A student kicks a soccer ball three times. Another student records the distance, the amount of time the ball travels, and the average speed in the table shown below. How many seconds did it take for the ball to travel 30 m during Kick 3?



F. 0.5 s

G. 1.0 s

H. 1.5 s

J. 2.0 s​

Answers

Answer:

2/j

Explanation:

formula: average speed= total distance/total time

                15=30/total time

                  30/15= 2

Hope this helped and good luck!!!

It would take 1 second for the ball to travel 30 m during Kick 3

Speed

Speed is the ratio of total distance travelled to total time taken. It is measured in meters per second. The formula for speed is given by the equation:

Speed = distance / time

From the question, average speed = 30 m/s, hence:

Average speed = distance / time

30 = 30 / time

time = 1 second

It would take 1 second for the ball to travel 30 m during Kick 3.

A) genetically varied.
B)

slightly similar to the parent.
D)
genetically very different from the parent

Answers

Answer:

There is no illustration, but the question can be answered based on general understanding of reproduction. The answer is:

B) genetically identical to the parent.

Explanation:

Reproduction, which is the process by which organisms produce their offsprings, can be done in two major ways namely: sexually and asexually. The asexual reproduction involves only one parent that undergoes division to form two daughter cells.

Since there is no exchange of genetic material between two parties as it involves only a single organism, the offsprings will be GENETICALLY IDENTICAL to the parent cell. This is the case of Hydra in this question that underwent asexual reproduction. All of the offsprings of this mode of reproduction will be GENETICALLY IDENTICAL i.e. have the same genetic composition as their parent.

What are the FIVE ways an object's motion can change?

Answers

Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.

Explanation: please can I get brainliest

Motion is defined as the phenomena where an object moves from one point to another. Usually, a force has to act on the object for it to be in a state of motion.

Mathematically, motion has to do with:

AccelerationDisplacementDistanceVelocitySpeedTime.

With this in mind, the five ways an object's motion can change include:

When the speed acting on the object changesWhen the force acting on the object changesWhen the acceleration changesWhen the velocity acting on the object changesWhen there is a greater displacement acting on the object.

Explain why the energy that is stored in the chemical bonds of a

Answers

Answer:

Because the atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.

Explanation:

Thats why the energy that is stored in the chemical bond of a molecule is not destroyed when that molecule is broken down to smaller molecules

The atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.

What is Chemical bond?

The energy that is stored in the chemical bond of a molecule is not destroyed when that molecule is broken down to smaller molecules.

When atoms are attracted to each other and join together to form a molecule, we call the connection between each atom a chemical bond. The bond “holds together” the atoms in the molecule, ion, or crystal.

Chemical bonding is the attraction between two or more atoms that allows them to be able to form a stable chemical compound. The specific nature of a chemical bond can vary, but the most commonly known are covalent and ionic bonds.

Therefore, The atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.

Answers

MALE - XY

FEMALE 1 - XX

FEMALE 2- XX

The correct symbols that describe the gender of a male and 2 female kittens would be XX, XX, and XY

Gender chromosomes

Just like humans, male cats are generally known to be heterogametic while their females are homogametic when it comes to gender chromosomes.

The gender chromosome in male cats is XY while in the female it is XX.

Thus, a little of 3 kittens consisting of 2 females and 1 male will have the gender chromosome symbol of XX, XX, and XY.
