Answer:
Explanation:
Given
Diameter of the rod
length of rod is
Resistivity of silicon is
cross-section of the rod
Resistance of rod is R
Current is given by
Answer:
Explanation:
A
35 N Small Dog <=======BONE=========> Bigger Dog 42 N
B
Fnet = Large Dog - small dog The forces are subtracted because they are acting in opposite Directions.
Fnet = 42 - 35
Fnet = 7 N
C
m = 2.5 kg
F = 7 N
a = ?
F = m * a
7 = 2.5 a
a = 7 / 2.5
a = 2.8 m/s^2
We could use the formula for the Power supply in order to find the wattage capacity and it would be:
P = V²/R or P = V * I
Hope this helps!
