What are some immediate effects that alcohol have on people?

Answer:

9.66 L

Explanation:

The following data were obtained from the question:

Initial temperature (T1) = 84 ºC

Initial volume (V1) = 10 L

Final temperature (T2) = 72 ºC

Final volume (V2) =..?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T1) = 84 ºC

Initial temperature (T1) = 84 ºC + 273 = 357 K

Final temperature (T2) = 72 ºC

Final temperature (T2) = 72 ºC + 273 = 345 K

Since the pressure is constant, it means the gas is obeying Charles' law. Thus, we shall determine the new volume of the gas as follow:

Initial temperature (T1) = 357 K

Initial volume (V1) = 10 L

Final temperature (T2) = 345 K

Final volume (V2) =..?

V1/T1 = V2/T2

10/357 = V2/345

Cross multiply

357 × V2 = 10 × 345

Divide both side by 357

V2 = (10 × 345) / 357

V2 = 9.66 L

Thus, the new volume of the gas is 9.66 L.

Answer:

traveling at a constant acceleration

Answer:

See the answer below

Explanation:

Acceleration is the ratio of velocity and time. Hence;

Acceleration of the sprinter = 2/1 = 2 m/s2.

When the acceleration is constant and the velocity is double:

acceleration = velocity/time

2 = 4/time,

time = 4/2 = 2 s

Hence, the time it will take for the velocity to double with constant acceleration is 2 s. The sprinter's acceleration during this period would be 2 m/s2.

Acceleration is the change in velocity with time. Hence, the time taken to double velocity is 2 seconds and the constant value of acceleration is 2m/s²

Acceleration is the change in velocity with time ;

Acceleration = (2 ÷ 1) = 2m/s²

Double the value of velocity = 2(2m/s) = 4m/s

At constant acceleration ; Acceleration = 2m/s²

Inputting the Values into the equation :

2 = 4 / time

(2 × time) = 4

Time = 4/2

Time = 2 seconds

Therefore, the time taken to double the velocity is 2 seconds

Answer:

For the car not to strike the deer, the minimum deceleration should be 8 m/s² with a combined instantaneous drivers reaction

Therefore, weather the deer is struck by the car depends on the drivers reaction time and deceleration of the car

Explanation:

The given parameters are;

The distance away from the deer the car was when the driver notices the deer = 25 m

The speed of the car = 20 m/s

Therefore, for the car not to strike the deer, the minimum deceleration of the car should be from 20²/(2 × 25) = 8 m/s² for an instantaneous driver reaction time

For a driver reaction time of 0.5 seconds, we have

Distance moved by car = 0.5 × 20 = 10 meters

Distance of the car from the deer at the start of deceleration = 25 - 10 = 15 meters

Minimum deceleration of the car required = 20²/(2 × 15) = 13.[tex]\bar 3[/tex] m/s²

For the car not to hit the deer, the minimum deceleration should be 8 m/s² with instantaneous driver's reaction.

Car hit the deer will depend on the driver's reaction time and deceleration of the car,

Given here,  

Distance, when driver notice the deer = 25 m  

Speed of the car = 20 m/s

So,  the minimum deceleration

[tex]\bold {= \dfrac {20^2 }{2\times 25} = 8\ m/s^2 }[/tex]

Therefore, for the car not to strike the deer, the minimum deceleration of the car should be 8 m/s² with an instantaneous driver reaction time.

Forensic anthropology is a branch of anthropology that analyzes the remains of a body in order to solve criminal cases. A forensic anthropologist, therefore, is a scientist that studies and analyzes remains of bodies in order to unravel criminal cases.

Archaeology, on the other hand, has to do with the analyses of artifacts in relation to human culture. An archaeologist is a person that studies artifacts mainly.

Hence, while a forensic anthropologist specializes in the study of bodies, archaeologist searches and studies artifacts.

