Answer: 1. B. The number of electrons emitted from the metal per second increases.
2. The maximum speed of the emitted electrons increases.
The stopping potential increases
Explanation:
Photoelectric effect is simply referred to as the emission of electrons that occurs when there's an electromagnetic radiation. An example of such electromagnetic radiation is when material is being hit by light.
Assuming that the light incident on the metal surface causes electrons to be ejected from the metal, the number of electrons emitted from the metal per second increases if the intensity of the incident light is increased.
Also, if the initial light incident on the metal surface causes electrons to be ejected from the metal, the maximum speed of the emitted electrons increases and the stopping potential increases.

The only one way that heat can move is: From
higher temperature
to lower temperature, never the other way.
Examples:
-- When you put an ice cube into a glass of warm soda, heat never moves
out
of the ice cube into the soda, making the soda warmer.</span>
-- When you mix cold water with warm water, heat never moves out of the
cold water into the warm water, causing ice to appear and the warm water
to get warmer.
-- When you blow your breath across a spoonful of hot soup, the soup
never draws heat out of your breath, chilling your breath and boiling the
soup on the spoon.
-- When you step into a warm steaming bubble bath, heat never moves
from your body into the hot bath, causing your tootsies to shiver and the
bath to get even hotter.
“It states that parts of the Earth's crust slowly drift atop a liquid core. The fossil record supports and gives credence to the theories of continental drift and plate tectonics. ... Continental Coastlines appearing to fit together,Fossil Distrubution, Distinctive Rock Strata, and Coal Distrubution.”

Answer:
liquid?
Explanation:
liquid: A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving. It takes the shape of its container but maintains constant volume.
