Answer:

At constant pressure

Explanation:

Enthalpy of a system may be defined as the system's internal energy in addition to the product of the volume and pressure of the system.

It can be regarded as the system's capacity of heat transfer and to do non- mechanical work.

The enthalpy of the system at constant pressure gives the amount of heat or energy that is either absorbed by the system or released by the system.

A proton and an electron are released from rest in the center of a capacitor.
Sunny_sXe [5.5K]

Answer:

a)  equal 1, b) less than 1

Explanation:

a) the electric force is given by

         Fe = q E

The charge of the electron and proton has the same value, that of the proton is positive and that of the electron is negative

Proton

        Fp = qE

Electron

         Fe = - q E

         Fp / Fe = -1

If we do not take into account the sign the relationship is equal to one (1)

b) to calculate the force we use Newton's second law

           F = ma

           qE = m a

           a = q E / m

The mass of the proton much greater than the mass of the electron

          ap = q E / m_{p}

          ae = - q E /  m_{e}

          ap / ae =  m_{e} /  m_{p} =  m_{e}/1600  m_{e} =1/1600

 It is much smaller than 1

Tim jogs a distance of 7.2 km to the west. Then he turns south and jogs 1.4 km. West is the resultant if Tim's jog back to the b
vesna_86 [32]

Answer:

Explanation:

If Tim jogs a distance of 7.2 km to the west and then he turns south and jogs 1.4 km, the resultant displacement of Tim is calculated using the pythagoras theorem as shown;

R² = 7.2²+1.4²

R² = 51.84+1.96

R² = 53.8

R = √53.8

R = 7.33 km

Hence  the resultant of Tim's jog back to the beginning is 7.33km

What phenomenon causes the fuzzy image? What kind of lens is used to correct this, and how is it corrected?
Amiraneli [1.4K]

Sample Response: This phenomenon is called chromatic aberration. This happens when light of different wavelengths focuses at different points. A converging lens is used to help light of different wavelengths focuses at a common point.
