Describe one practical use of a concave mirror.

Tatiana [17]

Answer:

Here are some uses...

Explanation:

Uses of convex mirror:

It is used in supermarkets and stores for surveillance.

It it is used as rear view mirror in automobiles.this is due to the reason that a convex mirror provides a wider field of view than a plane or concave mirror.

Uses of concave mirror:

It is used in torches.

They are used in headlights of vehicles to send parallel rays to infinity , in shaving mirror to get an enlarged image of the face and also by dentists to see a bigger image of the tooth / teeth .

A car of mass 1200Kilograms moving at 50 m/s the driver applies the brakes for 0.08 seconds and the castles down to 10 meter per

Inessa05 [86]

Initial velocity=u=15m/s

Final velocity=v=10m/s

Time=0.08s

$\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}$

$\\ \sf\longmapsto Acceleration=\dfrac{10-15}{0.08}$

$\\ \sf\longmapsto Acceleration=\dfrac{-5}{0.08}$

$\\ \sf\longmapsto Acceleration=-62.5m/s^2$

What happens to the speed of a sound wave as it passes from the air into the ground?

meriva

Answer:

SEE BELOW

Explanation:

Sound travels faster in warmer air, so the sound waves are refracted upward, away from the ground. Various atmospheric conditions can cause a temperature inversion, with air temperature increasing with height. This causes some of the sound energy from a source near the ground to be refracted back toward the ground.

How many possible outcomes are there in rolling a spinner 1 to 8?; What is the probability of spin an even number on a 1 to 8 sp

UkoKoshka [18]

The probability of getting a prime number ( 2, 3, 5, 7) between 1 to 8 is 1/2. The total outcomes possible for spinning the spinner and tossing the coin is 16.

<h3>What is probability?</h3>

Branch of mathematics concerning numerical descriptions of how likely an event is to occur is called probability.

Total number of outcomes = 8.

Let, the probability of getting a prime number ( 2, 3, 5, 7) between 1 to 8

P(E) = (no. of outcomes) /( total no. of outcomes)

=4/8

=1/2

When a coin is tossed, there are two possible outcomes that are H(head), and T(tail).

If you spin the spinner , there are 8 possibilities.

Total outcomes = 8 * 2

=16

There are 16 outcomes, when spinning a spinner numbered from 1 to 8 and tossing a coin.

A car travels at an average speed of 60 km / h for 15 minutes. How far does the car travel in 15 minutes?

salantis [7]

Answer:

15km

Explanation:

Given parameters:

Average speed = 60km/hr

Time taken = 15min

Unknown:

Distance = ?

Solution:

The distance traveled can de derived using the expression below;

Distance = Average speed x time taken

Now let us convert the time to hr;

60min = 1hr

15min = $\frac{15}{60}$ = 0.25hr

Distance = 60km/hr x 0.25hr = 15km
