Answer:
Inclined planes are simple machines used to make work easier. Ramps, ladders, and staircases are all inclined planes.
Explanation:
<span>speed of slower=x; distance in 6 hours is 6x
speed of larger=2x; distance in 6 hours is 12x
12x-6x=204 miles
</span><span> 6x=204
x=34 mph slower, 204 miles in 6 hours.
2x=68 mph, faster, 408 miles in 6 hours, and difference is 204 miles</span>
Explanation:
Average power = change in energy / change in time
P = ΔE / Δt
P = (½ mv²) / t
P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)
P = 7.55 Watts
Answer:
I=1.48 A
Explanation:
Given that
B=3.1 x 10⁻5 T
b= 4.2 cm
l= 9.5 cm
The relationship for magnetic field and current given as
![B=\dfrac{2\mu _oI}{\pi}D](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B2%5Cmu%20_oI%7D%7B%5Cpi%7DD)
Where
![D=\dfrac{\sqrt{l^2+b^2}}{lb}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7B%5Csqrt%7Bl%5E2%2Bb%5E2%7D%7D%7Blb%7D)
By putting the values
![D=\dfrac{\sqrt{l^2+b^2}}{lb}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7B%5Csqrt%7Bl%5E2%2Bb%5E2%7D%7D%7Blb%7D)
![D=\dfrac{\sqrt{0.042^2+0.095^2}}{0.042\times 0.095}](https://tex.z-dn.net/?f=D%3D%5Cdfrac%7B%5Csqrt%7B0.042%5E2%2B0.095%5E2%7D%7D%7B0.042%5Ctimes%200.095%7D)
D=26.03 m⁻¹
![B=\dfrac{2\mu _oI}{\pi}D](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B2%5Cmu%20_oI%7D%7B%5Cpi%7DD)
![3.1\times 10^{-5}=\dfrac{2\times 4\times \pi \times 10^{-7} I}{\pi}\times 26.03](https://tex.z-dn.net/?f=3.1%5Ctimes%2010%5E%7B-5%7D%3D%5Cdfrac%7B2%5Ctimes%204%5Ctimes%20%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%20I%7D%7B%5Cpi%7D%5Ctimes%2026.03)
![I=\dfrac{3.1\times 10^{-5}}{{2\times 4\times 10^{-7} }\times 26.03}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B3.1%5Ctimes%2010%5E%7B-5%7D%7D%7B%7B2%5Ctimes%204%5Ctimes%2010%5E%7B-7%7D%20%7D%5Ctimes%2026.03%7D)
I=1.48 A
"F=Vector Sum Of The Two Forces" Is the answer.