Answer:

95000cm

Explanation:

Given parameter:

       0.95km

Problem;

  Convert km to cm;

Solution:

      100cm = 1m

      1000m = 1km

  So,

        100,000cm = 1km

             1km  = 100,000cm

             0.95km  = 0.95 x 100000 = 95000cm

The projectiles launch allows to find the answer for the initial velocity of the stone is:

            v = 17.71 m / s

Projectile launching is an application of kinematics for motion in two dimensions, where there is no acceleration on the x axis and the acceleration on the y axis is the gravity acceleration.

In the attached diagram we can see a corner of the movement. Where the x axis is horizontal and the y axis is vertical, where the zero of the system is at the base of the cliff

In this case the stone is thrown horizontally, therefore its initial vertical speed is zero, let's find the time it takes to reach the base of the cliff

           y = y₀ + [tex]v_{oy}[/tex] t - ½ g t²

where y and y₀ are the current and initial position, [tex]v_{oy}[/tex] is the initial vertical velocity, g the acceleration of gravity and t the time

When reaching the bottom its height is zero (y = 0) and the highest part its initial height is y₀ = 25.00 m

           0 =y₀ + 0 - ½ g t²

          t = [tex]\sqrt{\frac{2y_o}{g} }[/tex]

Let'se calculate

           [tex]t = \sqrt{ \frac{2 \ 2.25 }{9.8 } }[/tex]

           t = 2,259 s

They indicate that the stone fell at a horizontal distance of 40 m,

           x = [tex]v_{ox}[/tex] t

            v_{ox} = [tex]\frac{x}{t}[/tex]

           v_{ox}  = [tex]\frac{40}{2.259}[/tex]

           v_{ox} = 17.71 m / s

In conclusion, using theprojectiles launch we can find the answer for the initial velocity of the stone is:

            v = 17.71 m / s

Molecule

Explanation:

A molecule is the smallest particle of sugar (glucose - C6H12O6) or any other substance because a molecule possess all properties of that particular substance.

Molecules are responsible for all the chemical and physical properties of a substance, so molecules decided the properties of sugar as well. If the molecule will be broken, it will lose its properties. Sugar is composed of molecules that include 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen.

Hence, the correct answer is "Molecule".

Answer:

t = 150 [s]

Explanation:

To solve this problem we must take into account that the car travels at a constant speed, that is, there is no acceleration or it is equal to zero, therefore we can use the following equation of kinematics.

X = Xo + (v*t)

where:

x = final point [m]

Xo = initial point [m]

v = constant velocity = 20 [m/s]

t = time [s]

X - Xo = the distance traveled = 3000 [m]

3000 = 20*t

t = 150 [s]

This Means Nothing to ME

Explanation:

I HAVE A tradition of doing a little analysis on one of my favorite movie franchises to celebrate Star Wars Day (May the Fourth Be With You). Given that Rogue One: A Star Wars Story recently appeared on DVD and various streaming services, I think its OK to look at that film without worrying about spoilers. In this case, I will calculate Darth Vader's power output as he uses the Force.

To calculate the power needed to lift this poor fellow, I can estimate how high Vader lifts him and at what speed. If I guess that the rebel is 1.75 meters tall (the average height of a man here on Earth, so I'll assume the same holds true on whatever planet the rebel calls home) then I can get an approximate scale for the scene. With that, I can use video analysis to plot the vertical position of the rebel as a function of time

Answer:

The first reason for children to have pretend play is that it allows the child to learn how to interact socially. The child is able to take turns, share responsibility, develop how people feel and react the situation. Another reason is that it helps the child develop their critical thinking skills. They may have to creatively solve a problem, or think what they may need in real life for the pretend play. It increases the child's ability to think through those types of situations. The final reason it is important for a child to have pretend play is that it helps develop their language skills. If the child is imitating a dad, mom, teacher, etc. they will attempt to use the same language that person uses. This helps the child connect new language abilities and skills.
