<h2>Comparing kinetic energy of Boat A and B -Option 4 </h2>

Compared to the kinetic energy of Boat B, the kinetic energy of Boat A is nine times as much. Kinetic energy ( K.E ) is the energy which is possessed due to movement or motion. Its formula is 1 / 2 mv 2, there is square of velocity in terms of kinetic energy.

If the velocity of boat A is three times greater than that of boat B and the condition is both boats have the same mass so by putting values. Mass is constant and the square of velocity is ( 3 ) 2 = 9 therefore, 1 / 2 m ( 3v ) 2 = 1 / 2 m 9 v 2.

If we write it as 9 ( 1 / 2 m v 2 ) it means that kinetic energy of boat A is nine time as much.

Question 2<br> The solid portion of Earth is made up of oxygen and this element is _____.
jarptica [38.1K]

Explanation:

Tarbuck, Earth's crust is made up of several elements: oxygen, 46.6 percent by weight; silicon, 27.7 percent; aluminum, 8.1 percent; iron, 5 percent; calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent

About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which all together constitute the hydrosphere.

...

Earth.

Almost 99% of the minerals making up the Earth's crust are made up of just eight elements. Most of these elements are found combined with other elements as compounds.

Carlo is wondering what causes plants to grow at different rates. Carlo's hypothesis is "Plants will grow more when the day is l
Sphinxa [80]

Options for the question have not been given. They are as follows:

type of soil

type of plants

exposure to sunlight

method for measuring the growth

Answer:

exposure to sunlight

Explanation:

A scientific experiment has an experimental group and a control group. Control group is included to omit any error in results due to the factors other than the variable factor. Experimental group is the one exposed to different levels of the variable factor.

Here, Carlo wants to determine the the effect of day length on plants' growth. The test variable here is thus the duration of sunlight. In experimental group, this duration will be changed to determine its effect. In control group it will be kept constant so that results from other factors can be excluded from the observed experimental result.

What is the flow of molecules in passive transport?
Vilka [71]

Answer:

The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration.

Explanation:

hope this helps :D
