Answer and Explanation:

The factors that affects the quality of an LCD monitor or screen are:

1. Resolution:

It refers to the number of pixels (vertical and horizontal) that constitutes the display of the LCD matrix. The more the number of pixels the greater will be its resolution and a clearer image is formed.

2. Brightness:

To obtain a brighter image the measurement in $Cd/m^{2}$ referred as nits should be greater.

3. Contrast Ratio:

high contrast ratio ensure the representation of colors in a way better manner.

4. Dot Pitch:

A smaller dot pitch provides the image of better quality on the LCD screen.

5.Response Time:

To avoid the blur effect, the recommended response time is 12 ms or lesser.

6. Pixel Pitch:

To obtain a sharper image on the monitor, the pixel pitch must be smaller.

m₁v₁ + m₂v₂ = (m₁ + m₂)vmomentum is conserved.the left-hand side of the equation represents the momentum in the system before the collision.the right-hand side represents the momentum in the system after the collisionm₁ and v₁ represents the mass and the velocity of the physics blockm₂ and v₂ represents the mass and velocity of the ball of puttyv represents the final velocity of the combined mass.the question states the two masses stick together. they combined mass has its own velocity with the body mass the sum of the two objects' massestheir combined momentum is (m₁ + m₂)vto find the magitude of (m₁ + m₂)v, we need to add the vectors on the left-hand side of the equation: m₁v₁ + m₂v₂.note the diagram. i have positioned the vectors in accordance with their directions.the magnitude of the resultant can be calculated using the pythagorean theorem since this is a right triangle situation (north and west are perpendicular)|(m₁ + m₂)v| = √[ (m₁v₁)² + (m₂v₂)² ]|(m₁ + m₂)v| = √[ (1.5kg·8.0m/s)² + (0.40kg·20m/s)² ]|(m₁ + m₂)v| = 14.4 kg m/sfor two significant figures (assuming that 20m/s is two), this rounds to 14 kg m/s
