Answer:

because Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.

Answer:

υ = 5.62 x 10¹⁴ Hz

Explanation:

The process of of formation of photons takes place due to interaction of a particle with its anti-particle is called Annihilation of Matter. Here SPARTYON absorbs anti-SPARYTON to form 2 photons. Applying conservation of energy to the to this scenario, we get:

2(Energy of Each Photon) = Rest Mass Energy of SPARTYON + Rest Mass Energy of anti-SPARTYON

[tex]2hv = m_{0}c^2 + m_{0}c^2\\\\2hv = 2m_{0}c^2\\\\hv = m_{0}c^2\\\\v = \frac{m_{0}c^2}{h}[/tex]

where,

υ = frequency of each photon = ?

m₀ = rest mass of SPARTYON = mass of anti-SPARTYON = 455*Mass of electron

m₀ = 455(9.1 x 10⁻³¹ kg) = 4.14 x 10⁻²⁸ kg

c = speed of light = 3 x 10⁸ m/s

h = Plank's Constant = 6.625 x 10⁻³⁴ J.s

Therefore, using these values in the equation, we get:

[tex]v = \frac{(4.14 x 10^{-28} kg)(3 x 10^8 m/s)^2}{6.625 x 10^{-34}J.s}\\\\[/tex]

Answer:

[tex]R=519.61N[/tex]

Explanation:

From the question we are told that

Tension T on a cable are T=300N

Generally the tensions on a pulley is

       [tex]\sum f_x=T+T*cos(\theta)[/tex]

Therefore

      [tex]\sum f_x=300+300*cos(60)[/tex]

      [tex]\sum f_x=300 *1.5[/tex]

      [tex]\sum f_x=450N[/tex]

Hence

      [tex]T*sin(60) = 259.81N[/tex]

     [tex]R= 450\=i +259.81\=i[/tex]

Complete Question

A 8.0 A current is charging a 1.0 -cm-diameter parallel-plate capacitor. What is the magnetic field strength at a point 2.5 mm radially from the center of the wire leading to the capacitor?

Answer:

The magnetic field is  [tex]B = 6.4*10^{-4} \ T[/tex]

Explanation:

From the question we are told that

    The current is  [tex]I = 8.0 \ A[/tex]

    The diameter is  [tex]d = \ cm = \frac{1}{100} = 0.01 m[/tex]

      The position considered is  [tex]d = 2.5 \ mm = 0.0025 \ m[/tex]

 Generally the magnetic field is mathematically represented as

           [tex]B = \frac{\mu_o * I }{ 2 \pi d}[/tex]

Here [tex]\mu_o[/tex] is permeability of free space with value  

[tex]\mu_o = 4\pi * 10^{-7} \ N/A^2[/tex]

      So

                 [tex]B = \frac{ 4\pi * 10^{-7} * 8 }{ 2 \pi * 0.0025 }[/tex]

=>               [tex]B = \frac{ 2 * 10^{-7} * 8 }{ * 0.0025 }[/tex]

=>               [tex]B = 6.4*10^{-4} \ T[/tex]

The box is accelerated from rest to 4 m/s in a matter of 2.5 s, so its acceleration a is such that

4 m/s = a (2.5 s)   →   a = (4 m/s) / (2.5 s) = 1.6 m/s²

Then the force applied to the box has a magnitude F such that

F = (10 kg) (1.6 m/s²) = 16 N

Answer:

The correct option is (a).

Explanation:

Given that,

Radius of a horizontal circle, r = 80 cm = 0.8 m

Angular velocity, ω = 5 rev/minute = 0.523 rad/s

We need to find the magnitude of its centripetal acceleration. The formula that is used to find the centripetal acceleration is given by :

[tex]a=\omega^2 r\\\\a=(0.523)^2\times 0.8\\\\a=0.218\ m/s^2[/tex]

or

[tex]a=0.22\ m/s^2[/tex]

So, the magnitude of its acceleration is [tex]0.22\ m/s^2[/tex].

Answer:

Explanation:

Force of friction acting on the body = μ mg cosθ

= .4  x 70 x 9.8 x cos30

= 237.63 N

component of weight = mgsinθ

= 70 x 9.8 x sin30

= 343 N  

Net upward force = 600 - mgsinθ - μ mg cosθ

= 600 - 343 - 237.63

= 105.37 N

acceleration in upward direction = 105.37 / 70

= 1.5 m /s²

s = ut + 1/2 a t²

= 0 + .5 x 1.5 x 3²

= 6.75 m .

The crate will move at a distance of 1.215 m in 3 seconds.

Given that the mass m of the crate is 70 kg and the angle above the horizontal is 30°. External force F on the crate is 600 N and the coefficient of friction is 0.4.

The friction force applied to the crate is calculated as given below.

Friction force = [tex]\mu mgcos \theta[/tex]

Where [tex]\mu[/tex] is the friction constant, g is the gravitational acceleration and [tex]\theta[/tex] is the angle above the horizontal.

