You leave your home at 1pm. At 3pm, you are 100 km east of your house. What was your average velocity in km/hr
Rasek [7]

Answer:

50km/h

Explanation:

Average velocity = change in distance (or distance travelled) divided by/ the change in time (or time taken.)

The change in distance has been given as 100km.

The change in time is 3pm-1pm = 2 hours.

Therefore the average velocity was 100/2 = 50km/h (to the east).

Hope this helped!

7. A spring balance reads force in Newton. The scale is 20 cm long and reads from 0 to
GarryVolchara [31]

Answer:

The potential  energy when it reads 40 N is PE  = 5.33 \ J

Explanation:

From the question we are told that

   The lowest reading of the spring balance is  0 N and this is at  0 cm = 0 m

   The height reading of the spring balance is 60 N  and this is at 20 cm =  0.20 m

   Generally the length corresponding to the reading of 40 N is mathematically represented as

       d = \frac{40 * 0.20 }{60 }

=>    d = 0.133 \  m

Generally the potential  energy is mathematically represented as

      PE = m * g * d

Here

     F = mg  =  40 N

So  

     PE = 40 * 0.133

=>  PE  = 5.33 \ J

A capacitor consists of two closely spaced metal conductors of large area, separated by a thin insulating foil. It has an electr
Oksi-84 [34.3K]

Answer:

1 = 5.4 J

2 = 0.1979 C

3 = 5

Explanation:

Energy in a capacitor, E is

E = 1/2 * C * V²

E = 1/2 * 3000*10^-6 * 60²

E = 1/2 * 3000*10^-6 * 3600

E = 1/2 * 10.8

E = 5.4 J

E = Q²/2C = 6.53 J

E * 2C = Q²

Q² = 6.53 * 2 * 3000*10^-6

Q² = 13.06 * 3000*10^-6

Q² = 0.03918

Q = √0.03918

Q = 0.1979 C

The Capacitor, C is inversely proportional to the distance of separation, D. Thus, if D is increased by 5 to be 5D, then C would be C/5. And therefore, our energy stored in the capacitor is increased by a factor of 5.

If the current direction is reversed in one of the strips, the magnetic field in a point A located outside the space between the
serious [3.7K]

Answer:

Twice the initial value

Explanation:

Let the current be  = I

      the width of the conducting strips be = a

We know that magnetic field between two plates is given by

$B=\frac{\mu_0 I}{2\pi r}$

If the direction of this magnetic field is same between the two plates, then

$B=\frac{\mu_0 I}{2\pi r} - \frac{\mu_0 I}{2\pi r}$

  = 0

And when the currents runs opposite at each plate, then

$B=\frac{\mu_0 I}{2\pi r} + \frac{\mu_0 I}{2\pi r}$

    $2 \times B_{initial}$

Hence the magnetic field will be twice the initial value of the magnetic field that runs between the plates.
