In physics, why would an equation like y=mx+b be plotted as a straight line rather than as a parabola, as is done in math?
notka56 [123]

Answer:

Explanation:

In Both Physics and Math

y=mx+b is plotted as straight line where

m=slope of line

b=intercept on Y-axis

whereas Equation of parabola is something like this

y^2=4ax

or

x^2=4ay

Math is a tool to solve Physics problems so equations are same in math and physics

a force of 35N is exerted over a cylinder with an area of 5m^2. What pressure,in pascals, will be transmitted in the hydraulic s
gayaneshka [121]

Answer:

<h3>The answer is 7 Pa</h3>

Explanation:

The pressure transmitted in the hydraulic system can be found by using the formula

p =  \frac{f}{a}  \\

f is the force

a is the area

From the question we have

p =  \frac{35}{5}  \\

We have the final answer as

<h3>7 Pa</h3>

Hope this helps you

A transformer connected to a 120-v(rms) at line is to supply 13,000V(rms) for a neon sign.
lyudmila [28]

Answer:

(a) 108

(b) 110.500 kW

(c) 920.84 A

Solution:

As per the question:

Voltage at primary, V_{p} = 120\ V          (rms voltage)

Voltage at secondary, V_{s} = 13000\ V  (rms voltage)

Current in the secondary, I_{s} = 8.50\ mA  

Now,

(a) The ratio of secondary to primary turns is given by the relation:

\frac{N_{s}}{N_{p}} = \frac{V_{s}}{V_{s}}

where

N_{p} = No. of turns in primary

N_{s} = No. of turns in secondary

\frac{N_{s}}{N_{p}} = \frac{13000}{120} ≈ 108

(b) The power supplied to the line is given by:

Power, P = V_{s}I_{s} = 13000\times 8.50 = 110.500\ kW

(c) The current rating that the fuse should have is given by:

\frac{V_{s}}{V_{p}} = \frac{I_{p}}{I_{s}}

\frac{13000}{120} = \frac{I_{p}}{8.50}

I_{p} = \frac{13000}{120}\times 8.50 = 920.84\ A

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Nostrana [21]

Don't look now, but the question GIVES you the formula to use, and it GIVES you the numbers to plug into the formula.

The formula to use to find the distance covered by the sound is

<em>Speed = (distance) / (time)</em>

They also give you:

speed = 330 m/s

time = 0.40 second

Stuff the numbers into the formula:

330 m/s = (Distance) / (0.40 second)

Multiply each side by (0.40 second), and you get:

(330 m/s) / (0.4 second) = Distance

<em>825 meters = Distance</em>
