What is the blocks average speed nearest hundredth of a m/s

Chemistry
1 answer:
bezimeni [28]2 years ago
6 0

The question is incomplete, the complete question is;

A block is pulled 0.90 m to the right in 2.5 s. What is the blocks average speed to the nearest hundredth of a m/s

Answer:

0.36 m/s to the hundredth place

Explanation:

Now let us remember the definition of speed. Speed is defined in physics as distance/time.

Here we have the distance as 0.9 m

We have the time as 2.5 s

Hence the average speed is obtained from;

Speed = 0.9/2.5 = 0.36 m/s to the hundredth place

The molarity (M) of an aqueous solution containing 22.5 g of sucrose (C12H22O11) in 35.5 mL of solution is ________.
Nonamiya [84]

Answer:

1.86 M

Explanation:

From the question given above, the following data were obtained:

Mass of sucrose (C12H22O11) = 22.5 g

Volume of solution = 35.5 mL

Molarity of solution =?

Next, we shall determine the number of mole in 22.5 g of sucrose (C12H22O11). This can be obtained as follow:

Mass of sucrose (C12H22O11) = 22.5 g

Molar mass of C12H22O11 = (12×12) + (22×1) + (16×11)

= 144 + 22 + 176

= 342 g/mol

Mole of C12H22O11 =?

Mole = mass /Molar mass

Mole of C12H22O11 = 22.5 /342

Mole of sucrose (C12H22O11) = 0.066 mole

Next, we shall convert 35.5 mL to litres (L). This can be obtained as follow:

1000 mL = 1 L

Therefore,

35.5 mL = 35.5 mL × 1 L / 1000 mL

35.5 mL = 0.0355 L

Thus, 35.5 mL is equivalent to 0.0355 L.

Finally, we shall determine the molarity of the solution as follow:

Mole of sucrose (C12H22O11) = 0.066 mole

Volume of solution = 0.0355 L.

Molarity of solution =?

Molarity = mole /Volume

Molarity of solution = 0.066/0.0355

Molarity of solution = 1.86 M

Therefore, the molarity of the solution is 1.86 M.

Suppose Gabor, a scuba diver, is at a depth of 15m15m. Assume that: The air pressure in his air tract is the same as the net wat
alexandr1967 [171]

Answer:

The ration of molar concentration is "2.5".

Explanation:

The given values are:

Average density of salt water,

= 1.03 \ g/cm^3

Net pressure,

= 2.00 \ atm

Increase in pressure,

= 1.00 \ atm

Now,

The under water pressure will be:

=  \frac{15 \ m}{10}\times 1 \ atm +1 \ atm

=  1.5\times 1+1

=  1.5+1

=  2.5 \ atm

hence,

The ratio will be:

=  \frac{(\frac{n}{V})_{15m} }{(\frac{n}{V})_{surface} }

or,

=  \frac{P}{P_s}

=  \frac{2.5}{1}

=  2.5

Which phrase is the best description of a topographic map? A shows the physical features of the land B shows political boundarie
Black_prince [1.1K]

A shows the physical features of the land

Explanation:

A topographic map is a map that shows the physical features of the land area. Rivers, streams, mountains, valleys, hills and other physical features.

  • A topographic map is made up of series of contour lines.
  • The contour lines are lines that joins places of equal elevation.
  • All places on the contour lines have the same elevation.
  • Using the contour lines, we can understand the landforms in an area.
  • Other map keys are used to delineate settlement patterns, streams, churches, dams and the like.
  • Most topographic maps are used as base maps for making other maps.
