Answer:
<h2>
14.66secs</h2>
Explanation:
Given the formula for calculating the depth in metres expressed as
depth in meters = ½ (1500 m/sec × Echo travel time in seconds)
Given depth of the challenger = 10, 994 meters, we will substitute this given value into the formula given to calculate the time take for the echo to travel.
10, 994 = depth in meters = ½ * 1500 m/sec × Echo travel time in seconds
10,994 = 750 * Echo travel time in seconds
Dividing both sides by 750;
Echo travel time in seconds = 10,994 /750
Echo travel time in seconds ≈ 14.66secs (to two decimal places)
Therefore, it would take an echo sounder’s ping 14.66secs to make the trip from a ship to the Challenger Deep and back
Air pollution!! Can I have brainlyist:))
The circumference of a circle is (2π · the circle's radius).
The length of a semi-circle is (1π · the circle's radius) =
(π · 14.8) = 46.5 (rounded)
(The unit is the same as whatever the unit of the 14.8 is.)
Hi!
The correct option would be A) Mendel’s genetics states laws that are now part of the theory of biological evolution.
When Darwin proposed the idea of biological evolution, which revolved around the concept that favorable genes are naturally selected into a species to ensure survival, his theory was criticized as during that time there was the idea that individual traits of two parents would present themselves as a blend in the offspring.
Gregor Mendel's theory of inheritance supported Darwin's idea as it dealt with the transmission of traits in generations through entities called genes, which were present in pairs for a particular trait.
Hope this helps!
