Little Timmy wants to measure how tall his house is. He doesn’t have a tape measure but does have a stopwatch. He recruits Big B
Komok [63]

The distance covered by an object accelerating from rest is

D = (1/2) · (acceleration) · (time)² .

In this particular case, 'acceleration' is 9.8 m/s² ... due to gravity.

D = (1/2) · (9.8 m/s²) · (1.67 s)²

D = (4.9 m/s²) · (2.789 s²)

D =  13.67 meters

What is the difference between an object’s speed and its acceleration? NO LINKS
Arisa [49]

Answer: Hello! An objects speed is constant and has the units meters per second (m/s); thus, it does not change overtime. Acceleration is a rate of change where the speed does either increase or decrease overtime from its inital value; its units are meters per second second (m/s/s). I hope that helps!

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.

Which of the following methods of soil conservation uses the roots of plants as anchors in the soil? (2 points) Adding fertilize
julsineya [31]
I believe the correct answer is the second option. Planting of trees on sloped surfaces is a method of conservation that utilizes the roots of plants. Planting trees on such areas would prevent hazards and maintain the soil formation future since the roots would hold the soil together preventing or minimizing any soil erosion.
