<span>Ocean currents act much like a conveyer belt,
transporting warm water and precipitation from the equator toward the
poles and cold water from the poles back to the tropics. Thus, currents
regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.</span>
O2 refers to two oxygen atoms bonded together, while 2 O refers to two oxygen atoms that are not bonded to each other. They both have two oxygen atoms, but in O2, the oxygen atoms are bonded, while in 2O, the atoms are not.

Answer:
P = 1097 Watt
Explanation:
given,
length of stairs, L = 130 m
inclination with horizontal,θ = 30°
mass of the football player = 105 Kg
time = 61 s
we know,

Work = change in Potential energy
h = L sin 30°
h = 130 x 0.5
h = 65 m
W = m g h
W = 105 x 9.8 x 65
W = 66885 J
now,

P = 1097 Watt
hence, the power output on the way is 1097 W
Answer:
time is 5.973826 sec
Explanation:
Given data
diameter D = 6.0 mm 6×
m
separated d = 0.010 m
distance (dis) 185 m
speed s = 16 m/s
wavelength = 550 nm = 550
m
to find out
How much time passes
solution
we know that for resolution we use Rayleigh's Criterion i.e
θ = 1.22 wavelength / diameter = separated / distance 1
we calculate distance 1 by put value wavelength, diameter and separated
distance 1 = diameter × separated / 1.22 wavelength
distance 1 = 6×
× 0.010 / 1.22 × 550 × 
distance 1 = 89.418778
so time will be i.e = distance (dis) - distance 1 / speed
time = ( 185 - 89.418778) / 16
time = 5.973826 sec
time is 5.973826 sec
