The time for the collision is 3.6S.
<h3>
What is collision
?</h3>
The collision is an encounter between particles resulting in exchange or transformation of energy.
According to the question,
Force,
F = 5 N
Mass,
m = 3 kg
Velocity,
v₁ = 9 m/s and v₂ = 3 m/s
As we know,
F=m*(v/t)
so,
5=3*(9-3/t)
T=3*6/5
T=18/5
hence, the time for the collision is
T= 3.6S.

Lavoisier organized a list of the known
elements of his day as four categories.
Newlands was the first to organize the
elements and show that properties repeated in a periodic way. Mendeleev and Meyer proposed periodic tables showing a relationship between atomic mass and elemental properties. Moseley organized the elements by atomic number instead of atomic mass.
Answer:
-12
Explanation:
We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21
So substituting gets us 5x - 4(3x) = 21
and we can solve the equation for x
5x - 12x = 21
-7x = 21
x = -3
Now that we have found x, we can find y simply by putting it in the equation y = 3x
y = 3(-3) = -9
Once we have both variables, we can find the answer to x + y
-3 + -9 = -3 - 9 = -12
So the answer to the question
x + y = -12
Answer:
that carbon has 6 protons.
Explanation:
Food that has been prepared or handled should never be placed on the sales floor before it has been properly chilled to ensure the internal temperature is 10° (51°F) or less. It is important to avoid contamination.
It is important to have into account that the higher the temperatures; the faster food will decompose.
Pathogenic microorganisms (such as fungi and bacteria) can reproduce and grow at temperatures as low as 40°F.
The foods may deteriorate even in absence of noticeable modifications in odor, appearance and/or taste.
