Complete Question

The diagram for this question is shown on the first uploaded image

Answer:

x  =  4.70  \  m     ,   y =  0.2803 \  m

Explanation:

From the question we are told that

     The initial velocity of the arcade ball is  u  =  7.0 \  m/s

     The time taken by the ball to enter the basket is  t =  0.95 \ s

Generally the x -component of the initial  velocity is  

            u_x  =  7 *  cos (45)    

=>         u_x  =  4.95 \  m/s

Generally the y -component of the initial  velocity is  

            u_x  =  7 *  sin(45)    

=>         u_y  =  4.95 \  m/s

  Generally the distance x is mathematically represented as

                 x  =  u_x  *  t

=>              x  =  4.95 *  0.95      

=>              x  =  4.70  \  m    

Generally from kinematic equation the distance y is mathematically represented as

               y =  u_y * t  - \frac{1}{2} *  g * t^2

=>            y = 4.95 * 0.95  - \frac{1}{2} *  9.8 * 0.95^2

=>            y =  0.2803 \  m

A molecule of roughly spherical shape has a mass of 6.10 × 10-25 kg and a diameter of 0.70 nm. The uncertainty in the measured p
Ilia_Sergeevich [38]

Answer:

\Delta v = 0.123 m/s

Explanation:

As per the law of uncertainty we know that

\Delta p \times \Delta x = \frac{h}{4\pi}

now we know that

\Delta x = 0.70 nm

m = 6.10 \times 10^{-25}

also we have

h = 6.626 \times 10^{-34} J.s

now we will have

m\Delta v \times \Delta x = \frac{h}{4\pi}

(6.10 \times 10^{-25})\Delta v \times (0.70 \times 10^{-9}) = \frac{6.626 \times 10^{-34}}{4\pi}

\Delta v= 0.123 m/s

A fence 8 ft high​ (w) runs parallel to a tall building and is 24 ft​ (d) from it. Find the length​ (L) of the shortest ladder t
AveGali [126]

Answer:

25.3 ft

Explanation:

The illustration of the problem is shown the attached image.

The length of the ladder can be calculated using the Pythagoras theorem:

Hypotenuse^2 = opposite^2 + adjacent^2

The hypotenuse is the length of the ladder.

Hypotenuse = \sqrt{opposite^2 + adjacent^2}

L^2 = BC^2 + (24 + AE)^2........1

Triangle ABC is similar to triangle AEF, hence:

\frac{BC}{8} = \frac{AE + 24}{AE}

BC = \frac{8(AE + 24)}{AE}.................2

Substitute 2 into 1

L^2 = (\frac{8(AE + 24)}{AE})^2 + (24 + AE)^2

Let AE = x

L^2 = (\frac{8x + 192}{x})^2 + (24 + x)^2

    = (8 + \frac{192}{x})^2 + (24 + x)^2

Minimize L with respect to x.

2\frac{dL}{dx} = 2(8 + \frac{192}{x})(-\frac{192}{x^2}) + 2(24 + x)

       =

What are some ways that electric fields are similar to magnetic fields?
sattari [20]

Answer:

The correct answers are the proportionality of the fields concerning distance, vector fields, and forces at a distance.

Explanation:

The similarities between magnetic fields and electric fields are that electric fields are produced by two charges that can be positive and negative. Magnetic fields are associated with two magnetic poles, although they are also produced by moving charges. Both fields are inversely proportional to the square of the distance between the sources, both fields are vectorial and both act by distant forces.

( 8c5p79) A certain force gives mass m1 an acceleration of 13.5 m/s2 and mass m2 an acceleration of 3.5 m/s2. What acceleration
Talja [164]

Answer:

4.725 m/s^{2}

Explanation:

We know that from Newton's second law of motion, F=ma hence making acceleration the subject then a=\frac {F}{m}  where a is acceleration, F is force and m is mass

Also making mass the subject of the formula m=\frac {F}{a}

For m1= \frac {F}{13.5} and m2=\frac {F}{3.5} hence F=(m2-m1)a= (\frac {F}{3.5}-\frac {F}{13.5})a=0.2116402116\\\frac {1}{a}=0.2116402116\\a=4.725 m/s^{2}
