Displacement=1200m
Time=4min=4(60)=240s

$\boxed{\sf Velocity=\dfrac{Displacement}{Time}}$

$\\ \sf\longmapsto Velocity=\dfrac{1200}{240}$

$\\ \sf\longmapsto Velocity=5m/s$

One boat tows another boat by means of a tow line, which is under a constant tension of 465 N. The boats move at a constant spee

Ludmilka [50]

Answer:

Work done, W = 141174 Joules

Explanation:

It is given that,

Constant tension acting on the boat, T = F = 465 N

Speed of the boat, v = 4.6 m/s

Time, t = 1.1 min = 66 seconds

Let W is the work done by the tension. It is equal to the product of force and displacement. It is given by :

$W=F\times d$

Since, $d=vt$

$W=F\times v\times t$

$W=465\ N\times 4.6\ m/s\times 66\ s$

W = 141174 Joules

So, the work is done by the tension is 141174 Joules. Hence, this is the required solution.

how will you connect three resistors of 2 ohm centrioles and 5 ohms respectively so as obtain of the result and the resistance o

victus00 [196]

Two resistor of 2Ω in series parallel to resistor 5Ω in series to a 2Ω resistor. This configuration gives to us an equivalent resistor of 2.55Ω.

To solve this problem we have to use the rules of conection of resistor in series and parallel.

A resistor R1 in serie with other resistor R2 gives us an equivalent resistor Req= R1 + R2.

A resistor R1 in parallel with other resistor R2 gives us an equivalent resistor Req = R1.R2/R1+R2.

The circuit that show an arregement of resistor which we obtain a equivalent resistor of 2.5Ω from three resistor of 2Ω and 5Ω respectively is attached in the image:

What is the average flow rate in cm3/s of gasoline to the engine of a car traveling at 100 km/h if it averages 10. 0 km/l?

DiKsa [7]

The answer is $2.78 \mathrm{~cm}^{3} / \mathrm{s}$

$Q=\frac{1 \mathrm{~L}}{10.0 \mathrm{~km}} \times \frac{100 \mathrm{~km}}{\mathrm{~h}} \times \frac{1 \mathrm{~h}}{36005} \times \frac{1000 \mathrm{~cm}^{3}}{\mathrm{~L}}$ = $2.78 \mathrm{~cm}^{3} / \mathrm{s}$

Thus, the average flow rate is $2.78 \mathrm{~cm}^{3} / \mathrm{s}$ .

What is average flow rate?

Average flow, which is often represented in cubic feet per second, refers to the stream's average discharge at a certain location.
The flowrate is the rate at which liquid travels through a pipe or into a wellbore from a reservoir.
The volume of fluid that moves across a specific cross-sectional area per unit of time is known as the flow rate.
It is essential to measure flow rates accurately using the right flowmeters to guarantee that fluid management procedures are efficient, safe, and cost-effective.
