Answer:

The US flag has 3 colours, blue, red and white.

Now, first you need to remember that the white is a combination of all the colours, and black is the absense of all colours.

Only red lights:

The red in the flag is transmited, because the filter does not affect that colour.

The blue is absorved, so the blue parts will turn black

The white light is all absorved exept for the red contribution, so the white parts are red now.

Only blue light:

Simillar to before.

The blue parts are not affected.

The red parts are black now.

The white parts are blue now.

Red: The red parts will stay the same
         The blue parts will turn black - there is no red in blue
         The white parts will turn red - there is red in white
Blue: The blue parts will stay the same
         The red parts will turn black - there is no blue in red
         The white parts will turn blue - there is blue in white

A tennis player smashes a ball of mass m horizontally at a vertical wall. The ball rebounds at the same speed v with which it st
Morgarella [4.7K]

Answer:

<em> B.0</em>

Explanation:

Change in momentum: This is defined as the product of mass and change in velocity of a body. or it can be defined as the product of force and time of a body. The fundamental unit of change in momentum is kg.m/s

Change in momentum = M(V-U)......................... Equation 1

where M = mass of the ball, V = final velocity of the ball, U = initial velocity of the ball.

Let: M = m kg and V = U = v m/s

Substituting these values into equation 1

Change in momentum = m(v-v)

Change in momentum = m(0)

Change in momentum = 0 kg.m/s

<em>Therefore the momentum of the ball has not changed.</em>

<em>The right option is B.0</em>

1. James drives 400 km in 5 hours to his grandmothers. What are the units for speed going to be?
Airida [17]

Answer:

See the answer below

Explanation:

1. Speed is calculated as the ratio of distance and time. Hence, Jame's speed can be calculated as:

       400/5 km/hr = 80 km/hr

The unit for the speed would be km/hr. This can also be converted to m/s:

80 km = 80,000 m

1 hr = 3,600 s

80 km/hr = 80,000/3600 m/s = 22.22 m/s

2. Since James drove 400 km in 5 hours, the distance he drove is 400 km.

3. The time it took for James to get there is 5 hours.
