Answer:
a. 3 and 56, respectively.
Step-by-step explanation:
The computation of the degrees of freedom for the numerator and denominator for the critical value of F is given below:
k = 4
n = 15
Total degree of freedom is
= nk - 1
= 59
For numerator, it is
= k -1
= 4 - 1
= 3
and for denominator it is
= T - (k -1 )
= 59 - 3
= 56

Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle
Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.
The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
Answer: 1.86 repeating
Step-by-step explanation:
Answer:
117.3 feet per second.
Step-by-step explanation:
Velocity is the speed of an object in a definite direction. In mechanics, velocity is a vector quantity. It requires magnitude and direction to make any sense. Velocities are expressed per unit time.
The SI unit of time is the second.
Now, suppose we need the velocity in feet per second. A simple calculation will help:
feet per second = miles per hour × 1.466667 [ in other words, one mile per hour equals 1.466667 feet per second]
For a space capsule moving at 80 miles per hour, the velocity is given by
= 80 × 1.466667
= 117. 3 ft/s [feet per second]
