RSB [31]

Answer:

Between 100 and 120 million years old

Explanation:

The principle of superposition refers to one of the geological principles used in the determining the relative depositional history or sequence of rock stratas in geologic stratigraphic study. The superposition principle explains that rocks deposited in stratas with the oldest rock layer being at the base and the youngest at the topmost layer. Hence using this principle, we can conclude that ; Rock layer M lies in between layer T and R ; thus M is younger than T and older than R. Therefore, the age of M will be between the range of age T and R.

An object moves with a positive acceleration. Could the object be moving with increasing speed, decreasing speed or constant spe

Masja [62]

Answer:

Increasing speed.

Explanation:

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

$Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}$

In this scenario, an object moves with a positive acceleration. Thus, the object is moving with an increasing speed and as such it has acceleration in the same direction as its velocity with respect to time.
