Answer:
The correct option is;
a) Mike, he is within his target heart rate zone
Explanation:
The Target Heart Rate Zone (THRZ) is the range of the percentage of a person's maximal heart beat rate (MHR) targeted to be achieved during exercising. It is a very good way to gauge the comparative intensity of a person's exercise
Whereby, Joe's heart beat rate is below his THRZ and Mikes heart beat rate is within his THRZ, Mike is working harder.
Hence the correct option is (a) Mike, he is within his target heart rate zone.
<span>a tsunami travels at a speed that is related to the water depth - hence, as the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami's speed diminishes as it travels into shallower water, its height grows.</span>
<span>Acceleration is a change in motion ... slowing down, speeding up,
or changing direction even if speed doesn't change</span>.
The number of outcomes in the compliment of the event are 0.54
<h3>Concept and calculation</h3>
No of strawberry plants in the field = 259259
No of plants that are ready for picking = 142142
so no of outcomes = 142142/ 259259 = 0.54 outcomes
<h3>Understanding of probability</h3>
The area of mathematics that deals with probability is called probability theory.
Probability is a concept that can be interpreted in a variety of ways, but probability theory tackles the idea in a rigorous mathematical way by expressing it through a series of axioms.
Typically, these axioms formalize probability in terms of a probability space, which links a collection of outcomes known as the sample space to a measure taking values between 0 and 1. An event is any defined subset of the sample space.

As we know that when object is connected to spring then the motion is to and from about the mean position
Then the acceleration is given as
here we know that
= angular frequency
now if the displacement from mean position is zero then we will have x =0
and hence the acceleration must be zero
so we will say that acceleration and displacement both are zero when object is at equilibrium position
So correct answer will be
<u>C. at the equilibrium position </u>
