<em><u>Option (D) is correct. The virtual image is always firmed in front of the lens or on the same side of the lens as of the object.</u></em>

Explanation:

The image formed by the lens are categorized in two broad categories.

  • Real Images
  • Virtual Images

The Real Image is a image that is formed by the actual meeting of the incoming rays from the object. The real image is an image that can be obtained on the screen.

The Virtual Image is an image that is formed by the the imaginary meeting of the incoming rays from the object. The virtual image cannot be obtained on the screen.

Since the real image is formed by the actual meeting of the rays, the rays would meet on the other side of the lens as that of the object. It means that a real image is formed behind the lens whereas for a virtual image, the diverging rays from object are extended in backward direction and made to meet on the same size as that of the object.

Thus, <em><u>Option (D) is correct. The virtual image is always firmed in front of the lens or on the same side of the lens as of the object.</u></em>

olga nikolaevna [1]

Answer:

B)

The magnitude of induced emf in the conducting loop is 0.99 mV.

Explanation:

Rate of increase in magnetic field per unit time = 0.090 T/s

Area of the conducting loop = 110 cm^2 = 0.0110 m^2

Electromagnetic induction is the production of an emf or voltage in a coil of wire due to a changing magnetic field through the coil.

Induced e.m.f is given as:

EMF = (-N*change in magnetic field/time)*Area

EMF = rate of change of magnetic field per unit time * Area

EMF = 0.090 * 0.0110

EMF = 0.00099 V

EMF = 0.99 mV

Two cars are raised to the same elevation on service- station lifts. If one car is twice as massive as the other, how do their p
Brums [2.3K]

Answer:

The potential energy of the more massive one is twice that of the other.

Explanation:

Potential energy is given by

<em>PE</em> = <em>mgh</em>

where <em>m</em> = mass of body, <em>g</em> = acceleration of gravity and <em>h</em> = height or elevation.

For the less massive car, let the mass be m_1. Then its <em>PE</em> is

PE_1 = m_1gh

For the massive car, let the mass be m_2.  Its <em>PE</em> is

PE_2 = m_2gh

But m_2 =2m_1

\therefore PE_2 = 2m_1gh = 2(m_1gh) = 2PE_1

Hence, the potential energy of the more massive one is twice that of the other.

A rubber-wheeled 50 kg cart rolls down a 35 degree concrete incline. Coefficient of rolling friction between rubber and concrete
lapo4ka [179]

Answer:

(a) 5.62 m/s²

(b) 5.46 m/s²

Explanation:

The given values are:

mass,

m = 50 kg

angle

= 35°

(a)

If friction neglected,

⇒ F_x=mgSin \theta=ma

⇒ a_x=gSin \theta

       =9.8 \ Sin35^{\circ}

       =5.62 \ m/s^2

(b)

If friction present,

⇒ F_x=mgCos \theta

⇒ F_x=mgSin \theta-\mu_r mgCos \theta

⇒ a=gSin \theta-\mu_rgCos \theta

      =9.8 \ Sin35^{\circ}-0.02\times 9.8 \ Cos30^{\circ}

      =5.46 \ m/s^2
