Answer:

Explanation:

Why are students in Hawaii required to learn the history of debate surrounding the writing of the first 10 amendments to the constitution? They were not a member of the United States at the time?

The reason they have to learn anything they can about the constitution is because they are governed by it (just as you are).

The reason you have to learn about the Earth's Systems is because currently there is a huge debate about global warming. The problem is that we are not sure what the solution might be and we've already spent billions on reducing our effect on the environment. Billions means your tax dollars (many) or that of your parents. Many scientists are not sure we should be doing anything.

You will enter the work force one day and if you get a good job, you will be taxed. You should never be unaware of what your tax dollars are spent on.

If you wish to take a picture of a bullet traveling at 500 m/s, then a very brief flash of light produced by an RC discharge thr

Agata [3.3K]

Answer:

Resistance in the flash tube, $R=3.97\times 10^{-3}\ \Omega$

Explanation:

It is given that,

Speed of the bullet, v = 500 m/s

Distance between one RC constant, d = 1 mm = 0.001 m

Capacitance, $C=503\ \mu F=503\times 10^{-6}\ F$

The time constant of RC circuit is given by :

$\tau=RC$

R is the resistance in the flash tube

$R=\dfrac{\tau}{C}$ ..........(1)

Speed of the bullet is given by total distance divided by total time taken as :

$v=\dfrac{d}{\tau}$

$\tau=\dfrac{d}{v}$

$\tau=\dfrac{0.001}{500}$

$\tau=0.000002\ s$

Equation (1) becomes :

$R=\dfrac{0.000002}{503\times 10^{-6}}$

$R=3.97\times 10^{-3}\ \Omega$

So, the resistance in the flash tube is $3.97\times 10^{-3}\ \Omega$ . Hence, this is the required solution.

A lawnmower engine running for 20 minutes does 4560000 j of work. What is the power output of the engine

Alenkasestr [34]

<em>Answer: </em>

tim e (t) = 20 min.

= 20 × 60 = 1200 s ,

Work ( W) = 4560000 J

= 4560 KJ ,

Determine:

Power output (P) = Work ÷ time

= 4560 ÷ 1200

A car travels at an average speed of 60 km / h for 15 minutes. How far does the car travel in 15 minutes?

salantis [7]

Answer:

15km

Explanation:

Given parameters:

Average speed = 60km/hr

Time taken = 15min

Unknown:

Distance = ?

Solution:

The distance traveled can de derived using the expression below;

Distance = Average speed x time taken

Now let us convert the time to hr;

60min = 1hr

15min = $\frac{15}{60}$ = 0.25hr

Distance = 60km/hr x 0.25hr = 15km

A 0.171-kilogram hockey puck is struck by a hockey stick. If the force from the hockey stick is 30.2 Newtons, but the puck also

Komok [63]

Answer:

a = 156.14 m/s^2

Explanation:

Using the laws of newton:

∑F = ma

where ∑F is the sumatory of forces, m the mass and a the aceleration.

so:

F - $f_k$ = ma

where F is the force from the hockey stick and $f_k$ is the force of friction.

Replacing values, we get:

(30.2N) - (3.5N)= (0.171kg)a

Finally, solving for a:

a = 156.14 m/s^2

A car is traveling at 15m/s on a horizontal road. the brakes are applied and the car skids to a stop in 4.0s . the coefficient o

iren2701 [21]

Answer:

the coefficient of Kinetic friction between the tires and road is 0.38

Option A) .38 is the correct answer

Explanation:

Given that;

final velocity v = 0

initial velocity u = 15m/s

time taken t = 4 s

acceleration a = ?

from the equation of motion

v = u + at

we substitute

0 = 15 + a × 4

acceleration a = -15/4 = - 3.75 m/s²

the negative sign tells us that its a deacceleration so the sign can be ignored.

Deacceleration due to friction a = μ × g

we substitute

3.75 = μ × 9.8

μ = 3.75 / 9.8 = 0.3826 ≈ 0.38

Therefore the coefficient of Kinetic friction between the tires and road is 0.38

Option A) .38 is the correct answer
