Most of the light reflects back and form a virtual image !!

Answer: When light rays strike a smooth, opaque surface such as a mirror, most of the rays <u>reflect back</u> forming <u>a virtual image</u>.

Explanation:

When light rays strike a smooth surface such as mirror, the light cannot pass through as it is opaque. Most of the light is reflected back. A mirror is made up of glass with highly lustrous metal polished at the back.

The image formed by a mirror is not real as it cannot be obtained on a screen. It is virtual in nature, forms behind the mirror. The image is of same size and at the same distance from the mirror as the object is.

Jenny and Alyssa are members of the cross-country team. On a training run, Jenny starts off and runs at a constant 3.8 m/s. Alys
guapka [62]

Answer:

285 seconds

Explanation:

Jenny speed is 3.8 m/s

Alyssa speed in 4.0 m/s

Alyssa starts after 15 seconds

Find the distance covered by Jenny, when Alyssa starts

Distance=Speed*time

Distance covered by Jenny in 15 seconds= 3.8×15=57m

Relative speed of the two members heading same direction will be;

4.0m/s-3.8m/s=0.2m/s

To find the time Alyssa catch up with Jenny you divide the distance to be covered by Alyssa by the relative speed of the two

Distance=57m, relative speed=0.2m/s  t=57/0.2 =285 seconds

=4.75 minutes

Answer:

A. quality of road-making material

Explanation:

The CBR method of flexible pavement design gives an idea about the:

A. quality of road-making material

B. traffic intensities

C. characteristics of soil

D. All of the above

The California Bearing Ratio (CBR) test is a penetration test used to evaluate the subgrade strength of roads and pavements. The results of these tests are used with the curves to determine the thickness of pavement and its component layers. it is the measure of the resistance of a material against the penetration of a standard plunger.

This can be used to determine the quality of road making material. CBR is expressed as the percentage of the actual load to the standard load.

An object has 100 J of kinetic energy and a mass of 2 g. How fast was it traveling?
iragen [17]

K.E = 1/2 mv²

100   = 1/2 (2 )(v)²

100  = both  2 cancel (v)²

Taking Square root on b/s

√100 = √v²

10  = v
