What is the period of a pendulum that takes 5 seconds to make a complete back and forth vibration

Physics
1 answer:
dezoksy [38]3 years ago
8 0

Answer:

5s

Explanation:

-A period is the time it takes to make one full back-and-forth swing.

-A period is calculated as the time taken for a complete swing divided by one cycle:

T=t/1c\\\\=5s/1\\\\=5s

Hence, the period of the pendulum is 5s

A 3.00-m rod is pivoted about its left end. A force of 7.80 N is applied perpendicular to the rod at a distance of 1.60 m from t
dalvyx [7]

Answer:

The net torque about the pivot is and the answer is 'c'

c. T_{net}=8.58

Explanation:

T=F*d

The torque is the force apply in a distance so it is the moment so depends on the way to be put it the signs so:

T_1=F_1*d_1

T_1=7.8N*1.6m=12.48N*m

T_2=F_2*d_2

T_2=2.60N**cos(30)*3.0m

T_2= - 3.9 N*m

Now to find the net Torque is the summation of both torques

T_{net}=T_1+T_2

T_{net}=12.48N-3.9N=8.58N

Suppose the coefficient of static friction between the road and the tires on a car is 0.638 and the car has no negative lift. Wh
larisa [96]

Answer:

12.6332454263 m/s

Explanation:

m = Mass of car

v = Velocity of the car

\mu = Coefficient of static friction = 0.638

g = Acceleration due to gravity = 9.81 m/s²

r = Radius of turn = 25.5 m

When the car is on the verge of sliding we have the force equation

\dfrac{mv^2}{r}=\mu mg\\\Rightarrow v=\sqrt{\mu gr}\\\Rightarrow v=\sqrt{0.638\times 9.81\times 25.5}\\\Rightarrow v=12.6332454263\ m/s

The speed of the car that will put it on the verge of sliding is 12.6332454263 m/s
