Answer:
13800 N
Explanation:
Impulse is the product of average force and time expressed as I=Ft where I is the impulse which results into change in momentum, F is the average force and t is the time of impact. Making F the subject of formula then
Substituting I with 13.8 N.s and time, t witg 0.001 s then the average force is calculated as
Therefore, the average force is equivalent to 13800 N
Potential energy is when the roller coaster rises. Kinetic energy is when the roller coaster declines.
I think the correct answer from the choices listed above is the second option. In Niels Bohr’s model of the atom, electrons move like planets orbiting the sun. His model of atom is seen as<span> very small, positively charged nucleus which contains proton and neutron surrounded by negatively charged electrons.</span><span> These electrons travel in circular orbits around the nucleolus. </span>
Answer:
50N
Explanation:
this is because 5×10all over 100 ,0 will cancile 0 remaining 10 ,1 into 10 ,10times ,so 5×10 =50N
The heart will beat 60 times in 1 minute.
