Answer:

Explanation:

The formula for kinetic energy to be used here is 1/2mv².

If the first particle is "particle a" and the second particle is "particle n"; there kinetic energies (K.E) will be

K.Eₐ = 1/2.m2v² = mv²

K.Eₙ = 1/2.2mv² = mv²

From the above, <u>it can be said that there kinetic energies are the same</u>.

NOTE that the m and v used in the question means mass and velocity respectively.

How much water is stored in groundwater lakes rivers soil and streams
Ne4ueva [31]

Answer:

Explanation:

Most of this water is locked up in ice, and another 20.9% is found in lakes. Rivers make up 0.49% of surface freshwater. Although rivers account for only a small amount of freshwater, this is where humans get a large portion of their water from.

bogdanovich [222]

Answer:

speed is 81.03 mph

direction is N 3.58 W

Explanation:

given data

travel north = 70 mph

Stream current = 12 mph

direction = S 25° E

result due north = 70 mph

to find out

speed and direction

solution

we will get component of resultant  that is

v cosθ  and v sinθ

so

( 12cos295 , 12 sin295 )    at ( 0, 70)

as that we can say

v sinθ + 12sin295 = 70      ....................1

v cosθ + 12 cos295  = 0     ......................2

so

vcosθ  = -5.0714

vsinθ = 80.8756

now by ratio

cosθ /sinθ  = -5.0714/ 80.8756

cot θ = -0.0627

θ = 93.58

so direction is N 3.58 W

and

we know

vcosθ  = - 12cos295

v = - 12cos295 / cos(93.58)

v = 81.03 mph

so speed is 81.03 mph
