Find the magnitude of the force needed to accelerate a 300 g mass with a⃗ = -0.205 m/s2 i^+0.700 m/s2 j
never [62]
F=ma
m=300g= 0.3kg
a= -0.205i +0.700j m/s2 = <-0205, 0.7>m/s2

Thus, F = 0.3<-0.205, 0.7> N
F = <-0.0615, 0.21> N
= -0.0615i N +0.2100j N

. Egbert is in a rowboat four miles from the nearest point on Egbert a straight shoreline. He wishes to reach a house 12 miles f
swat32

Answer:

t=\frac{13}{3} =4.33\ mi.hr^{-1}

Explanation:

Given:

  • Distance from the shore, s=4\ mi
  • distance of house from the shore, h=12\ mi
  • speed of rowing, v_r=3\ mi.hr^{-1}
  • speed of walking, v_w=4\ mi.hr^{-1}

<em>For the least amount of time to reach the house one must row at the nearest point on the shore and then walk from there.</em>

<u>Now the time taken to reach the shore:</u>

t_s=\frac{s}{v_s}

t_s=\frac{4}{3}\ mi.hr^{-1}

<u>Time taken in walking to house from the shore:</u>

t_h=\frac{h}{v_w}

t_h=\frac{12}{4}

t_h=\frac{12}{4}

t_h=3\ mi.hr^{-1}

<u>Therefore total time taken:</u>

t=t_h+t_s

t=\frac{13}{3} =4.33\ mi.hr^{-1}

Why are lights in house wired in house wired in a parallel or nothing series ​
navik [9.2K]
Parallel circuits are mostly used in houses because if you turn one light off the rest stay on. While with a series circuit, if you turn one light off, all the lights turn off as well because they are all connected to one circuit (series). Parallel is usually 2 or more circuits which is why it lets you turn one thing off and everything stays on.
