Answer:
Explanation:
1) Moc to wskaźnik czasu pracy w stosunku do czasu.
Moc = czas pracy / czas
Czas pracy = moc * czas
Podana moc = 200 kW = 200 000 Watów
Czas = 1,5 godziny = 1,5 * 3600 = 5400 sekund
workdone = 200 000/5400
Obróbka = 37,04 dżula
2) Moc = Gotowe / czas
Od zakończenia = Siła * Odległość
Moc = siła * Odległość / czas
Podana siła = 300 N.
Odległość = 2,5 m
czas = 0,5 min = 0,5 * 60 = 30 sekund
Moc = 300 * 2,5 / 30
Moc = 25 watów
3) Moc = Gotowe / czas
Czas potrzebny = praca / moc
Biorąc pod uwagę pracę wykonaną przez ciągnik = 10 MJ = 10 * 10 ^ 6 Dżuli
Moc = 100 kW = 100 000 watów
Czas wzięty = 10 ^ 7/10 ^ 5
Zajęty czas = 100 sekund

An electron has a negative charge so losing a charge of -1 from an uncharged, or neutral, atom will leave an ion with a positive charge.
Answer:
Explanation:
Let the charge on proton be q .
energy gain by proton in a field having potential difference of V₀
= V₀ q
Due to gain of energy , its kinetic energy becomes 1/2 m v₀²
where m is mass and v₀ is velocity of proton
V₀ q = 1/2 m v₀²
In the second case , gain of energy in electrical field
= 2 V₀q , if v be the velocity gained in the second case
2 V₀q = 1/2 m v²
1/2 m v² = 2 V₀q = 2 x 1/2 m v₀²
mv² = 2 m v₀²
v = √2 v₀
The maximum acceleration the truck can have so that the refrigerator does not tip over is 4.15 m/s².
<h3>What will be the maximum acceleration of the truck to avoid tipping over?</h3>
The maximum acceleration is obtained by taking clockwise moments about the tipping point of rotation.
Clockwise moment = Anticlockwise moment
Ft * 1.58 m = F * 0.67 m
where
- Ft is tipping force = mass * acceleration, a
- F is weight = mass * acceleration due to gravity, g
m * a * 1.58 = m * 9.81 * 0.67
a = 4.15 m/s²
The maximum acceleration the truck can have so that the refrigerator does not tip over is 4.15 m/s².
In conclusion, the acceleration of the truck is found by taking moments about the tipping point.

Answer: Black hole.
Explanation:
As the massive star "compacts" under its own gravity, it triggers a massive supernova, after this point the remains of the star can become a neutron star, which is a very compact star made primarily, as the name says, of neutrons. The other possibility is a black hole, which is a finite region of space wherein it's interior there is a big concentration of mass, which creates a gravitational field strong enough that there is no particle that can escape it.
