Answer:
they are related because..
Explanation:
Physical properties can be observed or measured without changing the composition of matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others
Answer:
The coin has a diameter of 2.67 cm
Explanation:
First, we need to find the volume of each coin by dividing the total volume of silver by the number of coins. We have also to do a conversion of units in terms of centimeters as follows:
Then, we define the coin as a tiny cilinder to determine its diameter. In that order we use the cilinder's volumen equation as follows:
Finally, we know that the diameter is twice the radius, therefore the diameter of each coin is 2.67 cm.
Answer:
<h3>The answer is 180 m</h3>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
distance = velocity × time
From the question we have
distance = 1.5 × 120
We have the final answer as
<h3>180 m</h3>

The patterns that can be looked for when studying science topic include the use of data or carrying out an experiment.
<h3>How to illustrate the information?</h3>
It should be noted that patterns are regular and intelligible forms or sequences that can be found in nature. Based on the information, scientific questions may be generated when scientists want to observe a pattern of events.
It should be noted that when scientists want to observe a pattern of events or
when something does not match an established pattern, scientists can use patterns to classify objects or phenomena into groups.
Therefore, the patterns that can be looked for when studying science topic include the use of data or carrying out an experiment.

The magnitude and sign of the charge are 0.8 MC and negative respectively.
To find the answer, we need to know about the electric potential of a point charge.
<h3>What's the mathematical expression of the electric potential of a point charge?</h3>
- Mathematically, the electric potential at a distance 'r' from a point charge 'q' is given as (Kq)/r.
- K is the electrical constant with value 9×10^(-9) in vaccum.
<h3>What will be the magnitude and sign of a charge, if potential is -3.50V at 2mm?</h3>
From the expression of electric potential, charge is
q= (potential ×r)/K
= (-3.5×0.002)/ (9×10^(-9))
= -0.8 mega coulomb.
Thus, we can conclude that the magnitude and sign of the charge are 0.8 MC and negative respectively.
