Explanation:
The hydraulic system works on the principle of Pascal's law which says that the pressure in an enclosed fluid is uniform in all the directions. ... As the pressure is same in all the direction, the smaller piston feels a smaller force and a large piston feels a large force.
Answer:
false
Explanation:
every object will always have the force of gravity acting upon it.
Answer:
5.69 m/s.
Explanation:
The given data is as follows.
Magnetic field strength (B) = 0.65 T
Speed (v) = 4.2 m/s
Induced emf (E) = ?
Formula for emf induced at the ends of the rod of length L which is moving with a speed of v is as follows.
E = BvL
Putting the given values into the formula as follows.
.
![E_{1} = BvL = 0.65 T \times 4,2 m/s \times L\\=2.73L](https://tex.z-dn.net/?f=E_%7B1%7D%20%3D%20BvL%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3D%200.65%20T%20%5Ctimes%204%2C2%20m%2Fs%20%5Ctimes%20L%5C%5C%3D2.73L)
When magnetic field is changed to ![B_{2} = 0.48 T](https://tex.z-dn.net/?f=B_%7B2%7D%20%3D%200.48%20T)
Now, we assume that the speed be
to get the emf![E_{2} = E_{1}.](https://tex.z-dn.net/?f=E_%7B2%7D%20%3D%20E_%7B1%7D.)
Then,
![0.48 T \times v_{2} \times L = 0.65 T \times 4.2 m/s \times L v_{2} = 5.69 m/s](https://tex.z-dn.net/?f=0.48%20T%20%5Ctimes%20v_%7B2%7D%20%5Ctimes%20L%20%3D%200.65%20T%20%5Ctimes%204.2%20m%2Fs%20%5Ctimes%20L%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20v_%7B2%7D%20%3D%205.69%20m%2Fs)
we can conclude that the speed v of the rod be adjusted to reestablish the emf induced between the ends of the rod at its initial value is 5.69 m/s.
Answer:
![\sqrt{\dfrac{2g\lambda^3}{m}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cdfrac%7B2g%5Clambda%5E3%7D%7Bm%7D%7D)
Explanation:
We can write the expression here, but the point of the problem seems to be to see if you can manipulate the controls on the answer box to reproduce that expression.
![\boxed{\sqrt{\dfrac{2g\lambda^3}{m}}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csqrt%7B%5Cdfrac%7B2g%5Clambda%5E3%7D%7Bm%7D%7D%7D)
