# Frog and Horse Trough Questions

• imnotsmart
In summary, the first question involves a frog in a hemispherical pod floating in a fluid with a density of 1.25 g/cm3. The mass of the frog can be calculated by finding the buoyancy force, which is equal to the weight of the fluid displaced by the pod. To find this, the volume of the immersed body needs to be known. The second question involves a cowboy filling a horse trough using a hose with a diameter of 1.9 cm and water flowing at 1.4 m/s. The time it takes to fill the trough can be calculated by knowing the volume of the trough and the flow rate of the hose.

I have two more questions for anyone can help...
1. A frog in a hemispherical pod finds that he just floats without sinking in a fluid of density 1.25 g/cm3. If the pod has a radius of 9.00 cm and negligible mass, what is the mass of the frog?
2. A cowboy at a dude ranch fills a horse trough that is 1.6 m long, 60 cm wide, and 40 cm deep. He uses a 1.9 cm diameter hose from which water emerges at 1.4 m/s. How long does it take him to fill the trough?

Just need some direction...no answer.

For the first problemINT:The buoyancy force must be equal to the gravity force...

For the second:what is the colume of the trough?What is the flow through the hose...?

I still don't understand how you begin the problem...do you divided 9 cm by 1.25 g/cm^3?

Firstly, you must understand the definition of The buoyancy force. Do you know what that is and how to calculate it ?

Anyone help?

Yeah.U've been asked 2 questions above.Can u answer them?

Daniel.

Yeah, the pod partially submerged in the fluid experiences the bouyant force equal in magnitude to the weight of the fluid displaced by the pod.
To calculate it B=PfluidVg=wfluid ?

$F_{B}=\rho_{fluid}V_{body}g$...

And u need to know the volume of the immersed body.

Daniel.

how do you find the volume of the immersed body?

I can only assume that all the hemisphere is immersed.The problem is not to explicit,so you have to make assumptions,in order to get a result.

## 1. What is the purpose of a frog and horse trough?

A frog and horse trough is a container typically used for holding water for livestock such as horses and for breeding and raising frogs. It is also used as a decorative feature in gardens and yards.

## 2. How do you properly care for a frog and horse trough?

To care for a frog and horse trough, it is important to regularly clean and refill the water to prevent stagnant water. You should also remove any debris or algae buildup to maintain a healthy environment for the animals.

## 3. Can frogs and horses share the same trough?

No, it is not recommended for frogs and horses to share the same trough. Frogs require different water conditions than horses and can also carry diseases that can harm horses.

## 4. What types of frogs can live in a trough?

There are many species of frogs that can live in a trough, including tree frogs, bullfrogs, and green frogs. It is important to research and choose a species that is suitable for the climate and water conditions in your area.

## 5. How can a frog and horse trough benefit the environment?

A frog and horse trough can benefit the environment by providing a water source for wildlife, such as birds and insects. It can also serve as a breeding ground for frogs, which are important for controlling insect populations. Additionally, a trough can be used to collect rainwater for gardening and other purposes, promoting sustainability.
