1 km = 1000 m
1 min = 60 s
Entonces
60 km/min * (1000 m/km) * (1/60 min/s) = 1000 m/s

Answer:
(A). The time is 5.47 sec.
(B). The speed of the rock just before it strikes the ground is 39.59 m/s.
Explanation:
Given that,
Initial velocity = 14.0 m/s
Height = 70.0 m
(A). We need to calculate the time
Using second equation of motion
Put the value into the formula
(B). We need to calculate the speed of the rock just before it strikes the ground
Using third equation of motion
Put the value into the formula
Hence, (A). The time is 5.47 sec.
(B). The speed of the rock just before it strikes the ground is 39.59 m/s.
Answer:
A fluid that has properties, such as a large and uniform thermal expansion coefficient, good thermal conductivity, and chemical stability, that make it suitable for use in a thermometer. Thermometric liquids are those that are used in thermometers. Some examples of such liquids are mercury and alcohol.
