Sample Response: The technology being described is fiber optics. Since they are small and flexible, they enable doctors to see areas that they might otherwise be unable to see without surgery.
Answer:
Two marbles are launched at t = 0 in the experiment illustrated in the figure below. Marble 1 is launched horizontally with a speed of 4.20 m/s from a height h = 0.950 m. Marble 2 is launched from ground level with a speed of 5.94 m/s at an angle above the horizontal. (a) Where would the marbles collide in the absence of gravity? Give the x and y coordinates of the collision point. (b) Where do the marbles collide given that gravity produces a downward acceleration of g = 9.81 m/s2? Give the x and y coordinates.

i want the answer i don't know
Answer:
A. Create radioactive waste i believe
Explanation:
If an object is projected with vertical speed given as

now the time of flight of the object that time in which it comes back on ground

now here we will have


now the range of projectile is given as


now here we know that


now the range is given as


now in order to have maximum range we can say


so we will have

so now we can say

so both speed must be same to have maximum horizontal range
Answer:
D. 0.60 um
Explanation:
Given the following data;
Frequency = 5.0x10^14 Hz
Speed = 3 x 10^8 m/s
To find the wavelength;
Wavelength = speed/frequency
Substituting into the equation, we have
Wavelength = 3 x 10^8/5.0x10^14
Wavelength = 6 × 10^7m
But 1 meter (m) = 1000000 micrometer (um)
6 × 10^7 meter = 0.6 micrometer.
