Ted William drops a ball from 14.5 meter to a desk that is 1.9 meters tall. What is the final speed of the ball right before it hits the desk.

Answers

Answer:

15.7m/s

Explanation:

To solve this problem, we use the right motion equation.

Here, we have been given the height through which the ball drops;

Height of drop = 14.5m - 1.9m = 12.6m

The right motion equation is;

V² = U² + 2gh

V is the final velocity

U is the initial velocity = 0

g is the acceleration due to gravity = 9.8m/s²

h is the height

Now insert the parameters and solve;

V² = 0² + 2 x 9.8 x 12.6

V² = 246.96

V = √246.96 = 15.7m/s

Flatworms can be cut in half, creating two new individuals, by _____.binary fission
multiple fission
fragmentation
budding

Answers

Flatworms can be cut in halfcreating two individuals by binary fission. Binary fission is a type ofasexual reproduction in which the offspring has the same features andcharacteristics of the parent. During binary fission, the DNA replicates intotwo and goes at the end of each membrane. And then the cell membrane divides intotwo daughter cells. Then cytokinesis follow.

Answer:

If you think about you're cutting and Flatworm in half. Flatworms don't naturally divide/create new individuals by binary fission. So, the answer would be c) fragmentation; based on the fact that you are the one cutting the Flatworm, not the other way around.

The picture above shows 3 sets of balloons, all with a particular charge. Which of the picture(s) is true? Explain. Then explain why the other 2 pictures are incorrect. Make sure to explain all 3 sets.

Answers

Among all of the others Picture 3 is correct.

We know, Like charges repel each other whereas unlike charges attract each other, In picture 3 they are like charges (both are positive) so, we can repulsion hence, picture is correct!

In picture 1, they are unlike charges, & showing repulsion which is wrong, same In picture 2, they are like charges & showing attraction so they are wrong as well

Hope this helps!

C is correct because they would repel each other A is wrong be they wouldn't repel And B is wrong because they shouldn't be repelling each other
