Answer:
In ionic compounds, electrons are transferred between atoms of different elements ... For example, two hydrogen atoms bond covalently to form an H2 molecule; each ... is released when one mole of H2 molecules forms from two moles of H atoms: ... atom in each pair is more electronegative: (a) N or P. (b) N or Ge. (c) S or F.
Explanation:
Force and distance is the main criteria for the movement of the object. The work of the object can be defined as the ‘product’ of the force and distance.
Answer:
M1 = 16.9 mA
M2 = 0 A
Explanation:
As the ratio of the two sets of series resistors is almost exactly identical, there is no voltage difference across M2 to cause current flow
269/(269 + 439) = 0.3799...
500/(500 + 815) = 0.38022
M2 = 0
M1 sees only the current flowing through the far left resistors in series
A = V/R = 12/(269 + 439) = 0.016949... ≈ 16.9 mA
Answer:
640 J
Explanation:
ΔKE = KE − KE₀
ΔKE = ½ mv² − ½ mv₀²
ΔKE = ½ m (v² − v₀²)
ΔKE = ½ (80 kg) ((5 m/s)² − (3 m/s)²)
ΔKE = 640 J
Her kinetic energy increases by 640 J, so she does 640 J of work.
The weight is the force of gravity acting on the object. So assuming it’s on earth, 12(9.81) also, F(weight in Newtons)=mass( in kg)acceleration (due to gravity)
