Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. The air above the sea becomes less dense (i.e. warmer) and rises. The cooler air from the land moves in to take its place. Sea breeze: Sea breeze blows during the day and the land heats up faster than the sea
Answer:
2.94 × 10²⁰ N/C
Explanation:
Given that:
The nucleus of "Lead-208 has 82 protons,
with a radius (r) 6.34×10-15 m, &
each electric charge has a value of 1.60218 × 10^-19 C
∴ The formula for calculating an electrical field at the surface of the nucleus is:
Substituting our values into the equation above, we have;
E = 
E = 2.93870499×10²⁰ N/C
E ≅ 2.94 × 10²⁰ N/C
Answer:
A great example is the peppered moths evolution. Since the Industrial Revolution the birch trees started to turn black from the soot. This casued all the white moths to be eaten from birds. The ones that were left to mate were black moths which favored the black gene. So overtime black moths became more common. They were naturaly selected based on color to survived and pass down their black colored genes.
Explanation:
Compounds microscope is an optical instrument for forming magnifying images of small objects having an objective Len with a very short focal length. While electron microscope is a high power of microscope uses beam of electron focused by magnetic lenses instead of rays of light.
A. Pre-eclampsia
Pre-eclampsia also
known as pregnancy induced hypersion or toxemia. It is a pathological condition
in pregnancy that is characterized by hypertension, edema and proteinuria.
However, pre-eclampsia is a symptom that is associated with late pregnancy that
encompasses both convulsive and non-convulsive stage.
