Answer:
grocery stores offering affordable and nutritious foods ( C )
Explanation:
The lack of grocery stores offering affordable and nutritious foods in particular results in food insecurity and sometimes malnutrition because people living in these areas( poor neighborhoods) under research can barely afford three ( 3 ) square meals if Nutritious foods are not sold to them at a subsidized rate in relation to how they are sold elsewhere.
The inability to afford three square healthy meals will result to malnutrition and poor health conditions among people living in these neighborhoods according to the research
Answer:
a) 8*10^-8C/m²
b) +9.04*10^3N/C
c) = -9.04*10^3N/C
Explanation:
Given
Side length, L = 50cm = 0.5m
Charge on the plate, Q = 4*10^-8C
Surface charge density, σ = Q/A
The surface charge density of each part is then half of the total charge density of the plate. Thus,
σ(face) = 1/2σ
σ(face) = Q/2A
σ(face) = Q/2L²
Now we plug in, since we have Q and L
σ(face) = 4*10^-8 / 2*0.5²
σ(face) = 4*10^-8 / 0.5
σ(face) = 8*10^-8C/m²
Magnitude of electric field above the plate is,
E = σ(face) / E•
E = 8*10^-8 / 8.85*10^-12
E = 9.04*10^3 N/C
If we assume this plate lies on the side of the "xy" plane, the electric field is directed in the positive "z" direction. As such,
E = +9.04*10^3N/C
Electric field below the plate has the same magnitude, but different direction. So, E = -9.04*10^3N/C
Answer:
.17Hz
Explanation:
The formula for frequency is f= 1/T , where T is the period.
f = 1/6 and 1/6 ≈ .17
Answer:
Explanation:
As per work energy theorem we know that work done by all the forces must be equal to change in kinetic energy of the car
So here when brakes are applied then work is done by the brakes which is equal to change in kinetic energy of the car
so we know that work done by the brakes is given as
now we will have
