Suppose that we repeat the experiment shown in the video, but we replace one of the cylinders with a cylinder that has twice the radius (and use larger containers of water). If the height of the original cylinder is \rm h, how deeply must we submerge the new cylinder to get the same weight reduction as in the video?

Answers

Answer 1

Answer: 1/4h is the answer
hope it helps

A block of wood has a volume of 125 cm has a mass of 27 g. What is the density of this block ?

Answers

Answer:

27/125

(3/5)³

(0.6)³

0.216 gm/cm³ or g/cc

Explanation:

Given:
Volume = 125 cm³
mass: 27 grams

Here Density is actually the amount of matter present in unit volume.

Mathematically, rho(like p) (tapering downwards) = Mass/Volume
Putting, 27/125 g/cm³

0.216 g/cc

PLLLZ HELP Compare and contrast electric potential energy and electric potential difference? Please use 2 content related sentences

Answers

The electric potential difference is the electric potential energy per unit charge

Explanation:

First of all, we define the concept of electric potential. The electric potential is a measure of the gradient of the electric field at a certain point of the space. The electric potential at a distance $r$ from a positive charge of magnitude $q$ is given by

$V(r) = (kq)/(r)$

where k is the Coulomb's constant.

Now we can define the electric potential energy and the electric potential difference:

Electric potential energy is the energy possessed by a charge due to the presence of an electric field. For a charge of magnitude $q$ immersed in an electric field, its potential energy is given by $U=qV$ , where V is the electric potential at the location of the charge.
The electric potential difference is simply the difference in electric potential between two points in the space. For instance, if the potential at point A is V(A) and the potential at point B is V(B), then the potential difference is $\Delta V = V(A)-V(B)$

The electric potential energy is also defined as the work done on a charge q moved through a potential difference of $\Delta V$ . Consequently, the potential difference $\Delta V$ represents the work per unit charge done, i.e. the work done when moving a unitary charge through a potential difference $\Delta V$ .

What is the resistance of an ideal ammeter voltmeter ?

Answers

All the current being measured has to flow through the ammeter. So in order to avoid
any change in the circuit caused by the ammeter, its resistance should ideally be zero.

The voltmeter measures the voltage between two points. It must be connected
between those points, and in parallel with everything between them in the circuit.
In order to avoid any change in the circuit caused by the voltmeter, its resistance
should ideally be infinite.

Final answer:

An ideal ammeter has zero resistance to avoid altering the current it measures, while an ideal voltmeter has infinite resistance to prevent drawing current from the device it's measuring the voltage of.

Explanation:

The resistance of an ideal ammeter is zero ohms. This ensures that it doesn't interfere with the current it is measuring. An ammeter is connected in series with the circuit, and if the resistance were greater than zero, it would decrease the amount of current circulating in the circuit.

On the other hand, an ideal voltmeter has infinite resistance. This happens because a voltmeter is connected in parallel with a device to measure its voltage, and to avoid drawing current from the device, an ideal voltmeter should have infinite resistance.

Analyze how heat transfer occurs during the processes of conduction and convection.

Answers

During conduction, two substances are in direct contact with one another. When the molecules begin to gain more energy, they move around more and as they bump into one another, energy gets transferred.
During convection, a continuous current (convection current) transfers heat energy through a liquid/gas. The heat rises, and meets cooler areas.
