Find the equivalent resistance of this parallel circuit with two strands.

1 answer:

6 0

In a parallel circuit, the total resistance calculated from the individual resistances is computed from the formula: 1/Rt = 1/R1 + 1/R2. substituting R1 and R2, then
1/Rt = 1/7 + 1/49
1/Rt = 1/6.125 = 1/ 49/8
Rt = 49/8 <span>Ω

The total resistance hence is </span>49/8 Ω

It takes four hydrogen nuclei to create one helium nucleus in the proton–proton chain, which is the main energy source of the Su

Artyom0805 [142]

Answer:

0.1371 * 10 ^ -27 kg

Explanation:

From the question number of hydrogen nuclei used to form 3 Helium nuclei = 12 ( 4 * 3 )

mass of the 12 hydrogen nuclei = 12 *( 1.6726 *10^-27) = 20.0712 * 10 ^-27

mass of single helium = 6.6447 * 10 ^-27 kg

therefore the mass of the 3 helium = 3 *( 6.6447 *10 ^-27) = 19.9341 * 10 ^-27 kg

The mass difference between the hydrogen and the helium used

= (20.0712 * 10^ -27) - (19.9341 * 10 ^-27) = 0.1371 * 10 ^ -27 kg

therefore 0.1371 * 10^-27 kg is converted into energy to create the three helium nuclei

How does Newton's 2nd law relate to Moment of Inertia?

ki77a [65]

When a torque is applied to an object it rotates with acceleration which is inversely proportional to its moment of inertia. The moment of inertia is a rotational mass and the torque is a rotational force

A geologist finds that a Moon rock whose mass is 8.94 kg has an apparent mass of 6.18 kg when submerged in water. What is the de

Grace [21]

Density of rock = 3.23 Kg/m^3

Given:

mass of Moon rock = 8.94 kg

apparent mass of Moon rock = 6.18 kg

To Find:

density of the rock

Solution: It is a universal fact that mass of an object remains constant whether measured on earth or on moon.

Mass of rock on moon/earth = 8.94 kg

When the block is immersed in water then;

Loss in weight = weight of water displaced

Loss in weight = 8.94 - 6.18 = 2.76 kg

As we know that water has a density of 1g/cm^3 (1000kg/m^3)

Volume of water = volume of the rock = Mass/density = 2.76 kg

density of rock mass/volume = 8.94/2.76 = 3.23 Kg/m^3

Density of rock = 3.23 Kg/m^3
