P2o3 is <span>diphosphorus trioxide.
Add water and you get phosphoric acid</span>
Because of conservation of energy, ep is equal to ek.
at that point ep=ek
the kinetic energy would be 32,781J
Answer:
5 liters.
Explanation:
We are being given the expression
V = 0.041h - 0.018A - 2.69
The height h is 165 cm.
The Age A is 65 years old.
So we replace the values of h and A in the equation given:
V = 0.041 * 165 + 0.018 * 65 - 2.69 = 5.245 liters.
Rounding, we notice that 5.245 liters is closer to 5 than 6. So the answer would be 5 liters.
Answer:
Explanation:
A magnet has a magnetic field around it which originates at the north pole and enters through the south pole.
In a magnet, like poles will repel each other and unlike poles will attract.
- The north pole of one magnet will repel another north pole of another magnet.
- North pole of one magnet will attract the south pole of another magnet.
- This is the law of attraction and repulsion of magnet.
Answer:
2.92 x 10¹² electrons
Explanation:
given,
distance between two plastic ball, r = 17 cm
r = 0.17 m
Force of attraction = F = 68 mN
F = 0.068 N
number of electron transferred from one ball to another.
using Coulomb Force equation
q² = 2.1835 x 10⁻¹³
q = 4.67 x 10⁻⁷ C
now, number of electron
e is the charge of electron which is equal to 1.6 x 10⁻¹⁹ C
N = 2.92 x 10¹² electrons
electrons were transferred from one ball to the other is 2.92 x 10¹²
