Answer:
Resistance in circuit = 0.53 ohm (Approx.)
Explanation:
Given:
Flow of current in circuit = 15 amp
Potential difference = 8 Volts
Find:
Resistance in circuit
Computation:
In an electrical system, resistance is a stopper of a material to electric current.
Resistance in circuit = Potential difference / Flow of current in circuit
Resistance in circuit = 8 / 15
Resistance in circuit = 0.53 ohm (Approx.)
well it depends on how much force was added but if they both have the same amount of force and they were rolled at the same time either they will bounce backwards or roll backwards not thats your question will they roll backwards are bounce backwards?
Answer:the force will remain same
Explanation:
because force is equal to the ratio of magnitude and distance
Answer:
t = 2.2 [days] and is there is a round trip, it will be double time t = 4.4 [days]
Explanation:
First, we need to arrange the problem to work in the same unit system (SI).
We need to convert the 1800 [miles] to meters, therefore:
![1800[miles] * \frac{1609.34[m]}{1[mile]} }=2896812[m] = 2896.8[km]](https://tex.z-dn.net/?f=1800%5Bmiles%5D%20%2A%20%5Cfrac%7B1609.34%5Bm%5D%7D%7B1%5Bmile%5D%7D%20%7D%3D2896812%5Bm%5D%20%3D%202896.8%5Bkm%5D)
Now using the following equation of kinematics, for the avarage velocity we have:
![v=\frac{x}{t} \\where \\v=velocity [m/s]\\t = time [s]\\x=distance traveled [m]\\](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bx%7D%7Bt%7D%20%5C%5Cwhere%20%5C%5Cv%3Dvelocity%20%5Bm%2Fs%5D%5C%5Ct%20%3D%20time%20%5Bs%5D%5C%5Cx%3Ddistance%20traveled%20%5Bm%5D%5C%5C)
therefore:
![t=\frac{x}{v} \\t=\frac{2896812}{15}\\ t=193120.8[s]](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bx%7D%7Bv%7D%20%5C%5Ct%3D%5Cfrac%7B2896812%7D%7B15%7D%5C%5C%20t%3D193120.8%5Bs%5D)
Now we can convert from seconds into days.
![193120.8[s]*\frac{1[hr]}{3600[s]}*\frac{1[day]}{24[hr]}\\ t = 2.2[days]](https://tex.z-dn.net/?f=193120.8%5Bs%5D%2A%5Cfrac%7B1%5Bhr%5D%7D%7B3600%5Bs%5D%7D%2A%5Cfrac%7B1%5Bday%5D%7D%7B24%5Bhr%5D%7D%5C%5C%20%20t%20%3D%202.2%5Bdays%5D)
Now if the truck has the need to come back, the team will spend double time.
t= 4.4 [days]
