The <span>change in internal energy of the system is 10520 J

 </span>From the first law of thermodynamics, the change in internal energy is equal to work done by the system subtracted from the heat added to the system.

i.e.ΔU = Q - W 
Now, as per question, <span>A system uses 2,380 J of energy to do work as 12,900 J of heat are added to the system.

Thus, </span>ΔU = 12900 - 2380 = 10,520 J

A 12 volt battery in a motor vehicle is capable of supplying the starter motor with 150 A. It is noticed that the terminal volta
qwelly [4]

Answer:0.0133 \Omega

Explanation:

Given

Voltage=12 V

Current(I)=150 A

V_{terminal}=10 V

r_{internal}=\frac{\Delta V}{I}

r_{internal}=\frac{12-10}{150}

r_{internal}=\frac{2}{150}=0.0133 \Omega

Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating charge th
statuscvo [17]

Answer:

 P /K = 1,997 10⁻³⁶  s⁻¹

Explanation:

For this exercise let's start by finding the radiation emitted from the accelerator

       \frac{dE}{dt} = \frac{q^{2} a^{2} }{6\pi  \epsilon_{o} c^{2}    }

the radius of the orbit is the radius of the accelerator a = r = 0.530 m

let's calculate

       \frac{dE}{dt} = [(1.6 10⁻¹⁹)² 0.530²] / [6π 8.85 10⁻¹² (3 108)³]

      P= \frac{dE}{dt}= 1.597 10⁻⁵⁴ W

Now let's reduce the kinetic energy to SI units

       K = 5.0 10⁶ eV (1.6 10⁻¹⁹ J / 1 eV) = 8.0 10⁻¹⁹ J

the fraction of energy emitted is

      P / K = 1.597 10⁻⁵⁴ / 8.0 10⁻¹⁹

      P /K = 1,997 10⁻³⁶  s⁻¹
