a. he is accelerating

b. he is covering a greater distance in each consecutive second.

c. he is moving with a constant speed (on average).

Answers

Answer: c

Explanation: for #5 it can still be moving, just at a constant speed; therefore, it will be c.

If an object has an acceleration of 0 m/s2, then one can be sure that the object is not changing velocity.

If car A passes car B, then car A must be moving faster than car B, but not necessarily accelerating.

The not consistent with a car that is accelerating is a car is moving at a high speed.

A fullback is running down the football field in a straight line. He starts at the 0-yard line at 0 seconds. At 1 second, he is on the 10-yard line; at 2 seconds, he is on the 20-yard line; at 3 seconds, he is on the 30-yard line; and at 4 seconds, he is on the 40-yard line. This is evidence that he is moving with a constant speed (on average).

What is Acceleration?Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). Speed is the distance covered in a unit of time while acceleration is the rate of change in speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity while acceleration is a vector quantity.

But taxonomists, as organized as they maybe, have no idea how many species Earth has. Nor can they even provide aneducated guess. Although reporting over 16,000 new species every year,taxonomists still cannot predict how many more are undiscovered.In total, taxonomists have categorized and listed 1.2 million species on Earth. At thispoint, you would think scientists should be able to use the information they havegathered to make good predictions about how many species an ecosystem cansupport. This would help them make better predictions about how many species areleft to identify. So far, however, the guesses seem to vary so greatly that it seemsthere is no good theory for making a prediction.One of the main problems is that most of the places that seem to have a lot ofdiverse species are in places that are hard to get to. One such place is the ocean,where scientists believe some 80 percent of Earth's creatures are hiding at depthstoo deep for us to study. In addition, many of the planet's most diverse areas are inremote places with few taxonomists.Despite all the unknowns, scientists have agreed that there are between five and 15million species left to discover on Earth. This is a huge range, but whether it's five or15, taxonomists clearly still have a lot of work to do. And who knows, there may yetbe a dragon or a Loch Ness monster left to discover.Which word from the second paragraph explains what taxonomists do?
