The gravitational force between two objects may be calculated by the equation,
F = G x (m1 x m2) / d²
where G is universal gravitational constant, m1 and m2 are the masses of two bodies and d is the distance between them. Substituting the known values,
9.20 x 10^-9 = (6.673 x 10^-11) (5.01 kg x m2) / (0.192m)²
The value of m2 is approximately 1.01 kg.
The truth is both of them are more reactive metal.
<span>The amount of dissolved oxygen in water may decrease
because of the increase in organic matter in the water. <span>Aquatic organisms breathe and use oxygen. Large amounts of
oxygen are consumed by the decomposition of bacteria (when there are large
amounts of dead matter to decompose, there will be a significant number of
bacteria). Examples: dead organic matter (algae), wastewater, garden waste,
oils and fats, all this results in a decrease in dissolved oxygen in the water.</span></span>
Answer:
He should stand from the center of laser pointed on the wall at 1.3 m.
Explanation:
Given that,
Wave length = 650 nm
Distance =10 m
Double slit separation d = 5 μm
We need to find the position of fringe
Using formula of distance
Put the value into the formula
Hence, He should stand from the center of laser pointed on the wall at 1.3 m.
In contrast, extratropical cyclones have their strongest winds near the tropopause, which is about 8 miles above the surface. These differences are due to the tropical cyclone being “warm-core” in the troposphere, whereas extra-tropical cyclones are “warm-core” in the stratosphere and “cold-core” in the troposphere.
