Answer:

H= Planck's Constant

Explanation:

Since light is bundled up into photons, Einstein theorized that when a photon falls on the surface of a metal, the entire photon's energy is transferred to the electron.

What is the penetrating power of beta
zlopas [31]
The penetrating power of alpha rays, beta rays, and gamma rays varies greatly. Alpha particles can be blocked by a few pieces of paper. Beta particles pass through paper but are stopped by aluminum foil. Gamma rays are the most difficult to stop and require concrete, lead, or other heavy shielding to block them.

Question 23 (3 points)
Mice21 [21]

Answer:

<h2>The answer is 3.0 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of aluminum = 8.1 g

density = 2.7 g/mL

It's volume is

volume =  \frac{8.1}{2.7}  \\

We have the final answer as

<h3>3.0 mL</h3>

Hope this helps you

You estimate that you sent 135 texts last week but when you get the bill, it was actually 175. Calculate the percent error
FinnZ [79.3K]

Answer: -40

Explanation: Percent error is calculated by subtracting the value you actually recieved from the literature value (175 in your case)  SO your answer should be 135-175=-40.

Hen a wire carrying a current is wound into a series of loops called coils, each turn of the wire produces a magnetic field. The
Lady_Fox [76]

Answer:

<u><em>Hope it helped </em></u>↓

Explanation:

Electromagnets are basically coils of wire which behave like bar magnets with a distinct north and south pole when an electrical current passes through the coil. The static magnetic field produced by each individual coil loop is summed with its neighbor with the combined magnetic field concentrated like the single wire loop we looked at in the last tutorial in the center of the coil. The resultant static magnetic field with a north pole at one end and a south pole at the other is uniform and a lot more stronger in the center of the coil than around the exterior. So a good question could be "Are electromagnets a magnet that respells, or attracts?" Then find away to explain that question/

(you don't have to do this question it is just a example.)
