The number of protons in an atom is known as the atomic number
Explanation:
Given that,
Wavelength of the light, 
(a) Slit width, 
The angle that locates the first dark fringe is given by :



(b) Slit width, 
The angle that locates the first dark fringe is given by :



Hence, this is the required solution.
44.64m
Explanation:
Given parameters:
Mass of the car = 1500kg
Initial velocity = 25m/s
Frictional force = 10500N
Unknown:
Distance moved by the car after brake is applied = ?
Solution:
The frictional force is a force that opposes motion of a body.
To solve this problem, we need to find the acceleration of the car. After this, we apply the appropriate motion equation to solve the problem.
-Frictional force = m x a
the negative sign is because the frictional force is in the opposite direction
m is the mass of the car
a is the acceleration of the car
a =
=
= -7m/s²
Now using;
V² = U² + 2as
V is the final velocity
U is the initial velocity
a is the acceleration
s is the distance moved
0² = 25² + 2 x 7 x s
0 = 625 - 14s
-625 = -14s
s = 44.64m

The elements fluorine and chlorine can form minerals in the "halide"group
.
Halide refers to the group containing halogens. The halogens turn out to be less responsive as you go down the group. Fluorine, at the highest point of the group, is the most responsive or reactive halogen. It is to a great degree risky, causing serious synthetic consumes on contact with skin.
Halogens also act as bleaching agents.They will evacuate the shade of colors. Chlorine is utilized to bleach wood mash to influence white paper.