Friction Force = [tex]0.4\times 70\times 9.8\times cos30^\circ[/tex]

Friction force = 237.63 N.

There is a force applied on the crate due to its weight is calculated as given below.

Force (weight component) = [tex]mgsin\theta[/tex]

Force (weight component) = [tex]70\times 9.8\times sin 30^\circ[/tex]

Force (weight component) = 343 N.

The net force applied to the crate is given below.

Net force = External force - friction force - force (weight component)

Net force F' = [tex]600 - 237.63 - 343[/tex]

Net force F' = 19.37 N.

The acceleration of the crate can be calculated as given below.

[tex]a = \dfrac {F'}{m}[/tex]

[tex]a =\dfrac {19.37}{70}[/tex]

[tex]a = 0.27 \;\rm m/s^2[/tex]

Hence the distance traveled by the crate in 3 seconds is calculated by the formula given below.

[tex]s = ut + \dfrac {1}{2} at^2[/tex]

Where, s is the distance, u is the initial velocity, a is the acceleration and t is the time of motion of the crate.

[tex]s = 0\times 3 + \dfrac {1}{2} \times 0.27 \times 3^2[/tex]

[tex]s = 1.215[/tex]

Hence we can conclude that the crate will move a distance of 1.215 m in 3 seconds.

Answer:

875.59 N/m

Explanation:

From the question given above, the following data were obtained:

Force (F) = 10 lb

Extention (e) = 2 in

Spring constant (K) =?

Next, we shall convert 10 lb to Newton (N). This can be obtained as follow:

1 lb = 4.448 N

Therefore,

10 lb = 10 lb × 4.448 N / 1 lb

10 lb = 44.48 N

Thus, 10 lb is equivalent to 44.48 N

Next, we shall convert 2 in to metre (m). This can be obtained as follow:

1 in = 0.0254 m

Therefore,

2 in = 2 in × 0.0254 m / 1 in

2 in = 0.0508 m

Thus, 2 in is equivalent to 0.0508 m.

Finally, we shall determine the spring constant i.e the stiffness of the spring as follow:

Force (F) = 44.48 N

Extention (e) = 0.0508 m.

Spring constant (K) =?

F = Ke

44.48 = K × 0.0508

Divide both side by 0.0508

K = 44.48 / 0.0508

K = 875.59 N/m

Therefore the spring constant i.e the stiffness of the spring is 875.59 N/m

Answer:

[tex]y = 4.36[/tex]

Explanation:

Let the height of the ladder be L

[tex]L = 10[/tex]

Also:

When the ladder leans against the wall, it forms a triangle and the length of the ladder forms the hypotenuse.

So, we have:

[tex]L^2 = x^2 + y^2[/tex] --- Pythagoras Theorem

When the base is 9ft from the wall, this means that:

[tex]x = 9[/tex]

Substitute 9 for x and 10 for L in [tex]L^2 = x^2 + y^2[/tex]

[tex]10^2 = 9^2 + y^2[/tex]

[tex]100 = 81 + y^2[/tex]

Make [tex]y^2[/tex] the subject

[tex]y^2 = 100 - 81[/tex]

[tex]y^2 = 19[/tex]

Make y the subject

[tex]y = \sqrt{19[/tex]

[tex]y = 4.36[/tex]

Hence, the true distance at that point is approximately 4.36ft

The true statement about the true distance between the top of the ladder and the ground when the base is 9 feets from the wall is - 9/√19

Let :

Ladder forms a right angle triangle as it leans against the wall :

Hence, we have :

Taking the implicit derivative of both sides:

2xdx/dt + 2ydy/dt = 0

xdx/dt + ydy/dt = 0

ydy/dt = - xdx/dt

dy/dt = (-xdx/dt) / y

When the ladder is 9 ft from the wall;

81 + y² = 100

y² = 100 - 81 = 19

y = √19

Substituting into the equation :

dy/dt = -9(1)/√19

Hence, dy/dt = - 9/√19

Conservation of momentum

Explanation:

Out of the two options given, the more appropriate one is the law of conservation of momentum. This is particularly so because momentum deals with the velocity or speed of the car while considering its mass. So, if a large car is to collide with another car, small one, then the momentum is what is considered. Energy on the other hand is talking about the work that is done, while the momentum considers the mass of the car while it is moving and considering its speed also

Explanation:

To solve this exercise we can use conservation of mechanical energy

Starting point. Just clearing

          Em₀ = K + U = ½ m v² - G m M / [tex]R_{e}[/tex]

Final point. At r = 14R_{e}

        Em_{f} = U = -G m M / 14R_{e}

how energy is conserved

         Em₀ = [tex]Em_{f}[/tex]

         ½ m v² - G m M /R_{e} = -G m M / 14R_{e}

        ½ v² = G M / R_{e} (-1/14 + 1)

        v² = 2 G M / R_{e} 13/14

we calculate

       v² = 2 6.67 10⁻¹¹ 5.98 10²⁴ / 6.37 10⁶ 13/14

       v = √ (1,16 10⁸)

       v = 1.078 10⁴ m / s
