Answer:
The atomic number is the number over the symbol of the element in the periodic table and the atomic mass the number under it. An isotope is an atom with more or less neutrons than its regular form. a neon atom with mass number of 22 will have 12 neutrons in the nucleus and 10 protons, draw it with its 10 electrons. Two electrons go in the first level of energy and eight in the second. Draw a nucleus with 10 protons and 12 neutrons and an arc with 2 electrons around it and another arc with 8 electrons over the first arc.
The distance travelled by the baseball is 221 m.
<u>Explanation:</u>
Speed is the ratio of distance travelled to the time taken to cover any distance. So here the speed is given as 96 m/s and time is given as 2.3 seconds. Thus, we can determine the distance as product of speed with time.
Thus, distance = speed × Time
As the speed is 96 m/s and time is 2.3 seconds.
The distance = 96 × 2.3 =220.8 m
If we approximate it, the distance is 221 m. Thus, the distance travelled by the baseball is 221 m.
Option D is correct. P wave can travel through liquids. P stand for the primary of pressure wave.
<h3>What is wave?</h3>
A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify it. Transverse and longitudinal are the two main forms.
P waves are sometimes known as primary waves or pressure waves. The earliest waves of an earthquake are known as P waves.
P waves may pass through any medium, including liquids, gases, and solids. P waves can't move particles up and down or side to side.
P wave can travel through liquids. P stand for the primary of pressure wave.
Hence, option D is correct

Answer:
Power is defined as Work / Time
P1 = P2 = W1 / T1 = W2 / T2 W1 and W2 are not necessarily the same Power expended depends on both work input over a unit of time
Answer:
0.152 m
Explanation:
The condition for constructive interference is
d sinθ= mλ (m= 0,1,2,3...)
the slit width
d= 1/N
d= 10^(-3)/520
= 1.92×10^(-6)
The angular spread for the red light is
= 19.97°
The angular spread of blue light is
=14.66°
The distance between the first order red fringe and blue fringe is,
y= y_r- y_b = Ltanθ_r -Ltanθ_b
=1.50( tan19.97°-tan14.66°) = 0.152 m
