False, they don’t use the lures to produce light. Instead they use a strong flash of bioluminescence to scare off predators
The final velocity of the 15 kg mass is 18.33 m/s.
<h3>
Conservation of linear momentum</h3>
The final velocity of the 15 kg mass can be determined by applying the principles of conservation of linear momentum as follows;
Where;
- m₁ is the mass of the first object = 25 kg
- u₁ is the initial velocity of the first object = 15 m/s
- m₂ is the mass of the second object = 15 kg
- u₂ is the initial velocity of the second object = -10 m/s
- v₁ is the final velocity of the first object = -2 m/s
- v₂ is the final velocity of the second object
Thus, the final velocity of the 15 kg mass after the collision is 18.33 m/s.

<span>BAKING A CAKE </span>
Chemical
change is a process where a current substance changes or is made into a new
type of substance. Unlike the physical change, which is reversible. Chemical change stays into a its new form. Take for
instance these -physical change- examples, making ice cubes. The process involves solidification or freezing
where the water becomes ice or solid but when it melts back to its original or typical
form with respect to temperature, it’s still water. When the paper is cut into
pieces it isn’t burned or exposed to a stimuli that can trigger immediate
change in its composition. It’s still the same. On the contrary, baking a cake involves
these different compositions or substances –flour, egg, yeast and etc. that is
baked to a cake, a newly formed unified substance of all the included
ingredients.
