A mass suspended on a spring will exhibit sinusoidal motion when it moves. If the mass on a spring is 85 cm off the ground at it

Answer:

Using equation

y(t)=y0*Cos(wt)

w=2\pi/3

y0=85-41

y(t)=44cos(2\pi/3*t)

Answer:

The equation of motion is y(t)=22sin(\frac{2\pi }{3}t)

Explanation:

The general equation of motion of a SHM motion is given by

y(t)=Asin(\omega t+\phi )

where,

A is the amplitude of the motion

ω is the natural frequency of the system

Since amplitude is defines as the maximum displacement of the object from the mean position we have

2A=85 cm-41 cm\\\\A=\frac{44}{2}cm\\\\\therefore A=22cm

Now the time period is related to the natural angular frequency as

\omega =\frac{2\pi }{T}\\\\\therefore \omega=\frac{2\pi }{3}

Thus the equation of motion becomes

y(t)=22sin(\frac{2\pi }{3}t+\phi )

the initial phase can be assumed to be zero thus the equation becomes

y(t)=22sin(\frac{2\pi }{3}t)

Technician A says that disc brakes are self adjusting and the brake pedal height should not become lower as the disc brake pads
maks197457 [2]

Answer:

c. Both Technicians A and B

Explanation:

Disc brakes are self-adjusting because the pistons in the brakes are much larger in diameter than the ones in the master cylinder. If the brake pistons retracted into their cylinders, it might take several applications of the brake pedal to pump enough fluid into the brake cylinder to engage the brake pads.  The height of the brake pedal is also necessary because if they become lower the disc brake pads will wear, this is why self-adjustment is important and disc brake pads usually have a piece of metal on them called a wear indicator to warn of wearing. Also when disc break pads wear, the fluid level in the master cylinder drops, armed with this knowledge of low master cylinder fluid level one can inspect the disc pads for wear.  Thus both Technicians A and B are correct.

A solid conducting sphere with radius R = 0.390 m carries a net charge of +0.650 nC.
Tom [10]

Answer:

38.5 N/C

Explanation:

The electric field generated by a charged sphere at a point outside the sphere is equivalent to the electric field generated by a single point charge, and it is given by

E=k\frac{Q}{r^2}

where

k=9\cdot 10^9 Nm^2C^{-2} is the Coulomb's constant

Q is the net charge

r is the distance from the centre of the sphere

In this problem, we have

Q=+0.650 nC=0.65\cdot 10^{-9}C

r=0.390 m

Substituting into the equation, we find

E=(9\cdot 10^9)\frac{(0.65\cdot 10^{-9}C)}{(0.390m)^2}=38.5 N/C

Find the vector representing the area of the rectangle with vertices and oriented so that it faces downward. The magnitude of th
sergejj [24]

Answer:

The answer is  "-72 k".

Explanation:

Please find the complete question in the attached file.

Given point:

A=(0,0,0)\\B=(0,8,0)\\C=(9,8,0)\\D=(9,0,0)

\bar{AB} = (0i+8j+0k)-(0i+0j+0k)= 8j\\\\\bar{AC} = (9i+8j+0k)-(0i+0j+0k)= 9i+8j\\\\

Calculating the area:

Area=\left|\begin{array}{ccc}i&j&k\\0&8&0\\9&8&0\end{array}\right|

       =i[8(0)-8(0)]-j[(0-0)]+k[(0-9(8))]\\\\=i[0-0]-j[(0)]+k[(0-72)]\\\\=i[0]-j[(0)]+k[(-72)]\\\\=-72 \ k

Can someone help me find the which direction is north and which is south on this solenoid?
arsen [322]

Explanation:

Now, looking down the solenoid tube determine what direction is the winding. If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole. So, to summarize the magnetic south pole is always clockwise in relation to the positive wire.
