Answer:

Δt = 2.47 s

Explanation:

The problem involves just the formula of the acceleration:

a =  \frac{Δv}{Δt}

Δv = (27.7 - 0) \: m/s

You want to know Δt, knowing the time and the speed. So:

Δt = Δv/a

Δt = 2.47 s

8_murik_8 [283]

Answer:

The gplanet is 0.193 m/s^2

Explanation:

The speed of the pulse is:

v=\frac{lengthofthewipe}{traveltime} =\frac{1.6}{0.0656} =15.24m/s

v=\sqrt{\frac{MgL}{m} } \\v^{2} =\frac{MgL}{m} \\g=\frac{mv^{2} }{ML}

where

m=mass of the wire=4 g= 4x10^-3 kg

M=mass of the object= 3 kg

Replacing values:

g=\frac{4x10^{-3}*15.24^{2}  }{3*1.6} =0.193 m/s^{2}

Why are insulators important?
GenaCL600 [577]

Answer:

An insulator opposes the flow of electricity. Insulators are important to keep us safe from electricity. The wire that carries electricity to your computer or television is covered with a rubber-like insulator that protects you from getting electrocuted. Good insulators include glass, the air, and paper.

A tank holds a 1.44-m thick layer of oil that floats on a 0.98-m thick layer of brine. Both liquids are clear and do not intermi
denpristay [2]

Answer:

Angle of ray makes with the vertical is 62.1 degree

Explanation:

As per the ray diagram we know that the angle of incidence on oil brine interface will be given as

tan\theta_i = \frac{0.7}{0.98}

\theta_i = 35.5^0

now by Snell'a law at that interface we have

\mu_1 sin\theta_i = \mu_2 sin \theta_r

now we will have

1.52  sin35.5 = 1.40 sin\theta_r

\theta_r = 39.12^0

now this is the angle of incidence for oil air interface

so now again by Snell's law we will have

\mu_2 sin\theta_i' = \mu_{air} sin\theta

1.40 sin39.12 = 1 sin\theta

\theta = 62.1^0
