Newton's second law states that F=ma so that means force =mass×acceleration force and mass
Answer: $85.80
Explanation: 100kg is equalvilent to 220 lbs, then you multiply 220 by .39 and then you have your answer :)
Speed = distance / time = 21 / 0.25 = 84 Km/hr
Answer:
B because since SHE is in the team she is in group and it is bias because she treats the other teams as competition. Hope this helps!
Explanation:
d = distance between the two point charges = 60 cm = 0.60 m
r = distance of the location of point "a" where the electric field is zero from charge 
between the two charges.
= magnitude of charge on one charge
= magnitude of charge on other charge
= 3
= Electric field by charge at point "a"
= Electric field by charge at point "a"
Electric field by charge at point "a" is given as
= k /r²
Electric field by charge at point "a" is given as
= k /(d-r)²
For the electric field to be zero at point "a"
=
k /(d-r)² = k /r²
/(d-r)² = 3 /r²
1/(0.60 - r)² = 3 /r²
r = 0.38 m
r = 38 cm
