Answer:
8.8 cm
31.422 cm/s
Explanation:
m = Mass of block = 0.6 kg
k = Spring constant = 15 N/m
x = Compression of spring
v = Velocity of block
A = Amplitude
As the energy of the system is conserved we have
Amplitude of the oscillations is 8.8 cm
At x = 0.7 A
Again, as the energy of the system is conserved we have
The block's speed is 31.422 cm/s
Answer:
C. L/T
Explanation:
This is dimension of velocity because
Acceleration = velocity /time
Then,
Velocity= acceleration*time
6/3 Li is more stable due to it being composed of more than two stable isotopes.
Answer:
- <u>The electronic geometry of the different compounds:</u>
The over all geometry or structure of the compound is greatly effected by the number of lone pair electrons on its central atom, as there are a number of free or non- bonding electrons present inside the structure of the compound that effects the over all structure of the compound.
Explanation:
A- SO₂ and BF₃ has 3 lone pair of electrons and it has a trigonal planer geometrical shape, due to the presence of the 3 different regions or points of electronic density on its central atom.
B-NH₃ and CH₄ have the four different zones or regions due to having the very concrete or strong electronic density on its central atom. As, the shape of the molecules itself tends to be more tetrahedral in its geometric form or shape.
C- PCL₅ and PF₅ are the two compounds having the 5 different regions of electronic density. As, the over all geometric shape or structure of the compound is more trigonal Bi-pyramidal in total, as there are the lone pair of electrons on the central atom which makes the whole structure of the compound.
This phenomenon is as a result of static friction created by the tumbling clothes. Static friction results from the rubbing together of two or mores objects or body and electrons are stripped from one surface of the clothes more than the other. This creates an electrostatic force of attractions between the positive charges on one cloth and the negative charges on the other cloth.(unlike charges attract).
