Answer : The forces were unequal, then they became equal.

Explanation : According to the attached complete question;

In the first part, where the velocity keeps on decreasing uniformly. The cart is observed to decelerate (here the acceleration is less than 0).  

According to the formula of Force;

F = ma. (where F - Force; m - mass and a -  acceleration)

when it was the case where a ≠ 0, there is a non-zero resultant force acting on the cart.  

Therefore, the forces were unequal in the first part.  

And during the second part, the velocity was observed to be constant, and so the acceleration is  equal to 0.  

Now, using the force formula;

F = ma.

As a = 0, the resultant force acting on the cart will also be 0.

Therefore, the forces are equal in the second part.

Answer:

The forces were unequal, then became equal.

Explanation:

The most likely choice is that the forces were unequal, then became equal. As depicted by the slope in the graph, one of the forces was stronger than the other and caused the cart to slow down. Eventually the two forces evened out and the cart remained at a steady velocity.

Check Your Understanding<br> Question: What is an adaptation?
AleksandrR [38]

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.

Answer:

1) you're going to have to flip the coins (or fake numbers) for the experimental trials.

2) for the theoretical, there is 1/2 chance for heads or tails with each toss, so you'd expect that out of 10 tosses, 5 heads, 5 tails. out of 100 tosses- 50 heads, 50 tails.

When tossing 2 coins- 1/2×1/2 = 1/4 (25%) chance that 2 heads, 2 tails, or 1 heads & 1 tails. Deviation value comes from after you done your flipping and recorded your data. So if on 100 flips you actually got 50 and 50 (rarely us that exact ;), the deviation from the expected of 50/50 would be 0.00. If however you flipped 100 heads or 100 tails (impossible), then the deviation value would be 1.00.

|(100-50)| ÷ 50 = 50÷50 = 1.00

So usually you may have data like: 47/53 or something a little off than 50/50, making deviation |(47-50)| ÷ 50 = 3÷50 = 0.06.

Now the number of flips is important for the outcome! So if a coin toss if 10 times had 4 heads, 6 tails, the deviation value would be:

|(4-5)| ÷ 5 = 1÷5 = 0.20

So increasing the # flips DECREASES the deviation value!!

Whether it's from 10 to 100, or from 100 to 200. Look at my example of how the 10-flip deviation of 0.20 decreased to 0.06 with 100-flip
