Answer:
<em>t=14.96 sec</em>
Explanation:
<u>Diagonal Launch
</u>
It's a physical event that happens where an object is thrown in free air (no friction) forming an angle with the horizontal reference. The object then describes a path called a parabola.
The object will reach its maximum height and then return to the height from which it was launched. The equation for the height is
:
Where vo is the initial speed, is the angle, t is the time and g is the acceleration of gravity
.
In this problem we'll assume the arrow was launched from the ground level (won't consider the archer's height). Thus , and:
The value of y is zero twice: when t=0 (at launching time) and in t= when it goes back to the ground. We need to find that time by making
Dividing by
Then we find the total flight time as
Placing the electromagnetic radiation in order from the lowest energy to the highest energy : ( 2 ) C,A,B
<h3>Electromagnetic spectrum </h3>
In the electromagnetic spectrum the electromagnetic radiation with the shorter wavelength possess a higher energy while the electromagnetic radiation with a longer wavelength possess the lower energy.
The electromagnetic radiation as listed in the question with the longest wavelength is the radio waves therefore it possess the lowest energy while the radiation with the shortest wavelength is the gamma rays therefore it possess the highest energy.
Hence we can conclude that Placing the electromagnetic radiation in order from the lowest energy to the highest energy : ( 2 ) C,A,B

<span>The mass of potassium is 39. This is obtained by adding the 19 protons and 20 neutrons found inside the nucleus</span>
Initial launch velocity, u = 0
Acceleration, a = 300 m/s²
Duration, t = 8.0 s
The distance traveled is
h = ut + (1/2)*a*t²
= (0 m/s)*(8 s) + 0.5*(300 m/s²)*(8 s)²
= 9600 m
Answer: 9600 m
Answer: D just took the test
