\ meter

Now by putting the values in the above equation we get

6.78\times 10^{9}=\dfrac{q}{8.854\times 10^{-12}}

q=6.78\times 10^{9}\times 8.854\times 10^{-12}\ C

q=0.06 C

Therefore the net charge inside the surface will be 0.06 C.

q=0.06 C

URGENT! 50pts! Help with rotational speed questions please?
EastWind [94]
1). If you want the wheel to turn as one solid piece, then all parts of it must have the same RATE of rotation. If one part was going 2 RPM and another part was going 3 RPM, then there's no way both parts could stay hooked together. Their SPEED depends on their distance from the center, but they all have to make the same RPM. 2). The CENTRIPETAL acceleration of anything that's rotating is. m-v-squared/ R. The object's speed depends on its radius, and it's acceleration varies directly with the square of the speed. So if you move in to half the radius, the acceleration becomes 1/4 of the original value.
