Answer:

0.125 atm

Explanation:

From the question,

Applying boyles law

PV = P'V'................................. Equation 1

Where P = Initial pressure, V = Initial volume, P' = Final pressure, V' = final Volume.

make P' the subject of the equation

P' = PV/V'............................. Equation 2

Given: P = 97.5 atm, V = 90 mL = 0.09 L, V' = 70 L.

Substitute these values into equation 2

P' = 97.5×0.09/70

P' = 0.125 atm

Answer:

Forces acting on an object may be balanced or unbalanced. When the forces  acting on an object have <u>equal</u> strength and act in opposite directions, they  are <u>balanced</u>. These forces cancel out one another, and the <u>motion</u> of the  object does not <u>change</u>.  When the forces acting on an object are <u>unbalanced</u>, they do not cancel out  one another. An unbalanced force acting on an object results in the object’s  motion <u>changing</u>. The object may change its <u>speed</u> (speed up or slow down), or it may change its <u>direction</u>.  <u>Friction</u> is a force that resists the motion or the tendency toward motion  between two objects in contact with each other.  <u>Gravity</u> is a force that pulls objects toward one another. For example, Earth  pulls all objects toward it.
