Answer:
Explanation:
electric field between plates
= surface charge density / ε₀
= 108 x 10⁻¹² / 8.85 x 10⁻¹² (ε₀ = 8.85 x 10⁻¹² )
= 12.20 V/ m
Electric potential diff
= electric field x distance between plates
= 12.20 x 17 x 10⁻³ V
= 0.207 Volt
Hey there friend :)
I would go with Choice A
Sorry if wrong :(
Have a Fabulous day!
Nutrients found in packed items include carbohydrates, fats and proteins and the amount of nutrients present in them is found in calories/grams.
<h3>What are macronutrients?</h3>
Macronutrients are nutrients that contain calories that must be consumed in the diet to perform metabolic functions.
These macronutrients are specified in packed foods, and include proteins, carbohydrates and lipids.
Macronutrients provide 4 calories (proteins and carbohydrates) or 9 calories per gram (fats).
In conclusion, nutrients include carbohydrates, fats (lipids) and proteins and their proportions are expressed in grams.

F I’m not sure if I’m right but I think the answer is F
Answer:
ΔT = 59.9 ° C
Explanation:
For this exercise the brake energy is totally converted into heat
Let's calculate the vehicle energy
K = ½ m v²
Let's reduce the units to the SI system
v = 30 mph (1609.34 m / mile) (1h / 3600s) = 13.41 m / s
Em = K = ½ 1200 13.41²
K = 1.079 105 J
All this energy is transformed into heat
Em = Q
The expression for heat is
Q = m 
ΔT
ΔT = Q / m
The specific heat of iron is = 450 J / Kg ºC
ΔT = 1,079 105 / (4.0 450)
ΔT = 59.9 ° C
