Which correctly compares how coal and oil are formed? A. Coal results from the compressed remains of marine organisms, while oil

is the compressed remains of plants. Both are made due to pressure and heat under buried layers of rock over millions of years. B. Coal results from the compressed remains of plant matter, while oil is the compressed remains of marine organisms. Coal was made due to pressure and heat under buried layers of rock over millions of years, while oil was made by heating the compressed remains from magma underneath. C. Coal results from the compressed remains of plant matter, while oil is the compressed remains of marine organisms. Oil was made due to pressure and heat under buried layers of rock over millions of years, while coal was made by heating the compressed remains from magma underneath. D. Coal results from the compressed remains of plant matter, while oil is the compressed remains of marine organisms. Both are made due to pressure and heat under buried layers of rock over millions of years.

Whats the word for when "velocity equals 0 and direction changes" Its 14 letters, and I have _ _ _ _ i _ _ _ _ _ h_ i _ _ t
alisha [4.7K]

Answer:

Maximum Height

Explanation:

The maximum height is the highest point reached by a projected body. At this point, final velocity, v of the body is equal to 0; because upward motion is at its peak and the body start to fall again.

Hence, final velocity v is always 0 at this maximum point and the direction of motion changes from upward to downward.

Final velocity at this maximum height is zero because of the directional change experied by the object and the fact that upward motion of the body terminates at this point.

AlekseyPX

Explanation:

Initial speed of the incident water stream, u = 16 m/s

Final speed of the exiting water stream, v = -16 m/s

The mass of water per second that strikes the blade is 48.0 kg/s.

We need to find the magnitude of the average force exerted on the water by the blade. The force acting on an object is given by :

F=\dfrac{m(v-u)}{t}

Here, \dfrac{m}{t}=48\ kg/s

F=48\times (-16-16)\ N\\\\F=-1536\ N\\\\|F|=1536\ N

So, the magnitude of the average force exerted on the water by the blade is 1536 N.

The 25-mph zone is 150 yards long. How much time did the student save (in seconds) by speeding past the school
VikaD [51]

Answer:

Time = 12.27seconds

Explanation:

Given

Speed = 25miles/hour

Distance = 150 yards = 150(0.000568182)miles

Distance (in miles) = 0.0852273miles

Get the time

Speed = Distance/Time

Time = Distance/Speed

Time = 0.0852273/25

Time = 0.0034hours

Time = 0.0034 * 3600secs

Time = 12.27seconds

What is the average velocity of atoms in 1.00 mol of neon (a monatomic gas) at 465 K? For m, use 0.0202 kg.
TiliK225 [7]

Answer: 757m/s

Explanation:

Given the following :

Mole of neon gas = 1.00 mol

Temperature = 465k

Mass = 0.0202kg

Using the ideal gas equation. For calculating the average kinetic energy molecule :

0.5(mv^2) = 3/2 nRt

Where ;

M = mass, V = volume. R = gas constant(8.31 jK-1 mol-1, t = temperature in Kelvin, n = number of moles

Plugging our values

0.5(0.0202 × v^2) = 3/2 (1 × 8.31 × 465)

0.0101 v^2 = 5796.225

v^2 = 5796.225 / 0.0101

v^2 = 573883.66

v = √573883.66

v = 757.55109m/s

v = 757m/s
