The answer is The coastline experiences tidal bulge twice a day. This occurs due to the rotation of the earth. When the sun is either on the same side as the moon or opposite side of the moon relative to the earth (which happens twice a day), then the coastline will experience high tide on these two occasions. Tides are caused by gravitational effect on water masses on the earth that cause them to bulge towards the direction of the two celestial bodies.
Answer:
3.0 V
Explanation:
The voltage across the bulb is the voltage across the batteries, since the batteries are the only source of power for the bulb. So the voltage across the batteries is 3.0 V.
Answer:
Their number should increase
Explanation:
The photoelectric effect is a phenomenon that causes the ejection of electrons from that metal as light shined onto a metal surface. Only certain frequencies of light can cause the ejection of electrons. However, if the frequency of the incident light is too low then no electrons were ejected even if the intensity of the light was very high. If the frequency of the light was higher then electrons were able to be ejected from the metal surface even if the intensity of the light was very low.
According to the accepted wave theory, light of any frequency will cause electrons to be emitted. Kinetic energy emitted by the electrons depends upon the intensity of light.
According to the accepted wave theory, number of electrons being ejected by the metal should increase
Answer:
65 miles
Explanation:
The distance travelled till 150 miles is
260 - 150 = 90
But as he walks back although his distance increase his displacement from initial point decrease.
Distance moved from 150 mile post to 175 mile post is
175 - 150 = 25
As he walks backwards in second time in consideration with first time to calculate the displacement we need to substract 90 from 25,
So displacement is 65 miles
The correct answer is - non-explosive one.
The type of eruption in the volcano depends on the composition of the magma.
If the magma has higher content of silica and water, the magma will be more viscous, which in turn will trap the gases, and that will result in explosive eruption.
If the magma is low on silica and water content, the magma would be less viscous, which in turn will not be trapping the gases, and the result will be non-explosive eruption, where there's lava flows coming down the volcano.
