Answer:
102 km/h
Explanation:
x = distance of car A at any time from the intersection
x₀ = distance of car A at some time = 0.4 km
= Speed of car A = 75 km/h
y = distance of car B at any time from the intersection
y₀ = distance of car B at some time = 0.3 km
= Speed of car B = 70 km/h
d = distance between the two cars at any time
d₀ = distance between the two cars at some time
v = rate of change of distance between the cars
Using Pythagorean theorem
d²₀ = x₀² + y₀²
d²₀ = 0.4² + 0.3²
d₀ = 0.5 m
Distance between the two cars at any time is given using Pythagorean theorem as
d² = x² + y²
Taking derivative both side relative to "t"
(0.5) v = (0.4) + (0.3)
(0.5) v = (0.4) (75) + (0.3) (70)
v = 102 km/h
Answer:
Diffusion of water, salts, and waste products occurs in the kidneys. Diffusion of calcium from food into cells occurs in the intestines. Molecules are not the only things that can diffuse. Heat from the body diffuses away in the form of sweat that evaporates.
