Answer:
Malleability
Explanation:
The ability to roll aluminum foil in a ball is the property of metal called malleability.
- Metallic bonds in metals makes it possible for them to take different shape without losing internal cohesion.
- Metals are malleable and they posses a wide range of physical properties.
- A malleable metal can be beaten into sheets and molded into many shapes.
City 4 because it is closer to the equator

Answer: The ejection rate will increase.</h2>
The photoelectric effect is a phenomenon that consists of the emission of electrons by certain metals when a beam of light impacts on its surface.
For this phenomenon to occur, certain conditions must be met, such as when the photon collides with the electron, in order to "pull it" from the metal, the photon must have a minimum energy equal to the ionization energy of the atom, so that the electron can leave the influence of the nucleus.
This is achieved with the adequate intensity of the incident radiation, which is related to the number of photons that impact the metal.
This means:
<h2>The greater the intensity, the greater the number of photons, hence the greater number of electrons emitted.</h2>
<span>First lets determine the equation. Well at the top of the circle both the normal force and the weight are in the same direction. So we have Fnet=N+mg. Since this is a circular path the Fnet is also = to (mv^2)/r.
We convert the situation where the rock is no longer in contact with the bottom to terms relevant to the equation. So, what is a requirement for normal force? The object must be in contact with the surface, meaning it can't be in free fall. Realizing this means that the instant when the object does not touch the bucket is where the normal force = 0.
Now we have N+mg=(mv^2)/r where N=0 is the case we are interested in. This leaves 0+mg=(mv^2)/r
Solve for v:
v=(gr)^(1/2) or v=3.28m/s
