<h3>Answer;</h3>

A black T-shirt 

<h3>Explanation;</h3>

Materials can be either reflectors and absorbers of waves such as light waves, sound waves etc. Reflectors are those materials that reflects waves, such that the waves bounces back on hitting the surface of those materials.
Examples of such materials are those with smooth and shiny surfaces, while those with rough and opaque surfaces are poor reflectors of light. Additionally, these materials that are good reflectors are poor absorbers while those that are poor reflectors are good absorbers of light.
Dull surfaces are the best emitters and absorbers of light but the worst reflectors of light waves. White surfaces or polished surfaces are bad and worst emitters and absorbers of light waves respectively

Jake calculates that the frequency of a wave is 500 hertz and that the wave is moving at 1,250 m/s. What is the wavelength of th

Neko [114]

Frequency (f) = 500 hz (SI)
Velocity (V) = 1250 m/s (SI)
Wavelength (Lambda) = ? meters

$v = \lambda \times f$
$1250 = \lambda \times 500 \\ \lambda = 1250 \div 500 \\ \lambda = 2.5 \: meters$

After the box comes to rest at position x1, a person starts pushing the box, giving it a speed v1. when the box reaches position

KiRa [710]

As we know by work energy theorem

total work done = change in kinetic energy

so here we can say that wok done on the box will be equal to the change in kinetic energy of the system

$W_p = KE_f - KE_i$

initial the box is at rest at position x = x1

so initial kinetic energy will be ZERO

at final position x = x2 final kinetic energy is given as

$KE_f = \frac{1}{2}mv_1^2$

now work done is given as

$W_p = \frac{1}{2}mv_1^2 - 0$

so we can say

$W_p = \frac{1}{2}mv_1^2$

so above is the work done on the box to slide it from x1 to x2

What is matter explain verifly

marysya [2.9K]

Answer:

Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.Matter can exist in several states, also called phases. The three most common states are known as solid, liquid and gas.Matter is the Stuff Around You or Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).Solid ice, water and steam are few examples of matter touched in everyday life. Subatomic particles are also considered as matter.
