Answer:
Part a)
V = 18.16 V
Part b)
Part c)
P = 672 Watt
Part d)
V = 5.84 V
Part e)
Explanation:
Part a)
When battery is in charging mode
then the potential difference at the terminal of the cell is more than its EMF and it is given as
here we have
now we have
Part b)
Rate of energy dissipation inside the battery is the energy across internal resistance
so it is given as
Part c)
Rate of energy conversion into EMF is given as
Now battery is giving current to other circuit so now it is discharging
now we have
Part d)
Part e)
now the rate of energy dissipation is given as
Well she drove 30 more miles to the east than the west but I don’t understand what u are asking
The distance traveled by the hockey player is 0.025 m.
<h3>The principle of conservation of linear momentum;</h3>
- The principle of conservation of linear momentum states that, the total momentum of an isolated system is always conserved.
The final velocity of the hockey play is calculated by applying the principle of conservation of linear momentum;
The time taken for the puck to reach 15 m is calculated as follows;
The distance traveled by the hockey player at the calculated time is;

Answer:
Hits per second=199 hit/s
Explanation:
#Given the angular velocity, , radius of the record and the distance between any two successive bumps on the groove as .
The linear speed of the record in meters per second is:
#From above, if the bumps are uniformly separated by 1m, then the rate at which they hit the stylus is:
Hence the bumps hit the stylus at around 199hit/s
Answer:
Yes, it is reasonable to neglect it.
Explanation:
Hello,
In this case, a single molecule of oxygen weights 32 g (diatomic oxygen) thus, the mass of kilograms is (consider Avogadro's number):
After that, we compute the potential energy 1.00 m above the reference point:
Then, we compute the average kinetic energy at the specified temperature:
Whereas stands for the Avogadro's number for which we have:
In such a way, since the average kinetic energy energy is about 12000 times higher than the potential energy, it turns out reasonable to neglect the potential energy.
Regards.
