A(n) 93 kg clock initially at rest on a horizontal floor requires a(n) 617 N horizontal force to set it in motion. After the clo

Viefleur [7K]

Answer:

$\mu_s = 0.676$

Explanation:

As we know that the force required to move the clock from rest position must be equal to the maximum limiting friction

So we will have

$F = F_f$

now we know that

$F_f = \mu_s Mg$

here we will have

$F = 617 N$

$m = 93 kg$

now from above formula we will have

$617 = \mu_s (93)(9.81)$

$\mu_s = 0.676$

A certain fm radio station broadcasts electromagnetic waves at a frequency of 125000 hertz. these radio waves travel at a speed

faltersainse [42]

Speed = frequency x wavelength
300,000,000 = 125000 x wavelength
wavelength = 125000/300,000,000 =4.16667x10^-4 meters

A child on a bridge throws a rock straight down to the water below. The point where the child released the rock is 82 m above th

eimsori [14]

Answer:

40 m/s

Explanation:

given,

height of the fall, h = 82 m

time taken to fall, t = 1.3 s

rock velocity, v = ?

acceleration due to gravity, g = 9.8 m/s²

rock is released initial velocity, u = 0 m/s

using equation of motion

v² = u² + 2 a s

v² = 0 + 2 x 9.8 x 82

v² = 1607.2

v = 40 m/s

hence, rock's velocity is equal to 40 m/s
