6. There are seven colors in a rainbow.

7. The kind of rainbows are formed when light strikes small raindrops with almost the same size are Supernumerary rainbows.

8.The kind of rainbows are formed when two inner reflections are done instead of one; this causes the reversal of colors in a secondary rainbow in comparison to a primary rainbow are Secondary rainbows.

9. A reflective surface that is curved inward and away from the light source is concave mirror.

10. The kind of mirror are curved outward like the bottom

Since the direction of the needle depends on the proximity of the magnet thus this test alone is insufficient to determine the stronger magnet.

A magnetic field refers to the region where the effect of a magnet is felt. The magnetic field can be observed by the use of a compass.

Now, we know that the closer the magnet is to the compass, the greater the deflection hence this test alone is insufficient to determine the stronger magnet.

Explanation:

Storm weather likely happens in the town when the air masses meet because of difference of temperature and humidity of both air masses.

When air masses move by wind, they carry different weather conditions from the weather conditions of other region. This difference in weather conditions can create a severe storm.

So we can conclude that Storm weather likely happens in the town when the air masses meet because of difference of temperature and humidity of both air masses.

After 2.5 seconds of free fall, an item will be moving downhill at a speed of 25 m/s.Option D is correct.

The change of displacement with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.

The given data in the problem is;

t(time)= 2.5 s

u(falling velocity)=0 m/sec

v(striking velocity)=?  (m/sec)

Newton's first equation of motion:

v=u+at

v=u+gt

v=10 × 2.5

v= 25 m/s downward(+ ve taken as downward)

The velocity of an object that has been in free fall for 2.5 s will be 25  m/s downward.

Hence, option D is correct.

The efficiency of steam engine is  26.66 %.

The efficiency is defined as the work done by the engine divided by the heat supplied.

Work done is the difference between the heat supplied and heat rejected.

So, efficiency η = (Qs -Qr) / Qs

Given is the heat supplied Qs = 225 Joules and heat rejected Qr =285 . then the work done is

W = 225 -225 = - 60 Joules

Efficiency η  = 60/225 x 100%

η = 26.66 %

Thus, the efficiency of the steam engine is  26.66 %.

The weight must be 288N placed on the end of the spring when it is 2m from the ground.

If an object is lifted, work is done against gravitational force. The object gains energy.

Given is a spring has a spring constant of 48 N/m. The end of the spring hangs 8 m above the ground. The final height of weight above the ground, h =2m

Using Hooke's law, expressed as

Force, F = k (x₂-x₁).

Put the values, we get

F = 48 (8-2)

F = 288 N

This force applied on the spring is equal to the weight placed on the spring.

Weight W= 288N.

Thus, the weight must be 288N.

Claim: The phases of the Moon progress from new moon to crescent moon, first-quarter moon, gibbous moon, and full moon as the Moon waxes (the amount of illumination is increasing from Earth). As the moon revolves around Earth, its sunlit surface is visible in different portions as it reveals its phases.

 Evidence: As the moon revolves around Earth, different parts of the sunlit surface of the moon can be seen. As a result, the moon's appearance changes from night to night from Earth's perspective. The moon's apparent shape changes, as well as its position in the sky.

Reasoning: Over the course of two weeks, the moon's entire appearance changes, from a bright circle to a circle sliced in half and finally to nothing.

The work done on a body when it is moved is  125J

It states that the Work done in moving a body is equal to the change in kinetic energy of the body

Kinetic energy = 1/2 mv²

Given is a body of mass m = 6kg, moving distance d =25 m in time t=5s.

Final Velocity v = 25/5 = 5 m/s

The body is initially at rest, so, final velocity is zero. Then, change in kinetic energy will be

ΔK.E = K.Ef - K.Ei

ΔK.E = 1/2 x 6 x (5)² -0

ΔK.E  =125J

According to work energy theorem, work done is

W = 125J

Thus, the work done on a body when it is moved is 125J.
