How do you work out instantaneous speed?

Alik [6]

To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.

Y_Kistochka [10]

Answer:

Explanation:

Given

Original volume V1=30cm^3 converting to L

=30/1000=0.03L

Constant pressure P= 648 tors

Converting to atm; 648 tors*1atm/760 torr=0.853 atm

Work=984J= 984**1L/101.33=9.7L.atm

Note before

W= -P(Vfinal-Vinitial)

-9.7/0.853+0.03L=11.68L

denpristay [2]

Answer:

The tension in string P is 25 N, while that of Q is 85 N.

Explanation:

Considering the conditions for equilibrium,

i. Total upward force = Total downward force

$T_{P}$ + $T_{Q}$ = 110 N

ii. Taking moment about P,

clockwise moment = anticlockwise moment

110 × (2.5 - 0.8) = $T_{Q}$ × (3 - 0.8)

110 × 1.7 = $T_{Q}$ × 2.2

187 = 2.2 $T_{Q}$

$T_{Q}$ = $\frac{187}{2.2}$

$T_{Q}$ = 85 N

From the first condition,

$T_{P}$ + $T_{Q}$ = 110 N

$T_{P}$ + 85 N = 110 N

$T_{P}$ = 110 - 85

$T_{P}$ 25 N

Therefore, the tension in string P is 25 N while that of Q is 85 N.
