The drawing shows a parallel plate capacitor that is moving with a speed of 35.6 m/s through a 3.38-T magnetic field. The velocity v is perpendicular to the magnetic field. The electric field within the capacitor has a value of 194 N/C, and each plate has an area of 8.98 × 10-4 m². What is the magnitude of the magnetic force exerted on the positive plate of the capacitor?

What is the uncertainty in the temperature difference, ΔT, between the two temperature T1 = (25.0 ± 0.5) oC and T2 = (30.0 ± 0.3) oC?

Where is the 10^11 from in the b part of the problem? From the problem, it's 1.50 × 10^8. Thank you!

1. A mole contains 6.02 * 1023 particles (atoms, molecules, etc.). If you wanted to reach an unkown planet (4.367 light-years away) by creating a strand of carbon atoms (0.3 nm diameter), how many moles of carbon would you need? (Note: 1 light-year = 9.46 * 1012 km)

How do I figure which values could and could not, be used for both of the questions listed in the picture.

Helpful information: (1) An alpha particle is a helium nucleus, (2) e = 1.6 × 10-¹⁹ C, (3) k = 9.0 × 10⁹ Nm² C-2, (4) 1nm = 1 × 10-⁹ m 1-An alpha particle lies on the x-axis, a distance of 1.0 nanometer from a proton (in this set-up, the alpha particle is at the origin while the proton is in the positive direction). Which of the following choices below represents the magnitude of the electric force on the alpha particle? (a) 2.3 × 10-10 N (b) 4.6 × 10-¹0 N (c) 2.3 × 10-19 N (d) 4.6 × 10-19 N eplacing the voltage sou the following inst choices below time != 1.00 37 instantaneous current

30. Suppose ,m) is a common eigenvector of î² and î₂ . Then î²|l,m) = Î₂|l,m) = Î ± |l,m) = = (1,m|L²|1',m) (1,m|L₂|I',m') (1,m|L₂|1',m') = =

I'm still confused about the step 2 part. How would I put this into my calculator? Where do the extra numbers 232.6 come from?

Astronomers believe that the universe is expanding and that stellar objects are moving away from us at a radial velocity V proportional to the distance D from Earth to the object. (a) Write V as a function of D using H as the constant of proportionality. V = (b) The equation in part (a) was first discovered by Edwin Hubble in 1929 and is known as Hubble's law. The constant of proportionality H is known as Hubble's constant. The currently accepted value of Hubble's constant is 70 kilometers per second per megaparsec. (One megaparsec is about 3.086 x 1019 kilometers.) With these units for H, the distance D is measured in megaparsecs, and the velocity V is measured in kilometers per second. The galaxy G2237 + 305 is about 122.7 megaparsecs from Earth. How fast is G2237 + 305 receding from Earth? km/sec (c) One important feature of Hubble's constant is that scientists use it to estimate the age of the universe. The approximate relation is 1012 where y is time in years. Hubble's constant is…
