When the speed of the particle is close to that of light, it's observed mass would be infinitely large.

To answer the question, we need to know what observed mass is.

This is the mass the body of an object in relativistic motion appears to have.

So, observed mass, m' = m/√(1 - β²) where

Now, since the speed of the particle is close to that of light, β ≅ 1.

So, m' = m/√(1 - β²)

m' = m/√(1 - 1²)

m' = m/√(1 - 1)

m' = m/√0

m' = m/0

m' = ∞

So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.

Answer:

Using magnets to repel each other is one way to try to achieve a frictionless bearing.  In practice, it can be difficult to remove all friction.  While a pair of magnets will repel each other, they are not stable in this condition.  One magnet won't simply float forever above another magnet.

The mass in grams of He are necessary to fill a balloon having a volume of 4.50×10³ mL to a pressure of 1.14×10³ torr at 25.0ºC is 1.104 grams.

Mass (W) in grams from moles (n) will be calculated by using the below equation:
n = W/M, where

M = molar mass

Moles of helium gas will be calculated by using the ideal gas equation:

PV = nRT, where

R = universal gas constant = 62.363 L.torr / K.mol

P = pressure of gas = 1.14×10³ torr

V = volume of gas = 4.50×10³ mL = 4.50 L

n = moles of gas = ?

T = temperature = 25.0ºC = 298 K

On putting these values on the ideal gas equation, we get

n = (1140)(4.5) / (62.363)(298) = 5130 / 18584

n = 0.276 moles

Now we convert this moles into mass by using the first equation as:

W = (0.276mol)(4g/mol) = 1.104 g

Hence required mass of helium gas is 1.104 grams.

Given what we know, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.

This has to do with the natural way in which fires spread. Fires that occur naturally or accidentally tend to concentrate in one place, then spread throughout the warehouse over time, however, this is not what the detective found. Instead, there are indications that multiple fires started simultaneously.

Therefore, given the very unlikely nature of this occurring naturally, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.

Okay, so here we have Modernity is even McGarity is equal to 0.5 M and we have volume, so Volume is equal to 200 mililiters  is equal to 0.1 liter  Okay, so they are asking to calculate the mass of what u have  Okay. So first of all, if we want to calculate the mass of then we have to calculate the number of moles. So maturity is equal to the number of moles per volume in liters . So you mean zero point sorry from this one number of moles is equal to So N is equal to m multiplied very weak. So that is equal to 0.1 and 0.5. So that is equal to 0.05 moles. Okay, now the mask is equal to the mass of cool eh is equal to the number of Okay. Number of 0.5 and it is multiplied by 92 g per mole. Then it is equal to 9.6 g. So this is the mass of a present.

Answer:

woodpecker it's easy lil lol

In the given chemical reaction iron is less electropositive metal and aluminum is more electropositive and behave as a reducing agent also.

Electropositivity is the ability of an atom of donation or losing of electrons easily.

From the given chemical reaction it is clear that oxidation state of iron changes from +3 to 0 & of aluminum is from 0 to +3. So in the above chemical reaction aluminum is more electropositive than iron metal. And aluminum is behave as a reducing agent as it helps in the reduction process by providing electrons.

Hence aluminum is electropositive metal and reducing agent, iron is less electropositive.

To determine the substance that comprises the anode and the cathode in a galvanic cell is by determing ;

The material with the larger (more positive) standard reduction potential that will be the cathode.

In a galvanic cell, oxidation which leads to the loss of elctrons occurs at the anode, while reduction ( addition of elctrons ) occurs at the cathode. therefore the materials with a more positive standard reduction potential will be the cathode of the galvanic cell.

Hence we can conclude that The material with the larger (more positive) standard reduction potential will be the cathode.
