Answer:
0.859375c
31.03 seconds
Explanation:
v' = Velocity of my ship = 0.4 c
u = Velocity of rocket = 0.7 c
c = Speed of light = 
s = Distance between my ship and enemy ship = 
Relativistic addition of speed is given by
The speed of the missile is 0.859375c
Time is given by
It will take 31.03 seconds to reach me.
Answer:
0.003181 radians
0.003005 radians
Explanation:
Number of slits = 140 /cm
λ = Wavelength = 434 nm = 434×10⁻⁹ m
m = 3 Third order spectrum
Space between slits
Now,
0.003181 radians
When λ = 410 nm = 410×10⁻⁹ m
0.003005 radians
Answer:
c. 65
Explanation:
The output is 65.
An array of length 10 is created first. Then, the first for-loop fill the array with different values; The array element now become: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The array element are generated using the equation a[i] = i + 2; so when i is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. i must be less than the array length (10).
a[0] = 0 + 2 = 2
a[1] = 1 + 2 = 3
a[2] = 2 + 2 = 4
a[3] = 3 + 2 = 5
a[4] = 4 + 2 = 6
a[5] = 5 + 2 = 7
a[6] = 6 + 2 = 8
a[7] = 7 + 2 = 9
a[8] = 8 + 2 = 10
a[9] = 9 + 2 = 11
result variable is declared and initialized to 0.
The second for-loop goes through the array and add individual element to result.
Answer: 6s
Explanation:
Vs=32m/s speed at beginning of slowing down
Vf=0m/s stop speed
a= -6 m/s² acceleration
----------------
Use equation for acceleration :
a=(Vf-Vs)/t
a*t=Vf-Vs
t=(Vf-Vs)/a
t=(0-36)/-6
t=-36/-6
t=6 s
Answer:
Objective Lenses: Usually you find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers, when coupled with a 10x (most common) eyepiece lens, total magnification is 40x (4x times 10x) 100x, 400x and 1000x
Explanation:
Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power and typically oil immersion objectives, respectively
