Average speed  =  (total distance)  /  (total time to cover the distance)

                             =  (15 km + 33 km)  /  (1 hr + 2 hrs)

                             =      (48 km)          /    (3 hrs)

                             =                    (48/3)    km/hr

                             =                       16      km/hr .

The force exerted on the tires of a car that directly accelerate it along a road is exerted by the
azamat

The force exerted on the tires of a car that directly accelerate it along a road is exerted by the road friction.

<h3>What is force?</h3>

Force is defined as the product of mass and acceleration of an object.

Friction is defined as the force that resists the movement of an object over another.

Therefore, the force exerted on the tires of a car that directly accelerate it along a road is exerted by the road friction.

An 18.5-cm-diameter loop of wire is initially oriented perpendicular to a 1.5-T magnetic field. The loop is rotated so that its
nikdorinn [45]

Answer:

The average induced emf in the loop is 0.20 V

Explanation:

Given:

Radius of loop r = \frac{d}{2} = 9.25 \times 10^{-2} m

Magnetic field B = 1.5 T

Change in time \Delta t = 0.20 sec

According to the faraday's law,

Induced emf is given by

    \epsilon = -\frac{\Delta \phi}{\Delta t}

Where \phi = magnetic flux

  \phi = BA\cos0                                ( here \theta = 0 )      

Where A = \pi r^{2}

We neglect minus sign because it's shows lenz law

   \epsilon  = \frac{B \pi r^{2}  }{\Delta t}

   \epsilon = \frac{1.5 \times 3.14 \times (9.25 \times 10^{-2} )^{2} }{0.20}

   \epsilon = 0.20 V

Therefore, the average induced emf in the loop is 0.20 V
