Answer: two electrons
Explanation: The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons. Each principal energy level above the first contains one s orbital and three p orbitals. A set of three p orbitals, called the p sublevel, can hold a maximum of six electrons.

Explanation:
Answer:
in simple harmonic motion, the formula for finding amplitude is:
a = -ω^2 x
where, a=amplitude, ω= angular frequency, x= Displacement
Explanation:
Answer:
Box A
Explanation:
Let mass of each wooden box =m
Density of box A=
Density of box B =

Density,


Density of inversely proportional to volume.
The volume of box with smaller density is larger than the volume of box with large density.

When the boxes are submerged under water.
Then, the buoyant force=
Where V=Volume of displace fluid.
Density of fluid
Buoyant force of box A=
Buoyant force of box B=
Force=Buoyant force


Acceleration is directly proportional to volume.
Therefore,the box with large volume has greater acceleration.
Hence, the box A has greater acceleration.
kinematic equation
v^2=u^2+2*a*s
7.4^2=8^2-2*5.6^2*width
(7.4^2-64)/(2*5.6^2)=-width
