Explanation:

What is the purpose of the scientific method?

<em><u>ans/</u></em>

the goal of any scientific method is to solve a problem or to better understand an observed event.

b.

i. What does the law of conservation of energy say?

<em><u>ans/</u></em>

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.

ii. List two different kinds of energy.

<em><u>ans/</u></em>

Potential energy.

Kinetic energy.

iii. What does the law say about changes energy can undergo?

<em><u>ans/</u></em>

The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.

Answer:

ii. Purpose of scientific method

=The Scientific Method helps you put together experiments, use data to find conclusions and interpret them. In short, the Scientific Method is a step-by-step process: First, observe. Use your senses and take notes about the situation

tiny-mole [99]

Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth

Newton's Second law of motion states that "<em>the </em><em>acceleration</em><em> of an object depends upon </em><em>two</em><em> </em><em>variables</em><em> – the net force acting on the object and the mass of the object.</em>"

In our case the mass of the book and the force of gravity

What is the charge associated with each side of the HCl molecule?
Alexandra [31]

HCl is a polar molecule with the hydrogen part being partial positive while the chlorine end being partial negative. This is because hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. This means that chlorine attracted most of the electron cloud of molecule hence is the negative dipole, The dipole moment of HCl is 1.08 D (debyes). A Debye is equal to 3.34 x 10-30 coulomb-meters (C-m). The charge of each molecule is o.176+ for H and 0.176- for the Cl

A blood sample of 4.01 milliliters is collected from a patient to be analyzed for a platelet count. Human blood should have arou
Harlamova29_29 [7]

Given :

Human blood should have around 1.04 kg/L platelets.

A blood sample of 4.01 milliliters is collected from a patient to be analyzed for a platelet count.

To Find :

The expected mass in grams of platelets in the blood sample.

Solution :

1 L of human blood contains 1.04 kg of platelets.

So, amount of platelets is 1 ml blood is :

=\dfrac{1.04}{1000}\ kg\\\\= \dfrac{1.04\times 1000}{1000}\ gram\\\\= 1.04 \ gram

Mass of platelets in 4.01 ml blood is :

m = 1.04\times 4.01\ gram\\\\m = 4.1704\ gram

Hence, this is the required solution.

Which is the average kinetic energy of the individual particles of a substance?
zhannawk [14.2K]

Answer: Temperature

Explanation: Temperature is a measure of average kinetic energy of particles in an object. The hotter the substance, higher is the average kinetic energy of its constituent particles. When we heat a substance, the particles that constitute the substance gain some energy and begin to move faster.
