Answer:

Potential

Explanation:

The most accurate term is Electrostatic potential energy

It is denoted as UC

It's named like this because the force between charges or electrons is called electrostatic force .

What is the pair of vectors if summed , would create of equilibrium (a resultant of 0i + 0j) ?

bogdanovich [222]

<u>ANY</u> pair of vectors can produce that resultant, as long as ...

If one of the vectors is V₁ = A i + B j . . . . . . where 'A' and 'B' are <u>any</u> two numbers,

then the other one is V₂ = -A i - B j

Answer:

A) Option 1 is the correct answer.

B) Option 4 is the correct answer.

Explanation:

A) Weight of liquid = 7 N

Volume of liquid = 1 L = 0.001 m³

Specific weight = $\frac{7}{0.001}=7000N/m^3$

Density = $\frac{7000}{9.81}=713.5kg/m^3$

Specific gravity = $\frac{713.5}{1000}=0.7135$

Option 1 is the correct answer.

B) The Stokes(St) is the cgs physical unit for kinematic viscosity, named after George Gabriel Stokes.

We have

1 St = 10⁻⁴ m²/s

Option 4 is the correct answer.

A manufacturer provides a warranty against failure of a carbon steel product within the first 30 days after sale. Out of 1000 so

hodyreva [135]

Answer:A) Risk(R)= $1000

B) There is justification for spending an additional cost of $100 to prevent a corrosion whose consequence in monetary terms is $1000

Explanation:R= Risk,

P=Probability of failure

C= Consequence of failure

Mathematically, R=P ×C

10 out of 1000 carbon-steal products failed

Probability of failure= 10/1000 =0.01

The consequence of failure by corrosion given in monetary term =$100,000

Risk of failure = 0.01 × $100,000

R=$1000

A violin string is 45.0 cm long and has a mass of 0.242 g. When tightened on the neck of the violin, the distance between the pi

stiks02 [169]

Answer:

The tension is 75.22 Newtons

Explanation:

The velocity of a wave on a rope is:

$v=\sqrt{\frac{TL}{M}}$ (1)

With T the tension, L the length of the string and M its mass.

Another more general expression for the velocity of a wave is the product of the wavelength (λ) and the frequency (f) of the wave:

$v= \lambda f$ (2)

We can equate expression (1) and (2):

$\sqrt{\frac{TL}{M}}$ = $\lambda f$

Solving for T

$T= \frac{M(\lambda f)^2}{L}$ (3)

For this expression we already know M, f, and L. And indirectly we already know λ too. On a string fixed at its extremes we have standing waves ant the equation of the wavelength in function the number of the harmonic $N_{harmonic}$ is:

$\lambda_{harmonic}=\frac{2l}{N_{harmonic}}$

It's is important to note that in our case L the length of the string is different from l the distance between the pin and fret to produce a Concert A, so for the first harmonic:

$\lambda_{1}=\frac{2(0.425m)}{1}=0.85 m$

We can now find T on (3) using all the values we have:

$T= \frac{2.42\times10^{-3}(0.85* 440)^2}{0.45}$

$T=75.22 N$
