Answer:
The resulting velocity of marble B after the collision is 0.96 m/s.
Explanation:
Mass of marble A ,
Initial velocity of the marble A,
Mass of marble B,
Initial velocity of the marble B,
final velocity of the marble A,
final velocity of the marble B,
Applying law of conservation of mass:
The resulting velocity of marble B after the collision is 0.96 m/s.
Answer:
The total number of valence electrons per atom does not change. It remains at 7 (as opposed to 1 in the options.)
Explanation:
The periodic table organizes elements with the same number of valence electrons in the same column.
All the halogens (F, Cl, Br, etc.) are found in the same column (the second column from the right) on the periodic table. The all have the same number of valence electrons per atom.
All elements in the right-most column (the one with all the noble gas elements) contain 8 valence electrons per atom (a full valence shell.) Since the halogens are to the left of the noble gas elements by only one place, each would contain valence electrons.
Answer:
Explanation:
E = Energy
T = Time
Power is given by the equation
For first case
For second case
For third case
The rank of power would be
Answer:
the velocity of the point P located on the horizontal diameter of the wheel at t = 1.4 s is
Explanation:
The free-body diagram below shows the interpretation of the question; from the diagram , the wheel that is rolling in a clockwise directio will have two velocities at point P;
- the peripheral velocity that is directed downward along the y-axis
- the linear velocity that is directed along the x-axis
Now;
Also,
where (angular velocity) =
∴ the velocity of the point P located on the horizontal diameter of the wheel at t = 1.4 s is
