Is it inhumane to keep a cat in one room?

1 answer:

4 0

So there are a couple of variables to that question. if the room has everything a cat needs then no. if it had food, water, a bed, stuff to keep it occupied, a litter box, sunlight, and some other form of life to keep it company then no it wouldn't be.
But if you locked it in a dark room without any of that stuff yes the cat would die

How much time should be allowed for a 605-mile car trip if the car will be traveling at an average speed of 55 miles per hour?

lesya692 [45]

To find how long it will take for the trip divide miles by the speed.

605 / 55 = 11

So it will take 11 hours to get to the destination.

With "normal" gravity, we used a potential energy of mgh. Now with the gravity that is more accurate over longer distances we us

Artemon [7]

Answer:

A general solution is $\Delta U=mh\frac{GM}{r^{2}}\frac{r}{r+\Delta h}$ and a particualr case is mgh, it is just to distance around the radius Earth.

Explanation:

We can use a general equation of the potential energy to understand the particular and general case:

The potential energy is defined as $U=-\int F\cdot dx$ , we know that the gravitational force is $F=GmM/r^{2}$ , so we could find the potential energy taking the integral of F.

$U=-GmM/r$ (1)

We can find the particular case, just finding the gravitational potential energy difference:

$\Delta U=U_{f}-U_{i}$ . Here Uf is the potential evaluated in r+Δh and Ui is the potential evaluated in r.

Using (1) we can calculate ΔU.

$\Delta U=-\frac{GmM}{r+\Delta h}+\frac{GmM}{r}$

Simplifying and combining terms we have a simplified expression.

$\Delta U=mh\frac{GM}{r^{2}}\frac{r}{r+\Delta h}$ (2)

Let's call $g=\frac{GM}{r^{2}}$ . It is the acceleration due to gravity on the Earth's surface, if r is the radius of Earth and M is the mass of the Earth and we can write (2) as ΔU=mgh, but if we have distance grader than r we should use (2), otherwise, we could get incorrect values of potential energy.

I hope i hleps you!
