The distance between two points needs to be measured, in meters. The true distance
between the points is 10 meters, but due to measurement error we can’t measure the
distance exactly. Instead, we will observe a value of 10+ϵ
ϵ, where the error ϵ
ϵ is distributed
(0,0.04)
N(0,0.04). Find the probability that the observed distance is within 0.4 meters of the
true distance (10 meters). Give both an exact answer in terms of Φ
Φ and an approximate
numerical answer.

An alternating source drives a series RLC circuit with an emf amplitude of 6.34 V, at a phase angle of +33.3°. When the potentia
Katena32 [7]

Answer:

V_{L}  =- 8.78v

Explanation:

E^{2} _{m}= V^{2} _{R} + (V_{L} -V _{C} )^{2}

OR  V_{L} = V_{c}  + \sqrt{E^{2}{m}  - V^{2} {R}  }

where VR = E{m}cosФ

V_{L} = V_{c}  + \sqrt{E^{2}_{m} - E^{2}_{m} cos^{2}   }Ф

V_{L} = V_{c} + {E_{m} \sqrt{1 - cos^{2} }  }Ф

V_{L} = V_{c} + E_{m}sinФ

substituting the given values

V_{L}  = 5.33 + 6.34 x sin33°

V_{L} = -8.78v

A light ray traveling through medium 1, index of refraction n1n1n_1 = 1.75, reaches the interface between medium 1 and medium 2,
horrorfan [7]

Answer:

θ₁ = 35.32°

Explanation:

given,

refractive index of medium 1 = n₁ = 1.75

refractive index of medium 2 = n₂ = 1.24

condition to describe the refracted angle

 \theta_{refracted} + \theta_{reflected}=90^0

 \theta_2 = 90^0-\theta_1...(1)

Using Snell's Law

   n₁ sin θ₁ = n₂ sin θ₂

θ₁ , θ₂ is the angle of incidence and refractive index

n₁. n₂ is the refractive index medium 1 and medium 2

   1.75 x  sin θ₁ = 1.24 x sin θ₂

From equation (1)

   1.75 x  sin θ₁ = 1.24 x sin (90-θ₁)

   1.75 sin θ₁ = 1.24 cos θ₁

      tan θ₁ = 0.708

         θ₁ = 35.32°

Hence, angle of incidence is equal to θ₁ = 35.32°

"A uniform cylinder of mass M and radius R is rolling without slipping. The velocity of its center of mass is v. What is the cyl
Goshia [24]

Answer:

Explanation:

Given

mass of cylinder is M

radius R

velocity of center of mass is v

As there is no slipping therefore cylinder will rotate as well as translate

Moment of inertia of cylinder I=\frac{MR^2}{2}

Kinetic Energy of cylinder K.E.=\frac{1}{2}Mv^2

Rotational energy R.E.=\frac{1}{2}I\omega ^2

for rolling

v=\omega \times r

where \omega =angular\ velocity\ of\ cylinder

R.E.=\frac{1}{2}\times \frac{MR^2}{2}\times (\frac{v}{R})^2=\frac{1}{4}Mv^2

Total kinetic Energy =\frac{1}{2}Mv^2+\frac{1}{4}Mv^2=\frac{3}{4}Mv^2

Give two example for push or pull to change the state of motion of time two examples​
dolphi86 [110]

Explanation:

An Example of push as a force would be to push on a swing. The force moves the swing in a particular direction and the harder that you push the further the swing will go.

An example of pull as a force would be opening a door. ...

An example of pressure as a force is when you push down on a pile of grapes. is this what you mean

Conversion fraction 1$=4q, how many are in 20$
Tom [10]

Answer:

\boxed{\sf 20 \$ = 80q}

Given:

1$ = 4q

To Find:

How many quarters are in 20$

Explanation:

To find out how many quarters are in 20$ we need to multiple 4 × 20.

\sf 1\$  = 4q

\sf  20\$  = 4 \times 20q

\sf = 80q
