How much energy does a 50-watt light bulb use compared to a 100-watt light bulb if both are shining for the same length of time?

The power required for an object to serve is function is equal to energy required per unit time. In this case, we have to bulbs: 50 watts and 100 watts. In the same length of time, it is expected that the 100 watt bulb has more energy than the 50 watt bulb, specifically two times the energy.

Does a ball rolling on an inclined plane have the same acceleration on the way up as it does on the way down?
larisa86 [58]

Answer:

No, it does not.

Explanation:

According to the Law of Gravitation, something going down has more kinetic energy than something going up because it attracts pressure from around it when going down. When it goes up, it has less gravitational force and inertia also stops the ball from rolling upward. Therefore, without the amount of kinetic energy, it will not have the same amount of acceleration.

enot [183]
According to the right hand grip rule; if you point your right thumb in the direction of the current flow and curl your fingers around the current carrying conductor, the fingers will point in the direction of the circular magnetic field around the conductor. Therefore,if the the current carrying carrying conductor is held with the current flowing towards you, using right hand grip rule the lines of magnetic field will act towards a counterclockwise direction or anticlockwise direction.

On Earth, the number flux of solar neutrinos from the p-p chain is:
Nataly [62]

Answer:

Explanation:

The volume of the tank = 50 kton

50 kton = 5 × 10⁷ kg

Since 18 grams of water will contain: 10 electrons × 6.023 × 10²³

Then;

5× 10⁷ kg will contain ( \dfrac{5 \times 10^7 \times 10^3}{18}) \times 10 \times 6.023 \times 10^{23}

= 1.67 × 10³⁴ electrons

(b)

Suppose:

f_{neutrino} = \dfrac{2f_o}{26.2 MeV} = 6.7\times 10^{10} \ s^{-1} cm^{-2}

Then;

10⁻⁶ of f_{neutrino} = 6.7 \times 10^{10} \times 10^{-6} \ s^{-1} cm^{-2}

=6.7 \times 10^{4}\ s^{-1} cm^{-2}

Thus, the number of high energy neutrinos which will interact with water is:

= 6.7 \times 10^4 \times \sigma

= 6.7 \times 10^4  \times 10^{-43}

= 6.7 \times 10^{-39} s^{-1}

For  1.67 × 10³⁴ electrons, the detection rate is:

6.7 \times 10^{-39}  \times 1.67 \times 10^{34}

= 11.19 \times 10^{-5} \ s^{-1}

= 9.668 per day
