according to conservation of momentum , total sum of momentum of the objects taking part in a collision is same before and after the collision.

Total momentum before collision = Total momentum after the collision

when a cue ball moving at velocity 1.5 m/s hits a billiard ball , transfer of momentum takes place between the balls such that total sum of momentum of cue ball and billiard ball remain same before and after the collision.

hence we say that the momentum is conserved.

Air flows into a jet engine at 70 lbm/s, and fuel also enters the engine at a steady rate. The exhaust gases, having a density o
Andrews [41]

Answer:

1387908 lbm/h

Explanation:

Air flowing into jet engine = 70 lbm/s

ρ = Exhaust gas density = 0.1 lbm/ft³

r = Radius of exit with a circular cross section = 1 ft

v = Exhaust gas velocity = 1450 ft/s

Exhaust gas mass (flow rate)= Air flowing into jet engine + Fuel

Q = (70+x) lbm/s

Area of exit with a circular cross section = π×r² = π×1²= π m²

Now from energy balance

Q = ρ×A×v

⇒70+x = 0.1×π×1450

⇒70+x = 455.53

⇒ x = 455.53-70

⇒ x = 385.53 lbm/s

∴ Mass of fuel which is supplied to the engine each minute is 1387908 lbm/h

What are the directions of movement for the Sagittarius, frontal, transverse planes ?
Dima020 [189]

Answer:

Squats involve flexion (forward motion) and extension (backward on the way up), so would fit into the sagittal plane. Frontal plane motion would include leaning from left to right as in sidebends and lateral raises, or perhaps you might picture jumping jacks for a good image of movement along the frontal plane.

svet-max [94.6K]

Answer:

C: As a consequence of growing, organisms cause a greater increase in entropy in their environment than the decrease in entropy associated with their growth.

Explanation:

Particularly, whole organisms on the earth obtain the energy from sunlight, and the sun is undertake an vast increase in entropy that simply compensates for the reducing entropy of living things on this small planet.

Contact metamorphism occurs over a localized area when magma moves into the crust. true or false
GenaCL600 [577]

Answer:

TRUE

Explanation:

When the hot and less dense magma rises up towards the surface, the country rocks are heated due to the increasing temperature of the magma. This results in the formation of an aureole that surrounds the intruded magma body. This aureole is commonly known as the metamorphic aureole and contact metamorphism occurs in this area. This type of process occurs at a comparatively smaller area, and where there is a high temperature and low-pressure condition. For example, Hornfels and Marble.

Thus, the above-given statement is True.
