What is the correct answer in scientific notation? 1.2x104 x 1.2x108 =

1 answer:

5 0

Step one: Gather like terms
1.2×104×1.2x xx108
Step 2: Use Product rule: xaxb=xa+b
1.2×104×1.2x1+1+108 
Step 3: Simplify 1+1+108 to 110
1.2×104×1.2x110
Step 4: Simplify
You answer will be: 149.76x110

Answer:

Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:

Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.

Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg

parantesis () or brackets [].

Common compound names.

Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.

Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.

Computing molecular weight (molecular mass)

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.

Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.

Definitions of molecular mass, molecular weight, molar mass and molar weight

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)

Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Weights of atoms and isotopes are from NIST article.

A 1,500-kilogram car travelling at 10 meters per second (about 22 mph) strikes a parked car on the side of the road. If the car

Alona [7]

The force exerted on the parked car by the moving car is –30000 N

To solve this question, we'll begin by calculating the deceleration of the moving car. This can be obtained as follow:

Initial velocity (u) = 10 m/s

Final velocity (v) = 0 m/s

Time (t) = 0.5 s

<h3>Deceleration (a) =?</h3>

$a = \frac{v - u}{t} \\\\ a = \frac{0 - 10}{0.5}\\\\a = \frac{- 10}{0.5}$

Finally, we shall determine the force exerted by the moving car on the parked car. This can be obtained as follow:

Mass of moving car (m) = 1500 Kg

Acceleration (a) = - 20 m/s

<h3>Force (F) =.?</h3>

F = ma

F = 1500 × (-20)

NOTE: The negative sign indicate force is in opposite direction to the parked car.

Therefore, the force exerted on the parked car by the moving car is –30000 N
