Answer:

blank space can determine any quantity

Explanation:

a blank works so that people can determine amounts or rules that best suit their preferences or situations, as is the example of an amount of money that is lent in a bank, banks already have made loan contracts, With the space of the white quantity, this for reasons of saving time and having an already legalized agreement that can be applied to any of its customers, then in that space they put the desired amount, the same happens with a certain type of sales, it is also used to set rules

A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.50 × 10 4 1.50×104 rad/s to an angular s

KATRIN_1 [288]

Answer:

0.32 s

Explanation:

Initial angular speed: $\omega_i = 1.50 \cdot 10^4 rad/s$

Final angular speed: $\omega_f = 3.35\cdot 10^4 rad/s$

Angular rotation: $\theta=2.02\cdot 10^4 rad$

The angular acceleration of the drill can be found by using the equation:

$\omega_f^2 - \omega_i^2 = 2 \alpha \theta$

Re-arranging it, we find $\alpha$ , the angular acceleration:

$\alpha = \frac{\omega_f^2 - \omega_i^2}{2\theta}=\frac{(3.35\cdot 10^4 rad/s)^2-(1.50\cdot 10^4 rad/s)^2}{2(2.02\cdot 10^4 rad)}=22,209 rad/s^2$

Now we want to know the time t the drill takes to accelerate from

$\omega_i =0$

$\omega_f = 6.90\cdot 10^4 rad/s$

This can be found by using the equation

$\omega_f = \omega_i + \alpha t$

where $\alpha$ is the angular acceleration we found previously. Solving for t,

$t=\frac{\omega_f - \omega_i}{\alpha}=\frac{22,209 rad/s^2}{6.90\cdot 10^4 rad/s}=0.32 s$

How does genetic variation prevent environmental factors from wiping out a population?

ludmilkaskok [199]

With more genetic variations, the more adaptations will be developed that will help the population survive the changing environment.
For example, if an environment starts to grow lighter fields, a population will start to develop genetic variation that will help camouflage the animal. Like, make the animal start to have lighter skin to camouflage.

Rosa was looking for patterns to help predict the products of chemical reactions. She recorded three similar decomposition react

kipiarov [429]

The products should she record in the last row of the table : <u>2LiCl + 3O₂</u>

<h3>Further explanation</h3>

There are several chemical reactions, namely:

Formation reaction
Decomposition reaction.
Replacement reaction.
Multiple replacement reactions
Neutralization reaction.
Combustion reaction.
Polymerization

The decomposition reaction in a chemical reaction shows the decomposition reaction of a compound into its constituent elements or compounds

Rosa recorded three similar decomposition reactions

Reactions that occur :

1. 2 NaClO₃ ⇒ 2NaCl + 3O₂

2. 2KClO₃ ⇒ 2KCl + 3O₂

3. 2LiClO₃ ⇒ 2LiCl + 3O₂

There are similarities in the decomposition that forms oxygen and chloride compounds

In a stormy sea, 2 waves pass a fixed point every second, and the waves are 10 meters apart. What is the speed of the wave?

Kitty [74]

   Speed of a wave = (frequency) x (wavelength)

   = (2 per second) x (10 m)

   = 20 m/s .
