D=Vot+1/2at^2
In this case, there is no initial y velocity so the term Vot=0 so d=1/2at^2
acceleration=acceleration due to gravity=-9.8m/s^2
It falls - 22cm or -0.22m
We have - 0.22=1/2(-9.8)t^2
t^2=(-0.44)/(-9.8)
t=sqrt[0.44/9.8]
Answer:
The options are approximations of the exact answers:
A) 
B) 
C) 
D) Toward the inner wall
E) 
Explanation:
A) The electric field in a parallel plate capacitor is given by the formula
, where
and in our case
and, for air,
, so we have:

B) The K+ ion has one elemental charge excess, so its charge is
, and the force a charge experiments under an electric field E is given by F=qE, so we have:

C) The potential difference between two points separated a distance d under an uniform electric potential E is given by
, so we have:

D) The electic field goes from positive to negative charges, so it goes towards the inner wall.
E) The work done by an electric field through a potential difference
on a charge Q is
, and is equal to the kinetic energy imparted on it, so we have:

Answer:
Fats.
Explanation:
A fat molecule which is called a Triglyceride consists of two main components which are glycerol and 3 fatty acids. Fats are solids and oils are liquids at room temperature. They also include saturated and unsaturated fats.
Cells store energy for long-term use in the form of lipids called fats which provides insulation from the environment for plants and animals.
1) Mass won't change (
kg).
2) 
3) 
4) 
As
and
are constants,
. In other words, the more massive the object is, the bigger its gravitational acceleration (obviously, the lighter the object is, the lesser its gravitational acceleration)
Answer:

Explanation:
The minimum height of a space shuttle from the surface of the earth is 304 kilometers.
So according to this data we calculate the value to g at that height.
We have the formula:

where:
g' = the acceleration due to gravity at the given height 'h' above the earth
R = radius of the earth
g = the acceleration due to gravity at the surface of the earth
Now, using eq. (1)
