Answer:
Electronegative atom will create a stronger negative charge is true.
Explanation:
Given that,
Electronegativity affects the strength of intermolecular forces.
We know that,
Electronegativity :
Electronegativity is a ability of an atom, shared electron to itself.
In periodic table,
When we move left to right in period then the electronegativity increases.
When we move up to down in a group then the electronegativity decreases.
We know that,
The intermolecular forces are dipole-dipole interactions which is the strongest intermolecular force of attraction.
If the electronegativity of atom is more, then the atom gain negative charge.
When the attraction force is more in atoms then the electronegative will be more.
Hence, Electronegative atom will create a stronger negative charge is true.
Answer:
From what I know they postponed the movies that were suppose to come out.
Added potential energy = (mass) x (gravity) x (height)
or
Added potential energy = (weight) x (added height)
If you need to lift a 15N box 3m straight up, you have to increase its potential energy by (15 N) x (3 m) = 45 Joules .
Where is that added potential energy supposed to come from ? You could use an electric winch, a steam engine, a gasoline-powered motor, thousands of hamsters running on little treadmills that are are connected to the main pulley somehow, or your own arm muscles. But howEVER you do it, you have to provide <em>45 Joules</em> of WORK in order to increase the potential energy of the box by just that much.
Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
AnswerThe current through a toaster connected to a 120-V source is 8.0 A. What power is given off by the toaster? p= 8.0 A : 120V (p=960 W Page 2 7. The resistance of an electric stove eleinent at operating temperature is 11 12.
