Answer:

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.

Answer:

The energy conservation law is a consequence of the shift symmetry of time; energy conservation is implied by the empirical fact that the laws of physics do not change with time itself.

A television has a mass of 19 kg. What is the weight of the television?
soldi70 [24.7K]
That depends on how far it is from the nearest planet. If it's on the surface of Earth, it weighs (19 kg) x (9.8 m/s^2) = 186.2 newtons.

How much pressure is applied to the ground
statuscvo [17]

Answer:

Pressure applied by the man= 285103.125 Pa  or 41.35 lb/in^{2}

Explanation:

Pressure is defined as the perpendicular force applied per unit area.

i.e.  Pressure=\frac{Force}{Area}

Now, Force= mg

where, m = mass of the body(man) = 93 kg

g = acceleration due to gravity of Earth = 9.81 m/{s^{2}}

Area covered is equal to the area of both stilts(a man generally stands on two feet)

therefore Area=2(0.04)^{2} m^{2}

and putting in the values, we get,

Pressure=\frac{93\times9.81}{2\times(0.04)^{2}}Nm^{-2}=285103.125Nm^{-2}

Now we need to convert to our required units:

1Nm^{-2}=1Pa\\1Pa=0.000145038lb/in^{2}

(We can get the above result by individually converting kg to lb and meters to inches respectively)

Using the above relations we get,

Pressure=285103.125Pa=0.000145038\times285103.125lb/in^{2}=41.35lb/in^{2}

A compound is discovered and its molecular weight is determined to be 526g/mol. however, one of the elements has not yet been id
AfilCa [17]

Sulphur

The missing element is sulphur

Here the compound is composed of  element X and chlorine.

it is given,

XCl (6) ----> 6Cl

mass = 13.1%

it is X and Cl = 100%-13.10%

                     = 86.90%

chlorine = 86.90            

X = 13.10

We assume 100g of sample

so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.

now we split that chlorine into two moles of chlorine.

  • Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that.
  • We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six.
  • we discover that we have  0.4086 moles of X when we divide this by six.
  • We obtain those moles of X from 13.10 g of X.  
  • Given that Mueller masses grams per mole, I can compute the molar mass.
  • 13.10 grams of X are contained in 0.4086 moles of X.
  • Or, to put it another way, each remote has a molar mass of 32–06 grams.
  • The element with this molar mass is sulfur, as I can see from the periodic table.
  • Okay, so the element we're looking for in this situation is sulfur.
