Answer: Fluorinated gases (F-gases) are man-made gases that can stay in the atmosphere for centuries and contribute to a global greenhouse effect. this is extremely bad for the earth and is causing downpour on our plants and animals. Why would we creat gases we can not get rid of its ver diapointing
Answer:
Explanation:
His top speed is a blip that occurs for less than the full time he was out. Below is a graph showing what he did from 1 o'clock to 9. He was walking from 1 to the point where starts walking faster and then back down again to 2. The line at 2 is longer than the triangular shape that shows where he speeded up. Then he went back down to 2 and continued at that speed until 9.
Obviously he spent more time at 2 than he did at 4 and therefore his average speed will less than the 4 speed.
Remember that average speed = total distance / total time.
(a) When the spring is compressed 4.5 cm = 0.045 m, it exerts a restoring force on the block of magnitude
<em>F</em> = (1900 N/m) (0.045 m) = 85.5 N
so that at the moment the block is released, this force accelerates the block with magnitude <em>a</em> such that
85.5 N = (1.15 kg) <em>a</em> ==> <em>a</em> = (85.5 N) / (1.15 kg) ≈ 74.3 m/s²
The block reaches its maximum speed at the spring's equilbrium point, and this speed <em>v</em> is such that
<em>v</em> ² = 2 (74.3 m/s²) (0.045 m) ==> <em>v</em> = √(2 (74.3 m/s²) (0.045 m)) ≈ 2.59 m/s
(b) There is no friction between the block and plane, so the block maintains this speed as it slides over the edge. At that point, it's essentially in free fall, so if <em>y</em> is the height of the plane, then
(7 m/s)² - (2.59 m/s)² = 2<em>gy</em> ==> <em>y</em> = ((7 m/s)² - (2.59 m/s)²) / (2<em>g</em>) ≈ 2.16 m
She need to release the cluch slowly and apply force on the accelator other than place her vehicle's gear in Drive and accelerate
<h3>How we drive a car?</h3>
We drive a car by applying pressure on the accelator, remove foot from the brakes and releasing cluch slowly. When the vehicle get speed, we have to change the gear.
So we can conclude that She need to release the cluch slowly and apply force on the accelator for driving a car.

there is 1000 grams in 1 kilogram
Divide
80/1000 = 0.08
0.08 kilograms is your answer
hope this helps
