Answer:
<em>b. There will be more electrons emitted.</em>
Explanation:
In photoelectric emission, the energy of the emitted electron is dependent on the frequency of the wave incident on the plate; but not the intensity. The rate of electron emission per unit time however depends on the intensity of the incident light. So increasing the intensity of the light at constant frequency will only affect the number of electrons emitted per unit time.
Answer:
counterclockwise and inward
Explanation:
Extratropical cyclones or mid-latitude cyclones are the low-pressure areas, along with anticyclones of the high-pressure areas that drive weather over much of the Earth.
<u>Due to the Coriolis effect, the flow of the wind around the extratropical cyclone is counterclockwise in direction in the northern hemisphere, and clockwise in direction in the southern hemisphere.</u>
<u>It forms a comma shape which drives the forces inward the center.</u>
Answer:
A mercury barometer is an instrument used to measure atmospheric pressure in a certain location and has a vertical glass tube closed at the top sitting in an open mercury-filled basin at the bottom. Mercury in the tube adjusts until the weight of it balances the atmospheric force exerted on the reservoir.
Explanation:
Answer: The gravitational acceleration on planet X is 5 N/kg
On Earth (with the gravitational accelartion g_E) the mass of 2kg will correspond to
On planet X we are told the same measure is only 10N. Since there is a proportional relationship between g and F, we can calculate g_X:
