Answer:
Mercury's natural state is where the atoms are close to each other but are still free to pass by each other. In which state(s) could mercury naturally exist?
Liquid is the answer
Explanation:
Explanation:
because the acceleration is negative, this indicates a deceleration (or slowing down) . Hence we can say that:
The car is decelerating (slowing down), i.e its velocity is decreasing, at a constant rate of 5m/s².
Answer:
Explanation:
Often times, the property of air masses is a function of where they originate from especially with respect to latitude.
An air mass is certain amount of air with some unique set of temperature and vapor component.
- Air masses differs from places to places based on where they originate.
- Continental air masses are usually dry and cold because there is little to no water on a land mass.
- Air masses that originates from the surface of the ocean are predominantly moist.
- In polar regions, the air mass is cold.
- Around the tropics, they are usually warm due to insolation here.
Answer: a. 53cm b. Diverging c. 0.02dioptres
Explanation:
Since the person in question cannot see far object clearly, it shows that the individual is suffering from myopia (short sightedness).
If the object distance (u) is 53cm. for the person to be able to see far way, it means the image must be at infinity. This shows image distance v is infinity. Using the lens formula
1/f = 1/u+1/v
1/f = 1/53 + 1/Infinity
1/f = 1/53 + 0
f=53cm
b) The lens used is concave lens (diverging lens) to diverge all rays outwards
c) Power of a lens P will be 1/53.
P = 0.02dioptres
