Answer:
Explanation:
Standard International (SI) units of measurement is the acceptable global units of measure for physical quantities. they are majorly fundamental units.
Thus,
(a) The mass of a sport car is measured in kilograms (kg).
(b) The distance from your home to your school is measured in meters (m).
(c) The mass of an elephant is measured in kilograms (kg).
(d) The diameter of a large pizza is measure in meters (m).
(e) A semester at your school is measured in weeks.
(f) The time for light to travel from the sun to the earth is expressed in seconds (s).
(g) The time it takes to fly from New York to California is in seconds (s).
(h) Your mass is measured in kilograms (kg).
(i) The length of the Prime Meridian is expressed in meters (m).
(j) Your height is expressed in meters (m).
Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second.

Answer:
The velocity of the bus at B is 
Explanation:
Let's take position B as base point .
From the diagram height between point B and A ia mathematically evaluated as
From the question we are told that
The velocity at location A is 
According the law of conservation of energy
Where 
is the potential energy at A which is mathematically represented as
is the kinetic energy energy at A which is mathematically represented as
is the kinetic energy at A which is mathematically represented as
Where 
is the velocity at location B
So
Making the subject of the formula
Substituting values
The melting of polar ice caps is an example of the interaction between the atmosphere and cryosphere.
Answer: A
Atmosphere is a layer of gases surrounding the earth, while cryosphere are all parts of the Earth where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground.
