Answer:

When photons - rays of light - coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image.... If a smooth surface absorbs the photons, they can't bounce back and there will be no reflection.

Can electromagnetic waves travel in a vacuum? Yes Or No

Sonja [21]

Answer:

Yes

Explanation:

Yes because Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Can someone help? Thanks.

The average speed of Frank's car is 2 m/s and the average speed of Noah's car is 1.8 m/s.

Explanation:

Average speed is the measure of total distance covered at different time period. Since, the formula used for calculating the average speed is the ratio of total distance covered by each car to the time taken to cover that distance.

As there is only one set of data i.e., distance and time, the average speed will be equal to the speed of the car.

So in this case, the total distance covered by franks car is 300 cm = 3 m in 1.5 s. Then, the average speed will be

$Avg. S_{frank} = \frac{Total\ distance\ rolled\ by\ his\ car}{Time\ taken}$

$Avg.S_{frank} =\frac{300 \times 10^{-2} }{1.5}=2\ m/s$

Similarly, the average speed of Noahs car which rolled a distance of 360 cm = 3.6 m in time 2 s, will be

$Avg.S_{Noah} =\frac{360 \times 10^{-2} }{2}=1.8\ m/s$

Thus, the average speed of Frank's car is 2 m/s and the average speed of Noah's car is 1.8 m/s.

Use the circuit diagram to decide if the lightbulb will light. Justify your answer

elena-14-01-66 [18.8K]

Answer:

It will.

Explanation:

For a circuit to function properly, everything has to be connected. As the diagram shows that everything is connected and there are no gaps, it will light.
