Explanation:
130km = (0.621 * 130) mi = 80.73 mi
So if you drive at 80.73 mph you will get a ticket for speeding over the limit.
Hi
only compound must two different atom.
Element have made by only single atom.
_________________________________
Compound:
A compound is formed when two or more elements chemically combine together. The elements react chemically and form chemical bonds between the atoms of the elements.
A mixture is a combination of two or more substances which are not chemically the same. ____________________________________
Homogeneous mixtures:
Homogeneous mixtures have uniform composition and appearance throughout .A homogeneous mixture is also called a true solution.
Example: sugar solution, ocean water, soft drinks, etc.
____________________________________
Heterogeneous mixtures:
Heterogeneous mixtures consist of different substances.
Examples: mixture of iron and sulphur, mixture of sand and table salt, etc.
so only elements are single atom.
all these are combination of atoms.
thanks for asking
Answer:
Explanation:
given,
inductance of solenoid = 2.07 μ H
winding of the wire = 1.19 m
Using formula of inductance
L is the inductance
N is number of turns of the coil
μ₀ is permeability of free space
L is length of winding
N (2π r) = 1.19
squaring both side
4π(N²(πr²))=1.19²
N² A = 0.113
now
