The answer is C. Near the cold front
Answer with Explanation:
We are given that
Diameter=d=22.6 cm
Mass,m=426 g=
1 kg=1000 g
Radius,r=
1m=100 cm
Height,h=5m

a.By law of conservation of energy






Where 
b.Rotational kinetic energy=
Rotational kinetic energy=8.35 J
Answer: 6117.58 J
Explanation:
We know that W=Fd*cos(theta) where theta is the angle between the displacement and the force.
In this case, we are given that F=225 N, d=30 m, and theta=25 degrees.
Plugging all this in we get
W=225*30*cos(25)=6117.58 J
A run though an open field during a thunderstorm is the answer
Answer:
ω2 = 216.47 rad/s
Explanation:
given data
radius r1 = 460 mm
radius r2 = 46 mm
ω = 32k rad/s
solution
we know here that power generated by roller that is
power = T. ω ..............1
power = F × r × ω
and this force of roller on cylinder is equal and opposite force apply by roller
so power transfer equal in every cylinder so
( F × r1 × ω1) ÷ 2 = ( F × r2 × ω2 ) ÷ 2 ................2
so
ω2 =
ω2 = 216.47
