Camera flashes charge a capacitor to high voltage by switching the current through an inductor on and off rapidly. In what time
Ber [7]

Answer:

The value is  \Delta  t = 4.0 *10^{-7} \  s

Explanation:

From the question we are told that

  The current is \Delta  I  = 0.100 \  A

  The  inductor  is L  =  2.0mH  =  2.0*10^{-3} \  H

  The voltage induced is  \epsilon   =  500 V

Generally the emf induced is mathematically represented as

      \epsilon =  L  *  \frac{\Delta I }{\Delta  t }

Here  \Delta  t is the time taken  

=>  \Delta  t =  \frac{L  * \Delta  I }{\epsilon }

=>  \Delta  t =  \frac{2*10^{-3}  * 0.100 }{500  }

=>  \Delta  t = 4.0 *10^{-7} \  s

A boy throws a stone straight upward with an initial speed of 15m/s. What maximum height will the stone reach before falling bac
Vitek1552 [10]
height=\frac{velocity^2}{2gravity}\\\\
velocity=15\frac{m}{s}\\\\
g=9,8\frac{m}{s^2}\\\\height=\frac{15^2}{2*9,8}=\frac{225}{19,6}\\\\
\boxed{height=11,48\ meters}

Blocks A and B of unknown masses m1 and m2, respectively, are set up on an inclined plane as shown. Block A is attached to block
Korvikt [17]

Newton's second law we can find that the correct answer is:  

 E)  It cannot be determiner whick block has more masses from the information provided

Newton's second law establishes the relationship between force, mass, and acceleration of a body. Since force and acceleration are vector quantities, their components must be added on each axis

For this problem we have two bodies, let's write Newton's second law for the body B, we assume that the body B descends

            W_b - T = m_b a

            W_b  = m_b g

            m_b - T = m_b a

Where W_b is the weight of block B, T the tension of the string, mb the mass of block b and the acceleration

Now let's find the relation for block A

let's set a datum with the x axis parallel to the ramp

           T - Wₓ = mₐ a

           sin θ = Wₓ / W

            Wₓ = Wₐ sin θ

             Wₐ = mₐ g

Where Wₓ is the component of the weight, Wₐ the weight of the body A and θ the angle of the plane

Let's write our system of equations

           m_b g - T = m_b a

           T - mₐ g sin θ = mₐ a

let's add the equations

            g (m_b - mₐ sin θ) = (m_b + mₐ) a

            a =   \frac{m_b - m_a \ sin  \ \theta}{m_b+m_a} \ g

Let's analyze this expression

  • The numerator is positive the body B descends, this occurs when

          m_b - mₐ sin θ > 0

           

  • The numerator is negative, body B rises

           m_b - mₐ  sin θ <0

We can observe that the acceleration is positive or negative depending on the relation of the masses and the angle of the plane.

In conclusion using Newton's second law we find that the correct answer is  

 E )   It cannot be determiner whick block has more masses from the information provided
