<span>The answer would be: b. biosphere, atmosphere, and geosphere

The biosphere is made by the ecological system so the plants should be biosphere. The carbon dioxide is taken by the plant from the air which was the atmosphere. The nutrient is taken by the plant from the soil which is the geosphere.</span>

A body of mass 5.0 kg is suspended by a spring which stretches 10 cm when the mass is attached. It is then displaced downward an

Dominik [7]

Answer:

position as a function of time is y = 0.05 × cos(9.9)t

Explanation:

given data

mass = 5 kg

length = 10 cm = 0.1 m

displaced = 5 cm

to find out

position as a function of time

solution

we will apply here equilibrium that is

mass × g = k × length

put here value and find k

k = $\frac{5*9.8}{.01}$

k = 490 N/m

and ω is

ω = $\sqrt{\frac{k}{m} }$

ω = $\sqrt{\frac{490}{5} }$

ω = 9.9

so here position w.r.t time is

y = 0.05 × cosωt

y = 0.05 × cos(9.9)t

so position as a function of time is y = 0.05 × cos(9.9)t

What had to be invented before we could discover Saturn and Neptune?

Ann [662]

The discovery of Uranus, Neptune, most asteroids, the moons of
any planet other than Earth, Pluto, and all the other dwarf planets,
required the invention and use of telescopes. Those objects are all
too dim to be seen with a bare naked human eye.

Saturn is bright and plainly visible with your eyes, if you know when
and where to look, and what you're looking at.

Find the kinetic energy ofan electron that moves at half the speed of light to four significant digits.

Vlad1618 [11]

Answer:

Ke=electron kinetic energy= $10.24*10^{33} J$

Explanation:

The electron has a mass of $9.1*10^{-31} kg$

The speed of light in a vacuum is a universal constant with the value 299 792 458 m / s (186 282,397 miles / s), although it is usually close to $3*10^{8} \frac{m}{s}$

Kinetic energy (K) is the energy associated with bodies that are in motion, depends on the mass and speed of the body and is calculated using the formula:

$K=\frac{1}{2} *m*v^{2}$ Equation(1)
