Law of conservation of mass
Answer:
d = 142.5 m
Explanation:
This is a vector exercise. Let's calculate how much the boat travels in the 40s
d₀ = t
d₀ = 0.75 40
d₀ = 30 m
Let's write the kinematic equations
Boat
x = d₀ + t
x = 0 + t
At the meeting point the coordinate is the same for both
d₀ + t = t
t ( - ) = d₀
t = d₀ / ( - )
The two go in the same direction therefore the speeds have the same sign
t = 30 / (0.95-0.775)
t = 150 s
The distance traveled by man is
d = t
d = 0.95 150
d = 142.5 m
The most crucial information would be its atomic number.
Answer:
Un elemento es un material compuesto de un simple tipo de átomo, un compuesto es una sustancia formada por dos o más elementos que se combinan químicamente y una mezcla es la combinación de sustancias, iguales o no, que pueden ser separadas por métodos físicos.
