Who serves as the presiding officer of the Senate?

The
of the United States serves as the presiding officer of the Senate.
At present,
is the president of the Senate.

Explanation:
Acceleration is change in velocity over change in time.
a = Δv / Δt
a = (10 m/s − 5 m/s) / 4 s
a = 1.25 m/s²
Work = force × distance
First, find the distance traveled.
v² = v₀² + 2aΔx
(10 m/s)² = (5 m/s)² + 2 (1.25 m/s²) Δx
Δx = 30 m
Now find the work:
W = (600 kg × 1.25 m/s²) (30 m)
W = 22,500 J
Alternative, work = change in energy.
W = ΔKE
W = ½ mv² − ½ mv₀²
W = ½ m (v² − v₀²)
W = ½ (600 kg) ((10 m/s)² − (5 m/s)²)
W = 22,500 J

Answer:
longest length is 13304.05 m
Explanation:
given data
diameter = 25 mm
so radius r = 12.5 ×
m
density = 5000 kg/m³
tension = 320000 N
to find out
longest length of of this rope
solution
we know that here tension is express as
T = m × g
and m is mass and g is acceleration due to gravity
here mass = density × volume
and volume = π×r²×l
here r is radius and l is length
so T = density c volume × g
put here value
320000 = 5000 × π×12.5² ×
× l × 9.8
solve it we get length l
l = 13304.05
so longest length is 13304.05 m
