Answer:
E = ρ ( R1²) / 2 ∈o R
Explanation:
Given data
two cylinders are parallel
distance = d
radial distance = R
d < (R2−R1)
to find out
Express answer in terms of the variables ρE, R1, R2, R3, d, R, and constants
solution
we have two parallel cylinders
so area is 2
R × l
and we apply here gauss law that is
EA = Q(enclosed) / ∈o ......1
so first we find Q(enclosed) = ρ Volume
Q(enclosed) = ρ (
R1² × l )
so put all value in equation 1
we get
EA = Q(enclosed) / ∈o
E(2
R × l) = ρ (
R1² × l ) / ∈o
so
E = ρ ( R1²) / 2 ∈o R
Answer:The locomotor skills include: walking, running, skipping, galloping, hopping, jumping, sliding, walking backwards, and leaping. Students are learning these skills at it could take lots of practice to develop the skills necessary to complete all of the locomotor skills.

Answer:
Explanation:
Reaction force of inclined surface
R = mgcos30
=60 x 9.8 x .866
= 509 N
Force of kinetic friction
= .12 x 509
= 61.08 N
b )
net force downwards = mgsinθ - μmgcosθ
acceleration = g sinθ - μgcosθ
9.8 sin30 - .12 x 9.8 x cos30
= 4.9 - 1.018
a= 3.88 m /s²
c )
v² = 2as
= 2 x 3.88 x 20
v = 12.46 m /s
