Answer:

C. Both of A and C

Explanation:

Primary colors are colors that can be combined with one another to form other colors called secondary colors.

Light can be defined as a phenomenon that causes the sensation of vision. The primary colors with regards to light are: red, green and blue. Light is a form of an additive system where there is an addition of two or more primary colored lights to form other colors.

Paints are subtractive systems that produce color due to absorption and reflection of colors. A green paint appears green because it has absorbed other colors and reflects only green. Its primary colors are blue, yellow and green.

Therefore, paints reflect light and take out light from what light is shined onto them.

Answer:

the correct answer is A

Explanation:

In my opinion, the colors in both visual sources are different than in a painting, the color is the wave that is refracted when perceiving it with our human eye (this means that a painting of red color, absorbs all the waves of the color ranges except the color red and that refracted wave is captured by our eye and we visualize it that way) on the other hand, on the television screen or other screens the colors have the same system that we explain with the paintings but they also have more luminosity or greater value, intensity since they emit or emit light and greater brightness.

what is the mass of a cannon ball if a force 2500 N gives the cannon ball an acceleration of 200 m/s squared?
nignag [31]

Using Newton's second law of motion:

F=ma ;  [ F = force (N: kgm/s^2);m= mass (kg); a = acceleration (m/s^2)


Given:                      Find:                   Formula:                  Solve for m:

F: 2500N                 mass:?                F=ma Eq.1              m=F/a  Eq. 2

a= 200m/s^2  


Solution:

Using Eq.2

m= (2500 kgm/s^2)/ (200m/s^2) = 12.5 kg

What do electric forces between charges depend on
denis23 [38]

Answer:

On the magnitude of the charges, on their separation and on the sign of the charges

Explanation:

The magnitude of the electric force between two charges is given by

F=k\frac{q_1 q_2}{r^2}

where

k is the Coulomb's constant

q1, q2 are the magnitudes of the two charges

r is the separation between the charges

From the formula, we see that the magnitude of the force depends on the following factors:

- magnitude of the two charges

- separation between the charges

Moreover, the direction of the force depends on the sign of the two charges. In fact:

- if the two charges have same sign, the force is repulsive

- if the two charges have opposite signs, the force is attractive

The 1350-kg car has a velocity of 24 km/h up the 8-percent grade when the driver applies more power for 18 s to bring the car up
Brrunno [24]

Answer:

Explanation:

We shall apply concept of impulse to solve the problem  .

Impulse = force x time

impulse = change in momentum

force x time = change in momentum

initial speed u = 24 km/h = 6.67 m /s

final speed v = 65 km/h = 18.05 m /s

change in momentum = m v - mu

= m ( v-u )

= 1350 ( 18.05 - 6.67 )

= 15363 kg m/s

F x 18 = 15363

F = 853.5 N .
