Answer:
The two objects will collide with the same position vector for all three components at exactly t = 4 s
Explanation:
For two particles starting out at the same time to collide, their position Vector's at the time of collision must be exactly the same.
So, at the collision point, position vector of object 1 is equated to that of object 2.
r₁ = (t², 13t-36, t²)
r₂ = (7t-12, t², 5t-4)
At he point of collision
t² = 7t - 12
t² - 7t + 12 = 0
t² - 4t - 3t + 12 = 0
t(t - 4) - 3(t - 4) = 0
t = 3s or t = 4s
13t - 36 = t²
t² - 13t + 36 = 0
t² - 4t - 9t + 36 = 0
t(t - 4) - 9(t - 4) = 0
t = 9s or 4s
t² = 5t - 4
t² - 5t + 4 = 0
t² - 4t - t + 4 = 0
t(t - 4) - 1(t - 4) = 0
t = 1s or t = 4s
The three components intersect at other times, but at t = 4s, they all intersect at the same time! Meaning that, at this point the two objects are at the same place with the same position vector at that time.
Voltage = (current) x (resistance)
Voltage = (1.5 A) x (2 ohms)
In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE <em>3 volts</em> from the battery.
An increase in the concentration of sugar in a solution leads to the increase in boiling point of the solution.
<h3>What is boiling point?</h3>
Boiling point of a solution is that pressure exerted on a liquid by its surrounding is equal to the vapour pressure of the liquid.
When there is an increase in concentration of solute, more space will be occupied in the fluid leading to an increase in the boiling point of the fluid.
Therefore, An increase in the concentration of sugar in a solution leads to the increase in boiling point of the solution.

I’m not completely sure but if I had to guess I would say lithium oxide
