Answer: Mineral and non- mineral components circulate in the environment in different forms whether it is in the form of solid, liquid, or gas.

Explanation:

Plants take up the minerals like calcium, potassium, nitrogen, sulphur, and others from the soil and utilize them for their survival and growth. These minerals are stored in the flowers, leaves, roots, and other plant parts and these plant parts are consumed by humans and animals. So, inorganic minerals from the soil are converted into organic forms by the plants again the minerals are decomposed into inorganic forms after the death of organisms and again mineral is converted into inorganic form in the soil and these minerals can become the component of the rocks after the sedimentation of the soil.

Answer:

<h2><em><u>C. It must reflect red light wavel</u></em></h2>

Explanation:

<em>The color of the object is reflected by the object other colors are absorbed by the object.</em>

Here <em>object appears in red color so red color is reflected by the object and other colors are absorbed.</em>

The speed of sound in air on a certain stormy day is about 1130 feet per second. you see a flash of lightning striking some dist
Anna35 [415]

Answer  4,520 feet   Explanation The light and the sound were produced at the same time but sound took long to reach since is speed is much lower than the speed of light. Speed is the rate of change of distance.  So; Distance = speed × time                 = 1130 × 4                  = 4,520 feet.

What is the change in length of a 1400. m steel, (12x10^-6)/(C0) , pipe for a temperature change of 250.0 degrees Celsius? Remem
8090 [49]

Answer:

\Delta L = 4.2 m

Explanation:

As per the formula of thermal expansion we know that

L = L_o(1 + \alpha\Delta T)

so here we will have

L_o = 1400 m

\alpha = 12 \times 10^{-6} per ^oC

\Delta T = 250 degree C

so here change in the length of the rod is given as

\Delta L = L - L_o

\Delta L = L_o \alpha \Delta T

\Delta L = 1400 (12 \times 10^{-6})(250)

\Delta L = 4.2 m

A 0.42 kg shuffleboard disk is initially at rest when a player uses a cue to increase its speed to 4.2 m/s at constant accelerat
MariettaO [177]

Answer

given,

mass of the shuffleboard disk = 0.42 kg

speed of the cue is increased to = 4.2 m/s

acceleration takes over 2 m then acceleration is zero.

the disk additionally slide to 12 m

final speed of disk = 0 m/s

a) increase in thermal energy

\Delta E_t = \dfrac{1}{2}m(v_1^2-v_2^2)

\Delta E_t = \dfrac{1}{2}\times 0.42 \times (4.2^2-v_2^2)

\Delta E_t = 3.704\ J

b)  \Delta E_t = F_f.d

F_f is the frictional force

     3.704= 12.F

      F_f = 0.308\ N

increase in thermal energy for entire movement of 14 m

     \Delta E_t = 0.308\times 14

     \Delta E_t =4.312 \ J

c)  Work done on the disk by the cue

  W = \Delta KE + \Delta E_{t}

  W = \dfrac{1}{2}\times 0.42 \times (4.2^2-0^2)+ F_f \times d

  W = 3.704+ 0.308 \times 2

   W = 3.704 + 0.616

   W  = 4.32 J
