Spring lies on a horizontal table, and the left end of the spring is attached to a wall. the other end is connected to a box. th

e box is pulled to the right, stretching the spring. static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. the mass of the box is 0.80 kg, and the spring has a spring constant of 59 n/m. the coefficient of static friction between the box and the table on which it rests is s 0.74. how far can the spring be stretched from its unstrained position without the box moving when it is released?

I cant solve this problem, and our teacher said that this would be in the test we'll have tomorrow, can someone help me?
Ad libitum [116K]

Answer:

d = 11.1 m

Explanation:

Since the inclined plane is frictionless, this is just a simple application of the conservation law of energy:

\frac{1}{2} m {v}^{2}  = mgh

Let d be the displacement along the inclined plane. Note that the height h in terms of d and the angle is as follows:

\sin(15)  =  \frac{h}{d}  \\ or \: h = d \sin(15)

Plugging this into the energy conservation equation and cancelling m, we get

{v}^{2}  = 2gd \sin(15)

Solving for d,

d =  \frac{ {v}^{2} }{2g \sin(15) }  =  \frac{ {(7.5 \:  \frac{m}{s}) }^{2} }{2(9.8 \:  \frac{m}{ {s}^{2} })(0.259)}   \\ = 11.1 \: m

How many orders of magnitude (powers of ten) is the distance to the moon greater than the distance across the Atlantic ocean?
kupik [55]

Answer:

The distance to the moon greater than the distance across the Atlantic ocean by an order of 1.

Explanation:

We have the average distance across the Atlantic ocean, d_i=3700\ mi

the average distance to the moon, d_m=238,900\ mi

The factor by which the distance to moon is greater than the width of Atlantic ocean:

f=\frac{d_m}{d_i}

f=\frac{238,900}{3700}

f=64.57

i.e.

the distance to the moon greater than the distance across the Atlantic ocean by an order of 1.

Why sound are more audible at night then in a day ? (please hope answer will not be too long)​
mojhsa [17]

<em><u>Answer:</u></em>

You can only hear it at night. The reason for this upward diversion of sound in the daytime versus the downward diversion at night is the strong dependency of the speed of sound in the atmosphere on temperature. The atmosphere acts like a lens that focuses sound energy upwards during the day, but keeps it at ground level during the night.

<em><u>Or</u></em>

<em><u>During the day, the sound bends away from the ground; during the night, it bends towards the ground. Hence at night you have additional "sound" reaching you, making it louder.</u></em><em><u> </u></em>

This is the Answer for your question :3

I hope you are having a great day ❤️❤️❤️❤️❤️

A wire with a linear mass density of 1.17 g/cm moves at a constant speed on a horizontal surface and the coefficient of kinetic
stira [4]

Answer:

The value is B  =  0.2312 \  T

The direction is into the surface

Explanation:

From the question we are told that

   The mass density is  \mu =\frac{m}{L}  = 1.17 \ g/cm =0.117 kg/m

   The coefficient of kinetic friction is  \mu_k  =  0.250

   The current the wire carries is  I =  1.24 \  A

Generally the magnetic force acting on the wire is mathematically represented as

         F_F   = F_B

Here   F_F is the frictional  force which is mathematically represented as

      F_F =  \mu_k *  m *  g

While F_B  is the magnetic force which is mathematically represented as

       F_B  = BILsin(\theta )

Here \theta =90^o is the angle between the direction of the force and that of the current

So

      F_B  = BIL

So

      BIL  =  \mu_k * m * g

=>   B  =  \mu_k *  \frac{m}{L} * [\frac{g}{I} ]

=>   B  =  0.25 *  0.117  * [\frac{9.8}{1.24} ]

=>   B  =  0.2312 \  T

Apply the right hand curling rule , the thumb pointing towards that direction of the current we see that the direction of the magnetic field is into the surface as shown on the first uploaded image
