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.
current, the flow of electrons make the current
The type of cell that does NOT use cell division to replicate is the reproductive.
If I'm wrong then, well.. at least i tried.
Answer:
10.4 m/s
Explanation:
The problem can be solved by using the following SUVAT equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
For the diver in the problem, we have:
is the initial velocity (positive because it is upward)
is the acceleration of gravity (negative because it is downward)
By substituting t = 1.7 s, we find the velocity when the diver reaches the water:
And the negative sign means that the direction is downward: so, the speed is 10.4 m/s.
Answer:
C. 
and 
.
Explanation:
The two hockey pucks travels in opposite sides with velocities of same magnitude, by definitions of linear momentum and translational kinetic energy:
Linear momentum
<em>Hockey puck A</em>
(1)
<em>Hockey puck B</em>
(2)
Translational kinetic energy
<em>Hockey puck A</em>
(3)
<em>Hockey puck B</em>
(4)
Hence, the correct answer is C.
