Answer:
Chemical energy is converted to thermal energy and electrical energy.
Explanation:
Explanation:
I = 120/30=2A
Voltage across R3= current × resistance
= 2A × 15 ohm = 30 volt
It is is real because potential energy is stored inside gravitational energy.
The answer is C. Sesamoid bones
Answer:
Fc = 1.7x10^-4 N
Explanation:
Convert everything to proper units:
m = 25mg = 2.5x10^-5 kg
r = 17.6cm = 0.176m
v = 110cm/s = 1.1m/s
the formula for centripetal force is Fc = mv^2 / r
Plug everything and solve for Fc;
fc = (2.5x10^-5)(1.1^2) / 0.176
Fc = 1.7x10^-4 N
