It was <em>(1/2) (Net force on the cart) m/s²) </em>.
Answer:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Answer:
As the speed is constant
Distance = Speed x Time
45min = (45/60)hrs = 0.75hrs
Distance = 75 x 0.75 = 56.25km
Explanation:
Answer:
+14.0 m/s
Explanation:
we have mV + Mv = mU + Mu we solve for U = (mV + Mv - Mu)/m = (328*19.1 + 790*13 - 790*15.1)/328 = 14. Answer
Answer:
4.22 mm
Explanation:
E = Young’s modulus for steel = 210 GPa (generally)
= Change in length = 3 mm
= Original length = 4 m
A = Area of cable
g = Acceleration due to gravity = 9.81 m/s²
r = Radius of cable
d = Diameter = 2r
m = Mass of chandelier = 226 kg
= Longitudinal strain =
Uniaxial stress is given by
The diameter of the cable is 4.22 mm
