How Buoyancy force on an object is related to the weight of liquid it displaces?

Answers

Answer 1

The buoyancy force (B) is equal to the weight (W) of the fluid that a body in that fluid displaces. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy

Answer 2

Archimedes' principle is the statement that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

Do some research, and look up the difference between the zinc-carbon battery described in the lesson, and the alkaline battery (shown at the bottom), which is another common dry cell that we use every day. What are the electrodes made of in the alkaline battery? The electrolyte? Does one type have an advantage over the other? Write a short essay.

Answers

Answer:

Here it is:

The difference between a zinc battery and the alkaline battery is the type of electrolyte in them. Zinc batteries are mostly composed of ammonium chloride. But alkaline batteries use potassium hydroxide.

Alkaline-manganese, also known as alkaline, is an improved version of the zinc-carbon battery and delivers 1.5V. Lewis Urry (1927–2004) invented alkaline in 1949 while working with the Eveready Battery Company laboratory in Ohio, USA. Alkaline gives off more energy at higher load currents than zinc-carbon. The Canadian inventor Lew Urry patented the first modern primary alkaline battery in 1959.

The alkaline manganese battery utilizes electrodes of zinc and manganese dioxide, but the electrolyte is potassium hydroxide. The electrolyte of a battery consists of soluble salts, acids, or other bases in inside a liquid, in gelled and dry formats. The electrolyte also comes in a polymer, as used in the solid-state battery, solid ceramic, and molten salts as in the sodium-sulfur battery.

As expected, the capacity of both batteries is different. Because of the composition, an alkaline battery delivers more energy than a zinc battery. The only consequence of this is that both batteries should be used in different applications.

The couch weighed 500 N. How much power did he have?
A. 16,000 W
B. 1.6W
C. 800 W
D. 40 W

Answers

Answer:

$the \: answer \: for \: this \: question \: is \: d.40w$

Explanation:

Greetings !

Given values Work(W)= 800Jtime(t) = 20 secondWeight = 500N

required value power(P) = ?

Solution:

Firstly, recall the work-power equation

work=power*timew=p*t

substitute known values to the equation

(800)=P*(20)

Solve, for P (power)

P=40.0w

Hunter had a power of 40 W while pushing the couch across the room. The correct answer is D. The correct answer is 40W.

Given:

Work (W) = 800 J

Time (t) = 20 seconds

Power is the rate at which work is done or the rate at which energy is transferred. It is calculated using the formula:

Power (P) = Work (W) ÷ Time (t)

Let's calculate the power:

Power (P) = 800 ÷ 20

Power (P) = 40 W

Therefore, Hunter had a power of 40 W while pushing the couch across the room. The correct answer is D.

A boat floats south on the Amazon River at a speed of 6 m/s. The boat and
passengers have a combined mass of 540 kg.

a. What is the momentum of the boat? (Remember, momentum is a vector
quantity.)

b. The passengers paddle backward, reducing the speed to 4 m/s. What was the
impulse applied to the boat by the paddling?

Answers

Explanation:

Take south to be negative.

a. Momentum is mass times velocity.

p = mv

p = (540 kg) (-6 m/s)

p = -3240 kg m/s

p = 3240 kg m/s south

b. Impulse = change in momentum

J = Δp

Since the mass is constant:

J = mΔv

J = (540 kg) (-4 m/s − (-6 m/s))

J = 1080 kg m/s

J = 1080 kg m/s north

What fraction of the Moon model was always lit up by the light in your model?

Answers

Answer:10

Explanation:

In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.

The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.

The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.

Therefore, the fraction of the Moon that was always lit up by the light is half, or 1/2.

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline

Think it has something to do with Viscosity, Density, and Pressure but not sure what

Answers

Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)

Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.

To accurately record the location of a star, you would typically need to measure the altitude, azimuth, and time.

Altitude: The altitude refers to the angle above the horizon at which the star is located. It is measured vertically from the observer's position.

Azimuth: The azimuth refers to the horizontal angle or direction in which the star is located. It is measured clockwise from a reference direction, often north.

Time: Recording the time of observation is crucial for celestial navigation and astronomy. It helps determine the position of the star relative to Earth's rotation and allows for calculations related to the star's apparent motion.
