Answer:
8.25 x 10^-3 V/m
Explanation:
Resistivity, ρ = 2.44 x 10^-8 Ohm m, Diameter = 1.8 mm
radius, r = 0.9 mm = 0.9 x 10^-3 m, l = 40 cm = 0.4 m, i = 860 mA = 0.86 A,
Let V be the potential difference and E be the electric field.
Use the formula for resistance
R = ρ l / A
R = (2.44 x 10^-8 x 0.4) / ( 3.14 x 0.9 x 0.9 x 10^-6)
R = 3.84 x 10^-3 ohm
According to Ohm's law
V = i x R
V = 0.860 x 3.84 x 10^-3 Volt = 3.3 x 10^-3 Volt
E = V / l = 3.3 x 10^-3 / 0.4 = 8.25 x 10^-3 V/m
C is your answer im pretty sure
Sensors in the muscles and joints send messages back through peripheral nerves to tell the cerebellum and other parts of the brain where and how the arm or leg is moving and what position it's in
Answer:
Time period becomes one third
Explanation:
Time period is the reciprocal of frequency
so if frequency is tripled period will be one third.
The nuclear forces are very short range whereas the electromagnetic force has a long range.
