Determine the minimum angle at which a roadbedshould be banked
poizon [28]

To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.

The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,

T cos\theta = mg \rightarrow T = \frac{mg}{cos\theta}

Tsin\theta = \frac{mv^2}{r} \rightarrow T = \frac{mv^2/r}{sin\theta}

Equating both equation we have that,

\frac{mv^2}{r} = mgtan\theta

tan\theta = \frac{v^2}{rg}

Rearranging to find the angle we have that,

\theta = tan^{-1} (\frac{v^2}{rg})

Our values are given as,

r = 2.00*10^2m

v = 20m/s

\theta = tan^{-1}(\frac{20^2}{(2*10^{2})(9.8)})

\theta = 11.53 \°

Therefore the minimum angle will be 11.53°

What are the elements of NaCl
Lana71 [14]

The elements in NaCl are Na -sodium and Cl - chlorine

<u>Explanation:</u>

  • sodium chloride (NaCl) is also known as common salt. The molar ratio of NaCl is 1:1 and has the molar mass of 22.99 and 35.45 respectively. The molar mass of NaCl is 58.443 g/mol. It is a odorless and colourless cubic crystal.
  • It has the melting point of 800.7°C and has the boiling point of 1465°C. It has a face centered cubic crystal structure.The elements in NaCl are Na -sodium and Cl - chlorine

                                                        2Na+Cl_{2} → 2NaCl

Is the appearance of a light wave changed as it is aborted?
Sonbull [250]
Light waves are never 'aborted'. 

They can be 'absorbed', and I think that's what you mean. 
It's what happens when light hits something or goes into it,
and never comes out. 

"Absorb" just means "soak up".  When a light wave hits something and
gets soaked up in it, it's gone, and never comes out the other side.

The light wave certainly gets changed ... it no longer exists.

The object that absorbs it also gets changed.  It soaks up the energy
in the light wave, and it has a little more internal energy (heat) than it
had before the light hit it.

If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it will oscillate. If i
Blababa [14]

Explanation:

An object is attached to the spring and then released. It begins to oscillate. If it is displaced a distance 0.125 m from its equilibrium position and released with zero initial speed. The amplitude of a wave is the maximum displacement of the particle. So, its amplitude is 0.125 m.  

After 0.800 seconds, its displacement is found to be a distance 0.125 m on the opposite side. The time period will be, t=2\times 0.8=1.6\ s

We know that the relation between the time period and the time period is given by :

f=\dfrac{1}{t}

f=\dfrac{1}{1.6}

f = 0.625 Hz

So, the frequency of the object is 0.625 Hz. Hence, this is the required solution.

All of the answers have to be dragged into the box
Artyom0805 [142]

Answer:

Acceleration = Passing a car on the highway/Any change in speed or direction/Slowing down to turn at an intersection

Friction = The force that opposes motion/The wheels moving against the road

Newton's first law = An object in motion stays in motion unless acted on by an outside force

Newton's second law = The harder you kick a ball the faster it will travel
