Answer:
Explanation:
From the question, mass(m)=2200kg, unitial velocity(u)=18m/s and final velocity(v)=0m/s
We can calculate the work done to bring the car to a stop from the relation;
,where
W=Work done
F=Force
S=distance
Also,
Putting eqn(2) into equn(3) we obatin
From the equation of motion;
and
Substituting these into eqn(3), we obtain;
Substituting the values of m,u and v into the equation, we obtain.
Simplifying, we obtain;
NB: The negative sign indicates that the car decelerated to a stop.
Hence the Work done on the car is
Answer:
The freezing point at which water — a liquid — turns to ice — a solid — is 32°F (0°C). ... It is referred to as the freezing point when temperatures decrease below 32°F (0°C), causing water to change state from a liquid to a solid (ice), as happened with the cup of crushed ice immersed in the very cold salt/ice mixture.
Answer:
It is true.
Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of ions. The results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.
A mass spectrum is a plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds.

Answer:
C) 128 kg*m/s
Explanation:
When you double something you multiply it by 2 most of the time. 64*2=128 or you can add it 64+64=128. Hope this helps.
