19 feet by 6 feet because 19feet×6feet=114square feet and you need at least 110 and 114 is more than that but none of the other choices go over 110
Charge q is 1 unit of distance away from the source charge S. Charge p is two times further away. The force exerted between S and q is _____ the force exerted between S and p
a. 1/2
b. 2 times
c. 1/4
d. 4 times
Answer:
4 times
Step-by-step explanation:
Given the following :
Distance between q and S (r) = 1 unit
Distance between P and S (r) = 2 × 1 unit = 2
According to coliumbs law:
F = Ke(q1q2) /r^2
Where F = electrostatic force, Ke = coloumbs constant
q1,q2 = charges, r = distance between two charges
For q and S :
Fsq = Ke(q1q2) / 1^2
Fsq = Ke(q1q2) - - - - - equation 1
For P and S :
Fsp = Ke(q1q2) / 2^2
Fsp = Ke(q1q2) / 4 - - - - - equation 2
Dibiding equation 1 by equation 2
Fsq/Fsp = Ke(q1q2) / Ke(q1q2)/4
Fsq / Fsp = Ke(q1q2) × 4 / Ke(q1q2)
Fsq / Fsp = 4 / 1
Using cross multiplication
Therefore, Fsq = 4 × Fsp
Answer:
0>0 or error
Step-by-step explanation:
8m-2(14-m)>7(m-4)+3m
8m-28+2m>7m-28+3m
10m-28>10m-28
0>0
Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides = 
: 
= 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm
Atticus will spend $1.60 on wrapping paper.
Step-by-step explanation:
Given,
Cost of paper per yard = $2.40
Atticus wants to buy = 2/3
Cost of 2/3 yards of paper = 
Cost of 2/3 yards of paper = 
Cost of 2/3 yards of paper = $1.60
Atticus will spend $1.60 on wrapping paper.
