Answer:
![a=-3.37\ m/s^2](https://tex.z-dn.net/?f=a%3D-3.37%5C%20m%2Fs%5E2)
Explanation:
Given that,
A car accelerates negatively from 35m/s to 8m/s in 8s.
We need to find the car's acceleration.
Initial speed, u = 35 m/s
Final speed, v = 8 m/s
Time, t = 8 s
The acceleration of an object is equal to the rate of change of velocity. So,
![a=\dfrac{v-u}{t}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv-u%7D%7Bt%7D)
Put all the values,
![a=\dfrac{8-35}{8}\\\\a=-3.37\ m/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B8-35%7D%7B8%7D%5C%5C%5C%5Ca%3D-3.37%5C%20m%2Fs%5E2)
So, the acceleration of the car is equal to
.
Answer:
B
Explanation:
If the student needs one gram but so far only has 0.37 grams, then the amount they need is the difference between what they need and how much they already have. 1-0.37=0.63 grams.
...which isn't actually an option because none of them have decimal points but I would say it is B anyway because it is the equivalent ratio and maybe there was a typo.
Hope this helped!
Answer:
In organic chemistry, the structural formula shows the bonding and general layout of the molecule.
Explanation:
It can also help in naming the molecule, as many compounds with the same molecular formula have different structural formulas, for example cycloalkanes and alkenes, or aldehydes and ketones.
It tells us about the constituents of the compound, or in other words, the functional groups present. This enables us to predict what kind of properties the compound has and what kind of reactions it can undergo.
It can also help us determine the stereochemistry (shape and spatial orientation) of the compound. This is especially important in organic chemistry and organic chemstry, since certain important reactions will proceed if and only if a molecule with the right shape is employed.
Answer:
120mph
Explanation:
Google
divide the speed value by 1.467
or
176 times 60 second in a minute times 60 minutes in an hour
than divide by 5280 the amount of feet in a mile
