A car battery has a rating of 170 ampere-hours. This rating is one indication of the total charge that the battery can provide t
Pavlova-9 [17]

Answer:

612000 C

Explanation:

Current, I, is given as the rate of flow of charge, that is:

I = Δq / Δt

where q = electric charge

t = time taken

This implies that:

Δq = I * Δt

The battery rating is 170 Ampere-hours, therefore:

Δq = 170 * 1 hour

But 1 hour = 3600 seconds;

=> Δq = 170 * 3600 = 612000 C

The total charge that the battery can provide is 612000 C.

Which one of the following statements is true? Explain.
Makovka662 [10]

Answer:

All the given option is false.

Explanation:

A)

This is not true for all the materials like composite because the Poisson ratio for composite material can be negative that is why positive tensile stress may produce positive lateral strain.

B)

This is not true for all the material because the Poisson ratio for some material can be positive  that is why positive tensile stress may produce negative lateral strain.

C)

The explanation is same as option A.

D)

This is not true for all the materials ,It is valid only up to elastic limit .After the elastic limit the strain and stress does not follow linear path.

E)

This is not true for all the materials because some materials like composite is having negative value of Young's modulus.

Therefore all the given option is false.

The airport has a new plane that can go from 0 miles per hour to 100 miles per hour in 10 seconds. What is being described about
Nonamiya [84]
<h3 />

<h2 /><h2 /><h2>Acceleration : </h2>

Acceleration is a vector quantity that is defined as ❝ rate of change in velocity ❞

And as per the question, the plane can go from 0 miles to 100 miles/hour in 10 seconds that shows rate of change in its velocity. that is :

from 0 miles/hour to 100 miles/hour. hence Acceleration is the quantity being described about the new plane.

  • \qquad \sf  \dashrightarrow \: a =  \dfrac{v - u}{t}

[ v = final velocity, u = initial velocity, t = time ]

  • \qquad \sf  \dashrightarrow \: a =  \dfrac{100 - 0}{10}

  • \qquad \sf  \dashrightarrow \: a =  \dfrac{100}{10}

  • \qquad \sf  \dashrightarrow \: a = 10 \:

So, the Acceleration of the new plane is 10 miles/hour²
