Drag each tile to the correct location.

Lady_Fox [76]

The order of the location of each process in the carbon cycle are as follows;

Ingestion → Decomposition → Fossilization → Combustion

Reasons:

Ingestion; During the ingestion process, the products of the direct Sunlight and photosynthesis, which

are energy rich chemical substances are ingested by herbivores.

Decomposition; The plants and animals die and undergo decomposition.

Fossilization; A long period the decomposed plants and animals manifest

into hard petrified materials, with their parts transformed to fossils.

Combustion; The remains of plants and animals, subjected to heat and

pressure due to compression, as when as bacteria decomposition that

removes several other elements, leaving a carbon and hydrogen rich

sludge that can be processed into fuel used for combustion. The

combustion process produces carbon dioxide which restarts the cycle.

slader A transcontinental flight of 4890 km is scheduled to take 40 min longer westward than eastward. The airspeed of the airpl

11111nata11111 [884]

Answer:

$v_{s}=65.2km/h$

Explanation:

Given data

Flight distance S=4890 km

Time difference Δt=t₂-t₁=40 min

Air speed of plane=980 km/h

To find

Speed of jet stream

Solution

When moving in the same direction as the jet stream time taken as t₁=d/(v+vs),v is velocity of plane and vs is velocity of plane

While moving in opposite direction t₂=d/(v+vs)

$t_{2}-t_{1}=\frac{d}{(v-v_{s}) } - \frac{d}{(v+v_{s}) }\\t_{2}-t_{1}=\frac{d(v+v_{s})-d(v-v_{s})}{(v-v_{s})(v+v_{s})} \\t_{2}-t_{1}=\frac{2dv_{s}}{(v)^{2} -(v_{s})^{2} }\\0.666667h=\frac{2(4890km)v_{s}}{(980km/h)^{2} -(v_{s})^{2} }\\0.666667((980km/h)^{2} -(v_{s})^{2})=9780v_{s}\\640267-0.666667(v_{s})^{2}-9780v_{s}=0\\0.666667(v_{s})^{2}+9780v_{s}-640267=0$

Apply quadratic formula to solve for vs

$v_{s}=65.2km/h$

Tiger woods hits 45.0-gram golf ball, giving it a speed of 75.0 m/sec. What momentum has tiger woods given to the golf ball

valkas [14]

M = 45.0 g in Kg 0.045 Kg

speed = 75.0 m/sec

Δp = m * speed

Δp = 0.045* 75.0

Δp = 3.375 kg.m/s

hope this helps!

How can u prove that there is an electric field

zimovet [89]

Explanation:

By introducing a particle of one positive coulomb between the electric plates, the particle experience a force against the electrostatic forces, proving that it is in an electric field

The force experienced by this particle is known as Electric Field Intensity  denoted by E and it is given by

$k \times \frac{q {}^{2} }{r}$

where, k is constant =

$9 \times {10}^{9}$

q is the charge magnitude on the particle

r is the separation of the particles
