Answer:

classifying: are made by using the 5 senses.  Good observations are essential in learning the other science process skills.

Examples:

The learner will be blind folded and make observations using the sense of touch.  

The learner will create  observations about a coin using the 5 senses.

The learner will mix primary colors to create more colors.

answer

2. <em>Classifying</em>: making observations is important to notice similarities, differences with the garden vegetables

<em>inferring</em><em>:</em> use your information that u already know

<em>measuring</em>:The learner will find the mass of different liquids that have the same volume

<em>communication</em>:It is important to be able to share your information.  This can be done with graphs, diagrams, maps, and spoken word

Explanation:

can u mark as brainliest pls

The rubber and plastic used in protective clothing do not allow the flow of electric charge
erica [24]

Answer:

True

Explanation:

Insulators are the material that does not allow electricity to pass easily through them. The reason behind using an insulator as a protective layer on an electrical wire or appliances is that they show good resistance to electricity. That prevents us from getting an electrical shock. And rubber and plastics are good examples of the insulator.

Hence our statement is true.

A student made the claim that a 4 gram paintball fired from a paintball gun at 90 m/s could have about the same kinetic energy a
Fiesta28 [93]

Answer:

I do agree with the student. Because imagene you have a tissue and a stick. And you throw them at the same speed , the stick will go farther because it' s heavier but the tissue would just blow around and not go forward because it is not heavy enought.

Explanation:

Hope this is correct have a terrific day.

A timline is necessary :
kolezko [41]

Answer:

A. For every goal

Explanation:

A timeline is necessary for every goal set, be it academic, life, high school, personal, and the like. A timeline is an important part of goal setting. It helps determine what should be done by a certain time to ensure that you will reach your goal. Although some goals can take a long time to reach, a timeline will be your constant reminder of what needs to be done.

When setting a timeline, you also need to take in consideration what you want to achieve. You need to set a realistic timeline as many usually underestimate the obstacles they may face in pursuing their goals.

Particle A of charge 3.06 10-4 C is at the origin, particle B of charge -5.70 10-4 C is at (4.00 m, 0), and particle C of charge
Alex

Answer:

F_net = 26.512 N

Explanation:

Given:

Q_a = 3.06 * 10^(-4 ) C

Q_b = -5.7 * 10^(-4 ) C

Q_c = 1.08 * 10^(-4 ) C

R_ac = 3 m

R_bc = sqrt (3^2 + 4^2) = 5m

k = 8.99 * 10^9

Coulomb's Law:

F_i = k * Q_i * Q_j / R_ij^2

Compute F_ac and F_bc :

F_ac = k * Q_a * Q_c / R^2_ac

F_ac =  8.99 * 10^9* ( 3.06 * 10^(-4 ))* (1.08 * 10^(-4 )) / 3^2

F_ac = 33.01128 N

F_bc = k * Q_b * Q_c / R^2_bc

F_bc =  8.99 * 10^9* ( 5.7 * 10^(-4 ))* (1.08 * 10^(-4 )) / 5^2  

F_bc = - 22.137 N

Angle a is subtended between F_bc and y axis @ C

cos(a) = 3 / 5

sin (a) = 4 / 5

Compute F_net:

F_net = sqrt (F_x ^2 + F_y ^2)

F_x = sum of forces in x direction:

F_x = F_bc*sin(a) = 22.137*(4/5) = 17.71 N

F_y = sum of forces in y direction:

F_y = - F_bc*cos(a) + F_ac = - 22.137*(3/5) + 33.01128 = 19.72908 N

F_net = sqrt (17.71 ^2 + 19.72908 ^2) = 26.5119 N

Answer: F_net = 26.512 N
