If one were to stack thick fabric fabric on top of one another, then push the opposite ends towards one another, resulting and b

Answer:

The answer is "folding".

Explanation:

It is a physical reconfiguring of the process, which gives a fabric a softer, lightweight shape. It is achieved in a far less simple space to carry or store products.  

  • When one places effect sizes on each other, instead move the different ends to each other and fold and roll it, its linear function of Folding would be illustrated.  
  • Except in geography, the piling process naturally creates space to makes the surface clearer and lighter.

A conductor carrying 14.7 amps of current is directed along the positive x-axis and perpendicular to a uniform magnetic field. A
Gnoma [55]

Explanation:

It is given that,

Current carried in the conductor, I = 14.7 A (+x axis)

The magnetic force per unit length on the conductor, \dfrac{F}{L}=0.125\ N/m (-y axis)

The magnetic force is given by :

F=ILBsin\theta

\theta=90

F=ILB

B=\dfrac{F}{IL}

B=\dfrac{0.125}{14.7}  

B = 0.0085 T

According to right hand rule, the direction of magnetic force can be calculated. So, the direction of magnetic field is along +z axis. Hence, this is the required solution.

An object has a mass of 15 kg and is accelerating to the right at 16.3 m/s2. The free-body diagram shows the horizontal forces a
marshall27 [118]
Refer to the free body diagram shown melow.

F =  applied force
R =  frictional force
m = 15 kg, the mass of the object

The acceleration (to the right) is 16.3 m/s², therefore
F - R = (15 kg)*(16.3 m/s²) = 244.5 N

The normal reaction is
N = mg = (15 kg)*(9.8 m/s²)  = 147 N
The frictional force is
R = μN = 147μ N,  where μ =  coefficient of kinetic friction.

Let us check possible answers:
If R = 5.5 N, then μ = 5.5/147 = 0.0374 (very likely)
If R = 15 N, then μ = 15/147 = 0.102 (possible)
If R = 244.5 N,   (Highly unlikely, exceed mg)
If R = 494.5 N, (highly unlikely, exceeds mg)

Answer:
The most reasonable answer is R = 5.5 N

A sun-like star is barely visible to naked-eye observers on earth when it is a distance of 7.0 light years, or 6.6 * 1016 m, awa
igomit [66]

Answer:

At a distance of 1376.49 candle emits 0.2 watt power

Explanation:

Distance between Sun and earth 6.6\times 10^{16}m

Sun emits a power of P=3.8\times 10^{26}watt

Power emitted by candle = 0.20 watt

We know that brightness is given by

B=\frac{P}{4\pi d^2}

So \frac{3.8\times 10^{26}}{4\pi (6\times 10^{16})^2}=\frac{0.20}{4\pi d^2}

3.8\times 10^{26}d^2=7.2\times 10^{32}

d^2=1.89\times 10^6

d=1376.49m

So at a distance of 1376.49 candle emits 0.2 watt power

Why is a force required to keep a body moving with a uniform speed in a circular motion?
andrew-mc [135]
Because if there's no force on the object, then it just moves in a straight line.
