6.A truck is carrying a steel beam of length 13.0 m on a freeway. An accident causes the beam to be dumped off the truck and sli

de horizontally along the ground at a speed of 30.0 m/s. The velocity of the center of mass of the beam is northward while the length of the beam maintains an east–west orientation. The vertical component of the Earth's magnetic field at this location has a magnitude of 30.0 T. What is the magnitude of the induced emf between the ends of the beam?

The magnitude is 13.12 mV.

The steps are attached below.

<h3>How do you find the magnitude of an induced emf?</h3>

The standard SI unit of the magnetic field is the tesla (T). As an end result, we can use these equations and the equation for an induced emf due to changes in magnetic flux, ϵ=−NΔϕΔt ϵ = − N Δ ϕ Δ t, to calculate the importance of a precipitated emf in a solenoid.

The magnitude of the precipitated contemporary depends on the rate of trade of magnetic flux or the fee of reducing the magnetic area strains.

i believe it would be the same because time doesn't matter when calculating total work done.

Work=FxD

F=force

A car driving on a straight track accelerates at a rate of 3.2 m/s^2 for 14 sec. If the initial velocity of the car was 5.1 m/s,
Andreyy89

The final position of the car is 385 m.

Explanation:

We know the formula :

                                   s = ut +  \frac{1}{2} at^{2}

where,

                                     s = distance

                                     u = initial velocity = 5.1 m/s

                                      t = time taken = 14 sec

                                     a = acceleration = 3.2 m/s^{2}

Solving:

                         s = 5.1* 14 + \frac{1}{2} * 3.2 * 14^{2}

                      ∴ s = 385 m

Hence the final position of the car is 385 m.

A stuntman of mass 48 kg is to be launched horizontally out of a spring-
Damm [24]

The velocity of the stuntman, once he has left the cannon is 5 m/s.

The right option is O A. 5 m/s

The Kinetic energy of the stuntman is equal to the elastic potential energy of the spring.

<h3 /><h3>Velocity: </h3>

This is the ratio of displacement to time. The S.I unit of Velocity is m/s.  The velocity of the stuntman can be calculated using the formula below.

⇒ Formula:

  • mv²/2 = ke²/2
  • mv² = ke².................. Equation 1

⇒ Where:

  • m = mass of the stuntman
  • v = velocity of the stuntman
  • k = force constant of the spring
  • e = compression of the spring

⇒ Make v the subject of the equation

  • v = √(ke²/m)................. Equation 2

From the question,

⇒ Given:

  • m = 48 kg
  • k = 75 N/m
  • e = 4 m

⇒ Substitute these values into equation 2

  • v = √[(75×4²)/48]
  • v = √25
  • v = 5 m/s.

Hence, The velocity of the stuntman, once he has left the cannon is 5 m/s.

The right option is O A. 5 m/s

Match the element with its description.
zubka84 [21]

Answer:

Sodium -  D) Malleable, soft, and shiny

 Sodium is an alkalyne metals that is why they are soft and sodium can cut by knife.

Silicon  -  C) Has properties of both metals and nonmetals

 As we know that those materials have both nonmetals and  metals  properties are known as metaloid.

Bromine  -  A) Highly reactive gas

 All halogens are so reactive .Because they are high electro negative element.Bromine(Br) is a halogen element.

Argon - B) Nonreactive gas

  All noble gases are stable that is why they are not reactive with ant other element.So we can say that noble gas are  Nonreactive gas.Argon(Ar) is noble gas.
