Av Speed = total distance / time time = 32+ 46 / 2.7 = 28 m/sec
Av velocity = total displacement / time total = S / t
S = sqrt( 32^2 +46^2) = 56 m
Av Velocity = 56/ 2,7 = 20.75 m/sec
with angle tan^-1 = 0.7 north west ( about 35 degrees north west)
B) I just took the test and put D but it gave me the wrong answer. It told me it was B.
the answer is A. The aluminum has 0.84 ohms more resistance.
Answer:
0.04225 Nm
Explanation:
N = Force applied = 5 N
= Coefficient of static friction = 0.65
d = Diameter of knob = 1.3 cm
r = Radius of knob = 
Force is given by

When we multiply force and radius we get torque
Torque on thumb

Torque on forefinger

The total torque is given by

The most torque that exerted on the knob is 0.04225 Nm
