Answer:

=1.068 ×10⁻¹³N

Explanation:

Force of gravity =Gm₁m₁/d² where G is the universal gravitation constant =G = 6.673 x 10-11 N m²/kg², m₁ and m₂ is the mass of object 1 and 2 respectively and d is the distance between them. First we change the distance into SI units i.e meters 25 km= 25000 m

F= (6.673 x 10⁻¹¹ N m²/kg²×1000 kg×1000 kg)/ (25000 m)²

=1.068 ×10⁻¹³N

Lead is a toxic metal that affects the central nervous system. A Pb-contaminated water sample contains 0.0012 % Pb by mass. What
hram777 [196]

Answer:

8.3 × 10³ mL

Explanation:

Step 1: Calculate the mass of water that contains 100 mg of Pb

The concentration of Pb in the sample is 0.0012% by mass, that is, there are 0.0012 g of Pb every 100 g of water. The mass of water that contains 100 mg (0.100 g) of Pb is:

0.100 g Pb × 100 g Water/0.0012 g Pb = 8.3 × 10³ g Water

Step 2: Calculate the volume corresponding to 8.3 × 10³ g of water

Since the solution is diluted, we will assume the density of the sample is equal than the density of water (1 g/mL).

8.3 × 10³ g × 1 mL/1 g = 8.3 × 10³ mL

Which of the three substances has the greatest porosity?
MArishka [77]
<h2>Answer:</h2>

<u>Most porous is gravel</u>

<h2>Explanation:</h2>

Porosity tells us how much water rock or soil can retain. It tells us about the spaces among the grains. Gravel is more bigger than sand or silt. Its grains are arranged in such a manner that their integral spaces are very bigger so they are more porous. Clay is the most porous but since it is not mentioned in the option so after clay comes the gravel. Usually gravel and sand has equal porosity.
