A 2.0 µF capacitor is charged through a 50,000 ohm resistor. How long does it take for the capacitor to reach 90% of full charge
Nesterboy [21]

Answer:

0.23 s

Explanation:

First of all, let's find the time constant of the circuit:

\tau=RC

where

R=50,000 \Omega is the resistance

C=2.0\mu F=2.0\cdot 10^{-6}F is the capacitance

Substituting,

\tau=(50,000 \Omega)(2.0\cdot 10^{-6}F)=0.1 s

The charge on a charging capacitor is given by

Q(t)=Q_0 (1-e^{-t/\tau} ) (1)

where

Q_0 is the full charge

we want to find the time t at which the capacitor reaches 90% of the full charge, so the time t at which

Q(t)=0.90 Q_0

Substituting this into eq.(1) we find

0.90 Q_0 = Q_0 (1-e^{-t/\tau})\\0.90=1-e^{-t/\tau}\\e^{-t/\tau}=1-0.90=0.10\\-\frac{t}{\tau}=ln(0.10)\\t=-\tau ln(0.10)=(0.1 s)ln(0.10)=0.23 s

Im not gonna write for you a whole short story (I don't have time), but just describe what you observed (in a fake reality).

For the relationship between the predator-prey: you could say a snake eating a mouse. 

Commenalism: lets say...moss grows on a tree and benefits, but it doesn't hurt or effect the tree.

Mutalism: a bird on a rhino. The bird eats parasites and bugs that feed off the rhino, the bird gets food and the rhino stays clean and parasite free.

Parasitism: a dog and a flea. Only the flea benefits from the dog. The dog has to suffer from the parasites evilness. 

Now just thread it together and describe it. Comparing is easy, just use the definition of, for example, commensalism, mutalism, in one relationship, one organism benefits, in the other, both benefit.
Have fun!

Morgarella [4.7K]

Answer:No, the slope won't be too steep

Explanation:

Force is an external agency that causes a body to change its position while friction is a force that causes a body to slide over another. This force is called the frictional force (Ff). The force that causes a body to move is the moving force (Fm).

The slope will be too steep if the frictional force is greater than the moving force since the frictional force tends to oppose the moving force.

According to the explanation, we need to get Ff and compare with the moving force along the plane.

If Ff>Fm it means the slope will be too steep but if Ff<Fm, the slope won't be too steep and as such the body can easily be moved along the plane.

Resolving forces acting along the plane we have FmSintheta + Ff = Fm (FmSintheta and Ff are added because they act in the same direction along the plane)

Fm=50N, theta=5°

Imputing this into the formula to get Ff;

50sin5°+Ff =50

Ff= 50-50sin5°

Ff= 50-4.35

Ff= 45.65N

Since Ff<Fm, this means the slope is not too steep and as such the 30kg load can be moved along the plane easily.
