Answer:
I would say the answer is Non-Biodegradable......eg, plastics, rubber, metals,etc.
HOPE THIS HELPS.
Answer:it’s different materials have different abilities to transfer energy.
Explanation:
Just took it.
<span>Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. </span>
The answer:
we can use newton's second law for finding the value of acceleration
that is F=MxA
M the mass
A is the acceleration
F= P-Fk, Fk= -Mgcosθμ and P=Mgsinθ
μ is the coefficient of friction
The value of μ can be found with the above condition
(<span>pulled up a 28 ° rough ramp at constant speed)
</span>this implies the acceleration is equal to zero
100N - mgsin(28°) -mgcos(28°)μ<span> = 0 , from where </span>
μ= [100N - mgsin(28°)] / mgcos(28°)
μ=0.2
and then,
F=MxA= Mgsinθ -Mgcosθμ finally A=gsin28° -gcos28° x0.2 =2.6m/s²
Answer:
603383.67253 m/s
Explanation:
m = Mass of proton = 
K = Kinetic energy = 1.9 keV
Velocity of proton is given by
The speed of the protons is 603383.67253 m/s
