Answer:

The shear deformation is \Delta x=3.34\times10^{-6}\ m.

Explanation:

Given that,

Shearing force F = 600 N

Shear modulus S = 1\times10^{9}\ N/m^2

length = 0.700 cm

diameter = 4.00 cm

We need to find the shear deformation

Using formula of shear modulus

S=\dfrac{Fl_{0}}{A\Delta x}

\Delta x=\dfrac{Fl_{0}}{(\dfrac{\pi d^2}{4})S}

\Delta x=\dfrac{4Fl_{0}}{\pi d^2 S}

Put the value into the formula

\Delta x=\dfrac{4\times600\times0.700\times10^{-2}}{3.14\times1\times10^{9}\times(4.00\times10^{-2})^2}

\Delta x=3.34\times10^{-6}\ m

Hence, The shear deformation is \Delta x=3.34\times10^{-6}\ m.

Joe and Max shake hands and say goodbye. Joe walks east 0.40 km to a coffee shop, and Max flags a cab and rides north 3.65 km to
katen-ka-za [31]

Answer:

3.67 km

Explanation:

Joe distance towards coffee shop is,

OB=0.40 km

And the Max distance towards bookstore is,

OA=3.65 km

Now the distance between the Joy and Max will be,

By applying pythagorus theorem,

AB=\sqrt{OB^{2}+OA^{2}}

Substitute 0.40 km for OB and 3.65 km for OA in the above equation.

AB=\sqrt{0.40^{2}+3.65^{2}}\\AB=\sqrt{13.4825} \\AB=3.67 km

Therefore the distance between there destination is 3.67 km.

A student who weighs 550 N is wearing a backpack that weighs 80 N. The student is standing still on level ground. Give your answ
siniylev [52]

Answer:

Explanation:

a) The magnitude of the net force on the student = 0 N since the student is standing still on level ground and upward reaction force = downward force.

b) the magnitude of the contact force on the student by the backpack = 80 N since the student was backing the backpack

c) the magnitude of the contact force o the student by the ground = 550 N + 80 N = 630 N reactional force on the student

The root-mean-square value of an alternating current of S0Hz frequency is 10 ampere. The time taken by the alternating current i
stealth61 [152]

Answer:

(D ) 5\times10^{-3} sec and 14.14 amp.

Explanation:

Given that, the rms value of current is 10 ampere and its frequency is 50 Hz.

Now maximum value of current can be calculated as,

I_{max}=\sqrt{2}I_{rms}\\I_{max}=10\times \sqrt{2}  \\I_{max}=14.14 amp.

The time period is defined as,

T=\frac{1}{f}\\ T=\frac{1}{50}\\ T=0.02 sec

Now the time taken by alternating current going from zero to maximum value is,

t=\frac{T}{4}\\ t=\frac{0.02}{4}\\ t=5\times 10^{-3}sec

Therefore, the time taken by alternating current to reach maximum value is t=5\times 10^{-3}sec and the peak value of current is 14.14 amp..
