Answer:
Capacitance = ( 4π×∈×r×R ) / (R-r)
energy store = ( 4π×∈×r×R )×V² / (R-r)
Explanation:
given data
radius = r
radius = R
r < R
to find out
capacitance and how much energy store
solution
we consider here r is inner radius and R is outer radius
so now apply capacitance C formula that is
C = Q/V .................1
here Q is charge and V is voltage
we know capacitance have equal and opposite charge so
V =
here E = Q / 4π∈k²
so
V = Q / 4π∈
V = Q / 4π∈ × ( 1/r - 1/R )
V = Q(R-r) / ( 4π×∈×r×R )
so from equation 1
C = Q/V
Capacitance = ( 4π×∈×r×R ) / (R-r)
and
energy store is 1/2×C×V²
energy store = ( 4π×∈×r×R )×V² / (R-r)

Answer:
The coefficient of static friction between the ground and the soles of a runner’s shoes is 0.98. What is the maximum speed in which the runner can accelerate without slipping if they have a mass of 73 kg?
Explanation:
Thermal energy is not in the process of being transferred it is not in transit but remains as part of the internal energy of the system heat on the other hand is energy in transit energy is the process of being transferred from a hotter system towards another colder system
