Answer:
Explanation:
Given that
F(x) = (2.00 N/m) x +(1.00 N/m3) x3.
Which can be written as
F(x) = 2x +x³ N/m
Potential energy from x=1 to x=2
P.E is given as
P.E=∫F(x)dx
P.E=∫2x+x³ dx. From x=1 to x=2
P.E= 2x²/2 + x⁴/4 from x=1 to x=2
P.E= x² + x⁴/4 from x=1 to x=2
P.E=(2²+2⁴/4)-(1² +1⁴/4)
P.E=(4+4)-(1+1/4)
P.E, =8-5/4
P.E=27/4
P.E=6.75J
Since it is moving from lower position to upper position, then P.E should be negative
P.E = - 6.75J
The only thing about a wave that has units of time is the wave's <em>PERIOD</em>.
Answer:
36 m³
Explanation:
From gas laws, at a constant temperature, the product of volume and pressure are directly proportional hence expressed as p1v1=p2v2 where p is pressure while v represent volume. Subscripts 1 and 2 represent the initial and respectively. Making v2 the subject then
Substituting 120 kpa for P1, 12m³ for V1 and 40 kpa for p2 then
Therefore, the volume will be 36 m³
