Answer:

Explanation:

One charge is situated at x = 1.95 m . Second charge is situated at y = 1.00 m

These two charges are situated outside sphere as it has radius of .365 m with center at origin. So charge inside sphere = zero.

Applying Gauss's theorem

Flux through spherical surface = charge inside sphere / ε₀

= 0 / ε₀

= 0 Ans .

A cylindrical bar of steel 10.1 mm (0.3976 in.) in diameter is to be deformed elastically by application of a force along the ba
amm1812

Answer:

14778.29 N

Explanation:

Diameter, d=10.1mm= 10.1*10^{-3}m

Since stress, \sigma= \frac {F}{A} where F is force, A is area and since specimen is cylindrical,  

A= \pi *(d/2)^{2}  Therefore, \sigma= \frac {F}{\pi*(0.5d)^{2}}

Also strain \epsilon= \frac { \triangle L}{L} where L is length

Poison’s ratio,v is the ratio of lateral strain to longitudinal strain hence

V= -\frac {\epsilon_{x}}{\epsilon_{z}}= \frac {\triangle dl_{o}}{d \triangle l}

From Hooke’s law, \sigma=E \epsilon_{z}

Conclusively, E* \epsilon_{z}=E* \frac {- \epsilon_{x}}{v}=\frac {F}{\pi*(0.5d)^{2}}

\frac {4F}{ \pi *d^{2}}=- \frac {E \triangle d}{vd}

F=- \frac {\pi *Ed \triangle d}{4v}

F= - \frac {\pi *207*10^{9} *10.1*10^{-3}* (-2.7*10^{-6})}{4*0.3}= 14778.29N

Therefore, required force F is 14778.29 N

Assume you are driving 20 mph on a straight road. Also, assume that at a speed of 20 miles per hour, it takes 100 feet to stop.
Viefleur [7K]

Answer:900  feet

Explanation:

Given

Velocity \left ( V_1\right )=20 mph\approx 29.334 ft/s

it take 100 feet to stop

Using Equation of motion

v^2-u^2=2as

where

v,u=Final and initial velocity

a=acceleration

s=distance moved

0-\left ( 29.334\right )^2=2\left (-a\right )\left ( 100\right )

a=\frac{29.334^2}{2\times 100}=4.302 ft/s^2

When velocity is 60 mph\approx 88.002 ft/s

v^2-u^2=2as

0-\left ( 88.002\right )^2=2\left ( -4.302\right )\left ( s\right )

s=900.08 feet

There is an electromagnetic wave traveling in the -z direction in a standard right-handed coordinate system. What is the directi
wlad13 [49]

Answer: The direction of the electric field, E→, is pointed in the +y direction.

Explanation:

One can use the right hand rule to illustrate the direction of travel of an electromagnetic and thereby get the directions of the electric field, magnetic field and direction of travel of the wave.

The right hand rule states that the direction of the thumb indicate the direction of travel of the electromagnetic wave (<em>in this case the -z direction</em>) and the curling of the fingers point in the direction of the magnetic field  B→ (<em>in this case the +x direction</em>), therefore, the electric field direction E→ is in the direction of the fingers which would be pointed towards the +y direction.

Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of wood is sitting on a frictionless sur
d1i1m1o1n [39]

Answer:

The speed of bullet and wooden bock coupled together, V = 22.22 m/s

Explanation:

Given that,

Mass of the bullet, m = 0.04 Kg

Mass of the wooden block, M = 0.5 Kg

The initial velocity of the bullet, u = 300 m/s

The initial velocity of the wooden block, U = 0 m/s

The final velocity of the bullet and wooden bock coupled together, V = 0 m/s

According to the conservation of linear momentum, the total momentum of the body after impact is equal to the total momentum before impact.

Therefore,

                              mV + MV = mu + MU

                               V(m+M) = mu

                                 V = mu/(m+M)

Substituting the values in the above equation,

                                V = 0.04 Kg x 300 m/s  / (0.04 Kg+ 0.5 Kg)

                                    = 22.22 m/s

Hence, the speed of bullet and wooden bock coupled together, V = 22.22 m/s

A runner generates 1260 W of thermal energy. If this heat has to be removed only by evaporation, how much water does this runner
sergey [27]

Answer:0.502kg

Explanation:

F4om the relation

Power x time = mass x latent heat of vapourization

P.t=ML

1260 * 15 *60 = M * 22.6 * 10^5

M= 1134000/(22.6 *10^5)

M=0.502kg=502g
