Complete Question
A proton is located at <3 x 10^{-10}, -5*10^{-10} , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton
Answer:
The vector position is 
Explanation:
From the question we are told that
The position of the proton is 
Generally the vector location of the proton is mathematically represented as
So substituting values
Answer:
the answer is b
Explanation:
because you multiply speed times wavelength
A jug would hold more volume than a mug
Answer:
runway use is 3307.8 feet
Explanation:
given data
velocity = 140 kts = 140 × 0.5144 m/s = 72.016 m/s
time = 28 seconds
weight = 28000 lbs
to find out
How many feet of runway was used
solution
we will use here first equation of motion for find acceleration
v = u + at ..............1
here v is velocity given and u is initial velocity that is 0 and a is acceleration and t is time
put here value in equation 1
72.016 = 0 + a(28)
a = 2.572 m/s²
and
now apply third equation of motion
s = ut + 0.5×a×t² .......................2
here s is distance and u is initial speed and t is time and a is acceleration
put here all value in equation 2
s = 0 + 0.5×2.572×28²
s = 1008.24 m = 3307.8 ft
so runway use is 3307.8 feet
In this item, we are asked to determine the correct definition for the terms. It is unfortunate that they meanings to which we could match them are not given. With that, the answers written here are the well-researched ones.
Solution --> This type of erosion happens when the components found in the rocks (i.e. limestone) are dissolved through the acid components of acid rain.
Abrasion --> This is a process by which the rocks that are eroded to the riverbanks wear down other components of the bed.
Saltation --> This process involves the movement of the particles through a series of bounces that are short and are along the surface of the ground. This results to dislodging the other particles.
