Answer:
0.304 m/s2
Explanation:
If the first child is pushing with a force of 69N to the right and the 2nd child is pushing with a force of 91N to the left. Then the net pushing force is 91 - 69 = 22 N to the left. Subtracted by 15N friction force then the system of interest is subjected to F = 7 N net force tot he left.
We can use Newton's 2nd law to calculate the net acceleration of the system
Force is a vector quantity
so pulling from opposite side will be negative
so
750+(-500)= 250N
C is the right answer
becauseause the man on the right applies greater force.
Answer:
The answer to your question is 6 km/s
Explanation:
Acceleration is a change in velocity with respect to time, its units are m/s² or km/h².
Data
vo = 15 km/h
vf = 45 km/h
t = 5 s
Formula
Substitution
a = (45 - 15) / 5
a = 30 / 5
a = 6 km/s
I believe the correct answer would be "A" energy source.
Deuterium is also known as heavy hydrogen and takes the symbol 2H. What makes this heavy is due to the additional neutron present in it. Therefore, everything that is being mentioned above as the description of deuterium is applicable. Therefore, the answer would be option E: All of the above. Hope this helps.
