Eq-35 how many fire extinguishers are required aboard an 18-foot powerboat with installed fuel tank(s)?

1 answer:

5 0

There is at least one USCG-endorsed Class B-1 for the fire extinguisher that is required on any powerboat unless it is with the accompanying special case:
1. speedboats under 26 feet long,
2. moved by detachable engines and
3. not conveying travelers for procuring, require not convey such compact fire dousers if
4. the development of such speedboats won't allow the entanglement of touchy or combustible gasses or vapors

A singly charged 7Li ion has a mass of 1.16 10-26 kg. It is accelerated through a potential difference of 523 V and subsequently

mel-nik [20]

Answer:

$R=0.023m$

Explanation:

From the question we are told that:

Mass $m=1.16*10^{-26}$

Potential difference $V=523V$

Magnitude $m=0.370 T$

Generally the equation for Velocity is mathematically given by

$\frac{1}{2}mv^2=ev$

$v=\frac{2ev}{m}$

$v=\frac{2*1.6*10^{-19}*542}{1.16*10^{-26}}$

$v=12.22*10^4m/s$

Generally the equation for Force is mathematically given by

$F=qvBsin \theta$

Where

$qVB=m\frac{v^2}{R}$

$F=m\frac{v^2}{R}sin\theta$

Therefore

$R=\frac{mv}{qB sin \theta}$

$R=\frac{1.6*10^{-26}*12.2*10^{4}}{1.60*10^{-19}*0.394 sin 90}$

$R=0.023m$

The magnitude E of an electric field depends on the radial distance r according to E = A/r4, where A is a constant with unit vol

Lesechka [4]

Answer:

$\Delta V = 0.053 A$

Explanation:

Electric field in a given region is given by equation

$E = \frac{A}{r^4}$

as we know the relation between electric field and potential difference is given as

$\Delta V = -\int E. dr$

so here we have

$\Delta V = - \int (\frac{A}{r^4}) .dr$

$\Delta V = \frac{A}{3r_1^3} - \frac{A}{3r_2^3}$

here we know that

$r_1 = 1.71 m$ and $r_2 = 2.89 m$

so we will have

$\Delta V = \frac{A}{3}(\frac{1}{1.71^3} - \frac{1}{2.89^3})$

so we will have

$\Delta V = 0.053 A$

D. A beam balance does not measure mass; it measures weight. The gravitational force of attraction between the earth and an object depend on the mass of the object. ... The beam balance measures the force F exerted by the mass on the beam balance
