how much current would be measured in a circuit if the light bulb has a resistance of 6 ohms and a voltage of 36 volts
Stels [109]

Answer:

The right response is "6 A". A further explanation is given below.

Explanation:

The given values are:

Resistance,

R = 6 ohms

Voltage,

V = 36 volts

As we know,

⇒  V=IR

then,

⇒  I=\frac{V}{R}

On substituting the values, we get

⇒     =\frac{36}{6}

⇒     =6 \ A

An atom of 70kr has a mass of 69. 955264 amu. mass of1h atom = 1. 007825 amu mass of a neutron = 1. 008665 amu. calculate the bi

The binding energy in MeV per atom is - 63284.56 Mev.

The amount of energy needed to detach a particle from a system of particles or to disperse every particle in the system is known as the binding energy. Subatomic particles in atomic nuclei, electrons attached to atom's nuclei, and atoms and ions bonded together in crystals are three examples of where binding energy is very relevant.

If we have a nucleus with Z protons and N neutrons and mass MA, where A = Z + N then its binding energy in MeV is given by: Eb(MeV) = (Zmp + Nmn - MA) x 931.494 MeV/u

Mass of atom = 69.955264 amu

Mass of proton = 1.007825 amu

Mass of neutron = 1.008665 amu

Binding energy, Mev = (Zmp + Nmn - M) × 931.494MeV/u

                                    = ( 1.007825 + 1.008665 -  69.955264) × 931.494

                                    = - 67.938774 × 931.494

                                    = - 63284.56 Mev

Therefore, the binding energy in MeV per atom is - 63284.56 Mev.

How many grams of water are produced when oxygen reacts with an excessive amount of propane (C3H8)?
lora16 [44]

Answer:

From the equation you will see that 1 mol of propane generates 4 mols of water.

Since the molar mass of water  

M ( H2O)=2×1+16=18g/mol

2 mol propane will generate  

2 ×4×18=144g   of water

Explanation:

Since the molar mass of water  

M ( H2O)=2×1+16=18g/mol

2 mol propane will generate  

2 ×4×18=144g   of water
