A plane has a take off speed of 1 point

Physics
1 answer:
oksian1 [2.3K]3 years ago
4 0

Answer:

Acceleration = 1.85m/s²

Explanation:

Given the following data;

Final velocity = 300km/h to m/s = 300*1000/3600 = 83.33m/s

Time = 45 seconds

Since the plane started from rest, initial velocity is equal to 0m/s.

To find the acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Mathematically, acceleration is given by the equation;

Acceleration (a) = \frac{final \; velocity  -  initial \; velocity}{time}

Where,

a is acceleration measured in ms^{-2}

v and u is final and initial velocity respectively, measured in ms^{-1}

t is time measured in seconds.

Substituting into the equation, we have;

Acceleration = (83.33 - 0)/45

Acceleration = 83.33/45

Acceleration = 1.85m/s²

Therefore, the acceleration of the plane is 1.85m/s².

A train travels 57 kilometers in 3 hours, and then 87 kilometers in 2 hours. What is its average speed? km/hr
skad [1K]
Average speed (v) = total distance(d) / total time (t)
d = 57 + 87km = 144km
t = 2 + 3hrs = 5hrs
v = d÷t = 144÷5 = 28.8km/hr

How do natural gas and crude oil compare as energy resources?
Mazyrski [523]

Answer:

Crude oil and natural gas are both energy commodities. As such, we use these fuels to heat and cool our homes or supply other energy needs. The price relationship between crude oil and natural gas is an inter-commodity spread, in which the prices between the two change in relation to each other.

Historically, in an inter-commodity spread, when one becomes more expensive, the other will be more desirable for consumers because of the lower prices and higher supply.

Many companies that produce crude oil also produce natural gas. Natural gas and crude oil exploration and production are often related because the release and capture of natural gas can occur during the oil drilling process.

The relationship between crude oil and natural gas changed around the turn of the 21st century due to the discovery of more natural gas reserves in the United States.

Huge natural gas reserves, previously undiscovered in the Marcellus and Utica shale regions of the U.S., altered the price relationship between these two energy commodities, lowering the price of natural gas in the U.S. while the price of oil continued to rise between 2000 and 2014.

Attributed to slowing growth of emerging economies and a reduction in oil demand, a drastic drop in the price of crude oil occurred in late 2014, continuing through early 2016. By 2018, the price of crude oil crept back up to over $70 per barrel. However, due to the coronavirus in 2020 almost halting demand for oil, crude oil prices dropped to historic lows, while natural gas dropped a little, but held pretty steady.

Light is described as having a dual wave-particle nature. Which piece of evidence provides support for the model of light as a w
S_A_V [24]

Answer:

The evidence that supports the wave particle nature of light as a wave is:

"Light reflects when it hits a surface."

Explanation:

Light exhibit wave-particle duality. This means, in some cases the properties of light are just like a wave and in other cases it behaves as particles.

The properties like reflection or refraction from a surface are attributed as properties of waves. The phenomena of interference and diffraction also fall in this category.

Therefore, from the given options, the only option that supports the evidence of light as a wave is "Light reflects when it hits a surface", as reflection is entirely the property of a wave.
