The labyrinthodont lived in Antarctica. It is a reptile and extinct amphibians subclass, known as the very first vertebrates to walk on land. In the mountains of Antarctica in the Transantarctic during the austral summer, in 1969-1970 bones of Lower Triassic vertebrates were excavated. It includes the labyrinthodont amphibian.
Power = (voltage) x (current)
100w = 220v x current
Current = 100w / 220v = <u>0.455 Ampere</u> (rounded)
<u>Absorb:</u>
Shine a light with known intensity into the object.
Measure the intensity of the light that comes out.
Any light that goes in but doesn't come out the other side
was absorbed by the object.
(Note: You also need to be aware of any light that bounces back from
the first side without entering the object. That light is <em><u>reflected</u></em> from it,
and can't be expected to show up at the other side.)
<u>Transmit:</u>
Any light that goes in and DOES come out the other side
was transmitted by the object.
Answer:
50%
Explanation:
Humidity is the amount water vapor present in the atmosphere.
Relative humidity is defined as the ratio of partial water vapor present in air to the actual water vapor at a particular temperature. It is expressed in percentage and the higher the percentage RH, the more the saturated water vapor present in the atmosphere and vice versa.
It is expressed mathematically as shown;
RH = actual water vapor in air/saturated water vapor × 100%
If the actual water vapor in the air was 4 grams per cubic meter and the air's capacity to hold water vapor was 8 grams per cubic meter
Actual water vapor = 4g/cm³
Air's water capacity (saturated water vapor) = 8g/cm³
RH = 4/8×100
RH = 50%
