krek1111 [17]

Answer:

14.56 N

Explanation:

According to Newton's second law of motion,

The force acting on a body is equal to the product of its mass and acceleration acting on it.

Weight of a body on a planet is equal to the force due to gravity of the planet. So, weight is the product of mass of body and acceleration due to gravity of the planet.

Here, acceleration due to gravity on planet A is g_{A}=5.6 m/s² and mass of an object on it is m=2.6 kg.

So, weight of an object, W, on planet A is given as,

W=m\times a=m\times g_{A}=2.6\times 5.6=14.56\textrm{ N}

The mass of a sample of sodium bicarbonate is 2. 1 kilograms (kg). There are 1,000 grams (g) in 1 kg, and 1 Times. 109 nanograms
slega [8]

2.1 kg of sodium bicarbonate is equal to the 2.1 x 10¹² ng of sample. Option D is correct.

Mass is the quantity of the substance in the body or object. The SI unit of mass is Kilogram.

There are other units of measure,

  • Milligram: 1 g is equal to the \bold {10^3 \ mg}
  • Micro-gram: 1 g is equal to \bold {10^{6} \ \mu g}
  • Nano-gram: 1 g is  is equal to\bold {10^{9} \ ng}

First convert kg to gram,

Since, 1 Kg = 1000 g

2.1 kg = grams of sample

So,

Do the cross multiplication,

\rm mass\ of\ sample = \dfrac {2.1\ kg \times  1000\ g }{ 1 kg}\\\\\rm mass\ of\ sample =2100 g

Now, convert 2100 g to nano-grams

Since, 1 g = 1 x 10⁹ ng

2100 g = ng of sample

So,

Do the cross multiplication,

\rm mass\ of\ sample  = \dfrac {2100 g \times  1 \times  10^9 ng }{1\ g}\\\\\rm mass\ of\ sample  = 2.1 \times 10^1^2 ng

Therefore, 2.1 kg of  sodium bicarbonate is equal to the 2.1 x 10¹² ng of sample.
