Answer:

Decomposers

Explanation:

Decomposers are organisms that gives the soil essential nutrients for new plants to grow.

These are micro-organisms that takes up dead and decaying organisms. They break and reduce them down into useful soil organic matter.

Organic matter are the remains of plants and animals that are very vital in the soil. They provide nutrients needed for plant growth.

Complex organic molecules are broken down into simple and useful ones which are needed for the growth of plants.

An occupant of a car has a chance of surviving a crash if the deceleration during the crash is not more then 30 g. Calculate the

sweet [91]

Answer:

20,850 N

Explanation:

We can solve the problem by using second Newton's Law:

$F=ma$

where

F is the force

m is the mass

a is the acceleration

In this problem, we have:

m = 70 kg is the mass

$a=-30 g=-30 (9.8 m/s^2)=-294 m/s^2$ is the acceleration (which is negative, because it is a deceleration)

So, we can use the equation above to find the force:

$F=(70 kg)(-294 m/s^2)=-20580 N$

and the negative sign simply means that the force is in the opposite direction to the motion.

Answer:

$R=803k\Omega$

Explanation:

We have the following information,

$V_0 = 12V\\V=10V\\c= 1.25*10^{-6}F\\t=1.8s$

We apply the equation for capacitor charging the voltage across it,

$V=V_0 (1-e^{-t/x})\\e^{-t/x}=1-(\frac{V}{V_0})\\-\frac{t}{Rc}=ln(\frac{V}{V_0})\\R=-\frac{t}{ln(\frac{V}{V_0})*c}$

Replacing values,

$R=-\frac{1.8}{ln(10/12)*1.25*10^{-6}}$

$R=803k\Omega$
