Answer:

1.62\times 10^{-8}\ \text{s}

Explanation:

\epsilon_0 = Vacuum permittivity = 8.854\times 10^{-12}\ \text{F/m}

A = Area = 10\times 2\times 10^{-4}\ \text{m}^2

d = Distance between plates = 1 mm

V_c = Changed voltage = 60 V

V = Initial voltage = 100 V

R = Resistance = 1000\ \Omega

Capacitance is given by

C=\dfrac{\epsilon_0A}{d}\\\Rightarrow C=\dfrac{8.854\times 10^{-12}\times 10\times 2\times 10^{-4}}{1\times 10^{-3}}\\\Rightarrow C=1.7708\times 10^{-11}\ \text{F}

We have the relation

V_c=V(1-e^{-\dfrac{t}{CR}})\\\Rightarrow e^{-\dfrac{t}{CR}}=1-\dfrac{V_c}{V}\\\Rightarrow -\dfrac{t}{CR}=\ln (1-\dfrac{V_c}{V})\\\Rightarrow t=-CR\ln (1-\dfrac{V_c}{V})\\\Rightarrow t=-1.7708\times 10^{-11}\times 1000\ln(1-\dfrac{60}{100})\\\Rightarrow t=1.62\times 10^{-8}\ \text{s}

The time taken for the potential difference to reach the required level is 1.62\times 10^{-8}\ \text{s}.

A mover applies a net force of 28 N to a sofa that has a mass of 70 kg.
Alinara [238K]

Answer: .4 m/s^2= acceleration

Explanation:

f = m*a

We can rearrange this equation to solve for acceleration. Therefore,

a=f/m

a= 28N/70kg

a= 0.4 m/s^2

A lever has an effort arm that is 8 meters long and the resistance arm that is 1.5 meters long, how much effort is needed to lif
ruslelena [56]
We are given with two measurements of the arm and an input weight. To answer this problem,we need to balance the forces and use the lengths of the arms. 
209 N * 8 m = x * 1.5 m
x = 1114.67 N

it takes 1114.67 N to lift the input weight

A white car is traveling at the legal speed limit v0 along an interstate highway. A blue car traveling in the same direction at
Allisa [31]

Answer:

the distance between two cars becomes d = \frac{v_o^2}{2a_b} when blue car travels at legal speed

Explanation:

Initially the relative speed of the two cars is given as

v_r = v_b - v_w

v_r = 2v_o - v_o = v_o

now the relative acceleration of blue car with respect to white car

a_r = -a_b

now the distance between two cars till the relative speed of two cars comes to zero

v_f^2 - v_i^2 = 2 a d

0 - v_o^2 = 2(-a_b)d

d = \frac{v_o^2}{2a_b}

so the distance between two cars becomes d = \frac{v_o^2}{2a_b} when blue car travels at legal speed
