How would you determine the volume of an irregularly shaped object such as a paper clip?

zheka24 [161]

Explanation:

Take a measuring cylinder and fill it with a certain amount of water. Measure this amount of water.

Place the paper clip in the filled measuring cylinder. You will notice that the water level has gone up. When we place the paper clip in the cylinder the volume of the paper clip gets added to the volume that was present in the cylinder.

The volume of the paper clip will be the final volume of water with the paper clip - The initial volume of water without the paper clip.

Any irregularly shaped object's volume can be determined by this method.

A jet aircraft is traveling at 262 m/s in horizontal flight. The engine takes in air at a rate of 85.9 kg/s and burns fuel at a

Fittoniya [83]

Answer:

$F_T=60132.52N$

$P=15814852.76W$

Explanation:

From the question we are told that

Velocity of aircraft $V=263m/s$

Engine air intake rate $\triangle M_a=85.9kg/s$

Fuel burn rate $\triangle M_f =3.92kg/s$

Velocity of exhaust gas $V_e =921m/s$

Generally the Mass change rate of Rocket is mathematically given by

$\triangle M = \triangle M_a+\triangle M_f$

$\triangle M= 85.9+3.92$

$\triangle M=89.82kg/s$

Generally the Trust of the rocket is given mathematically by

$F_T=(\triangle M *V_e)-(dM_a/dt)*(V)$

$F_T=(89.82 *921)-(85.9)*(263)$

$F_T=60132.52N$

Generally the Rocket's delivered power is mathematically given by

Delivered power P

$P=V*F_T$

$P=263*60132.52N$

$P=15814852.76W.$
