What material is most commonly used to make a photovoltaic solar cell?
zaharov [31]

Solar cells can be classified into first, second and third generation cells. The first generation cells—also called conventional, traditional or wafer-based cells—are made of crystalline silicon, the commercially predominant PV technology, that includes materials such as polysilicon and monocrystalline silicon.

A particular galaxy is observed to have a recessional velocity (away from Earth) of 30,000 km/s. Assuming the Hubble constant to
Yakvenalex [24]

Answer: 428.57 Mpc

Explanation:

Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum, and noted that all galaxies are "moving away from each other with a speed that increases with distance", and enunciated the now called Hubble–Lemaître Law.  

This is mathematically expressed as:

V=H_{o}D (1)

Where:

V=30,000 km/s is the recession velocity of the galaxy

H_{o}=70 km/s/Mpc is the Hubble constant  

D is the distance

Isolating D from (1):

D=\frac{V}{H_{o}} (2)

D=\frac{30,000 km/s}{70 km/s/Mpc} (3)

Finally:

D=428.57 Mpc

Emily holds a banana of mass m over the edge of a bridge of height h. She drops the banana and it falls to the river below. Use
Mariana [72]

Answer:

The mass of the banana is m and it is at height h.

Applying the Law of Conservation of Energy

              Total Energy before fall = Total Energy after fall

                                E_{i}  = E_{f}

Here, total energy is the sum of kinetic energy and potential energy

K.E_{i} + P.E_{i} = K.E_{f} + P.E_{f}       (a)

When banana is at height h, it has

                 K.E_{i} = 0    and    P.E_{i} = mgh          

and when it reaches the river, it has

       K.E_{f}  = 1/2mv^{2}    and   P.E_{f}  = 0

Putting the values in equation (a)

                              0 + mgh = 1/2mv^{2} + 0

                                      mgh = 1/2mv^{2}

<em>cutting 'm' from both sides</em>

<em>                                           </em>gh = 1/2v^{2}

                                          v = \sqrt{2gh}

Hence, the velocity of banana before hitting the water is

                                          v = \sqrt{2gh}
