Maria and Miquel were enjoying the fireworks when they got into a chemistry argument. Maria insisted that the fireworks were the

result of a chemical reaction. Miguel disagreed. What would you tell them to solve this argument? A) It is a change of state, solid to gas, due to the addition of energy. B) It was a physical reaction since the fuse was lit and heat was produced. C) The color changes and the release of energy indicate a chemical reaction. D) It is an endothermic reaction because energy was added; therefore it is a chemical reaction, Eliminate

In this case, there is a chemical reaction where there is the burning of fuels that can vary between some within the periodic table, but when the fuel is burned a reaction occurs that gives the coloration the explosions of the fires.

A cat jumps off a table which is 1.5 m high. If the initial velocity of the cat is 10 m/s, at an angle of 37 degrees above the h
Black_prince [1.1K]

Answer:

11.5 m

Explanation:

First, find the time it takes to land.

Given:

Δy = -1.5 m

v₀ = 10 sin 37° m/s

a = -9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

-1.5 m = (10 sin 37° m/s) t + ½ (-9.8 m/s²) t²

-1.5 = 6.02 t − 4.9 t²

4.9 t² − 6.02 t − 1.5 = 0

Solve with quadratic formula:

t = [ -(-6.02) ± √((-6.02)² − 4(4.9)(-1.5)) ] / 2(4.9)

t = 1.44

Now find how far it moves horizontally in that time:

Given:

t = 1.44 s

v₀ = 10 cos 37° m/s

a = 0 m/s²

Find: Δx

Δx = v₀ t + ½ at²

Δx = (10 cos 37° m/s) (1.44 s) + ½ (0 m/s²) (1.44 s)²

Δx = 11.5 m

The cat lands 11.5 meters from the table.

Migration

<h3><u>Explanation; </u></h3>
  • Migration is the movement of animals from one place to another. Migration is an innate behavior that is triggered by changes in the environment.
  • For example, animals may migrate when the days get shorter in the fall. Migration is most common in birds, fish, and insects.
