Answer:
Hey
<em><u>A proton(s), and neutron(s).</u></em>
<em><u>B electron(s).</u></em>
The nucleus (A) contains TWO particles, together they are called nucleons because they are in the nucleus. The two particles in the nucleus are the <u>proton</u> and <u>neutron,</u> they are held together by the nuclear strong force.
Outside of the nucleus, the <u>electron</u> takes up space around the nucleons. It is held in place by the electromagnetic force. It can only be a certain distance from the nucleus as you can see (the two circles around the nucleus). It can not be in between those two distances.

Answer:
Explanation:
Given
height of wall=5.15 m
angle of launch
Launch velocity(u)=52.4 m/s
Time of flight will be sum of time of flight of projectile+time to cover 5.15 m
Time of flight of arrow

Now time require to cover 5.15 m
Here at the time of zero vertical displacement of arrow i.e. when arrow is at the same height as of building then its vertical velocity will change its sign compared to initial vertical velocity.
at zero vertical displacement
Thus time required will be 



total time =
(b)Horizontal distance=Range of arrow(R_1) + horizontal distance in 0.118 s


=263.28+3.546=266.82 m
Answer:
The speed of the automobile after 1.43s is 10 
Explanation:





≅ 10 
Beats.
When two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud - a phenomenon which is called "beating" or producing beats. The beat frequency is equal to the absolute value of the difference in frequency of the two waves.
<em>The correct answer is option</em><em> B.</em> The maximum height that can be reached by the stone is determined as 11.5 m.
<h3>
Maximum height attained by the stone </h3>
The maximum height attained by the stone when it is a 2/3 of its total height is calculated as follows;
v² = u² - 2gh
where;
- v is final velocity at maximum height, v = 0
- u is initial velocity
- g is acceleration due to gravity
0 = u² - 2gh
2gh = u²
h = u²/2g
h = (15²)/(2 x 9.8)
h = 11.48 m
h = 11.5 m
Thus, the maximum height that can be reached by the stone is determined as 11.5 m
