1. A body is in motion when it changes its position at a certain time/duration.
2. Speed is related to how fast a body is moving.
3. Speed means that a body is moving and covering distance at a certain time.
4. Speed<span> is the distance traveled by an object where as, </span>velocity<span> is distance traveled by an object per unit time in a particular direction. </span>
5. Velocity is the rate of change of distance or direction of a body with respect to time.
Transformation of energy, because energy cannot be created or destroyed
I am going to say
C. Energy contained in the nucleus of an atom
Answer:
x₂ = 1.33 m
Explanation:
For this exercise we must use the rotational equilibrium condition, where the counterclockwise rotations are positive and the zero of the reference system is placed at the turning point on the wall
Στ = 0
W₁ x₁ - W₂ x₂ = 0
where W₁ is the weight of the woman, W₂ the weight of the table.
Let's find the distances.
Since the table is homogeneous, its center of mass coincides with its geometric center, measured at zero.
x₁ = 2.5 -1.5 = 1 m
The distance of the person is x₂ measured from the turning point, at the point where the board begins to turn the girl must be on the left side so her torque must be negative
x₂ = 
let's calculate
x₂ = 
x₂ = 1.33 m
Answer:
This question is an example of Boyle's gas law which states that the pressure of a given mass of a gas is inversely proportional to its volume at a constant temperature. The formula for this gas law is:
P1·V1 = P2·V2
P1 = initial pressure = 1.7 atm
V1 = initial volume = 4.25 L
P2 = final pressure = 2.4 atm
V2 = final volume = ?
Rearrange the formula to isolate V2. Substitute the known data and solve.
V2 = P1·V1/P2
V2 = 1.7 atm·4.25 L/2.4 atm = 3.0 L to two significant figures
The new volume will be ~3.0 L.
