Answer:

Vₑ = 9.314569 × 10^8 eV

Vₑ = 931.5 ×10^6 eV

Vₑ = 931.5 MeV

Verified

Explanation:

Applying the Einstein equation which shows that energy and mass are interchangeable (related). Which can be written mathematically as;

E = mc^2 ......1

Where E = energy

m = mass

c = speed of light

Energy can also be related to potential difference and charge as;

E = qv ........2

Where;

E = energy

q = charge

v = potential difference

Substituting equation 2 into 1

qv = mc^2

Making v the subject of formula

v = (mc^2)/q .........3

For a unified atomic mass unit is defined to be 1 u = 1.6605 ✕ 10−27 kg

m = 1.6605 × 10^−27 kg

c = 2.9979 × 10^8 m/s

Charge on electron qₑ = 1.6021766 × 10^-19 Coulomb

So, equation 3 becomes;

Vₑ = (mc^2)/qₑ

Substituting the given values;

Vₑ = (1.6605 × 10^−27 kg × (2.9979 × 10^8 m/s)^2)/1.602 1766× 10^-19

Vₑ = 9.314569 × 10^8 eV

Vₑ = 931.5 ×10^6 eV

Vₑ = 931.5 MeV

A ball with 100 J of PE is released from a height of 10 m. What will be the KE of the ball at 5
harkovskaia [24]

Answer:

The kinetic energy is: 50[J]

Explanation:

The ball is having a potential energy of 100 [J], therefore

PE = [J]

The elevation is 10 [m], and at this point the ball is having only potential energy, the kinetic energy is zero.

E_{p} =m*g*h\\where:\\g= gravity[m/s^{2} ]\\m = mass [kg]\\m= \frac{E_{p} }{g*h}\\ m= \frac{100}{9.81*10}\\\\m= 1.01[kg]\\\\

In the moment when the ball starts to fall, it will lose potential energy and the potential energy will be transforme in kinetic energy.

When the elevation is 5 [m], we have a potential energy of

P_{e} =m*g*h\\P_{e} =1.01*9.81*5\\\\P_{e} = 50 [J]\\

This energy is equal to the kinetic energy, therefore

Ke= 50 [J]

Which is the correct answer?
Nezavi [6.7K]

Answer:

Point A

Explanation:

The work done by stretching or compressing a spring is given by E=1/2kx²

The potential energy is numerically equal to the work done.

This means that the higher the bigger the value of the extension, x, the higher the energy contained.

In this scenario the modulus of x is considered.

Among the given values of x the modulus of -5 is the largest.

thus it gives the highest value of energy.
