Answer:

I have also wondered this.

Explanation:

Biology, genetics, and overall life science are missing the answer to this:

"What makes the particles in our DNA group together and carry out functions? How did the first life come about? Why can't our bodies just keep growing as we age and not die? How did life get on Earth? How exactly do different compounds make life? Is there really a purpose of life? Is there really a specific set of guidelines to specify what is nonliving and what is alive.

This is where religion comes in, and there should be no discrimination towards other religions. It is just someone else's beliefs. You can believe anything you want. Just do not act unintelligently or be against any religion etc.

If you are talking about wanting to die( Brainly says I can't use the word), don't do it. You can find help somewhere if you actually want to look for it. Depression can get you down but don't do drugs, it will only make it worse.

No purpose of life has been scientifically proven, but that does not mean you have to die. Wait to die of old age to see if there is an afterlife. Enjoy life while you have it. Some old people are probably thinking "I wish I did more in my life and learned to enjoy every bit of it" before they die and see if there is an afterlife. And if you learn there is an afterlife, don't be like "I told you so" because you should respect other people's beliefs, and anyways you can't tell a living person that because you are dead. Unless you are a ghost, but that is another disputed matter.

vazorg [7]

Answer:

Option B

Explanation:

<h3>According to Newton's third law, for every reaction there will be equal and opposite reaction</h3>

Here in this case the force of the club hitting the golf ball will be in one direction and the force acting on club due to golf ball will be in opposite direction and magnitude of this force will be same as the magnitude of the force of the club hitting the golf ball

In this case the action will be the force of the club hitting the golf ball and reaction will be the force acting on club due to golf ball

∴ The club pushes against to golf ball with a force equal and opposite to the force of the golf ball on the club

On a vacation flight, you look out the window of the jet and wonder about the forces exerted on the window. Suppose the air outs

user100 [1]

Answer:

A) $\Delta P = 14512.5 Pa = 14.512 kPa$

B) F = 1632.65 N

Explanation:

Given details

outside air speed is given as $v_2 = 150 m/s$

since inside air is atmospheric , $v_1 = 0 m/s$

a) By using bernoulli equation between outside and inside of flight

$P_1 + \frac{1}{2} \rho v_1^2 + \rho gh = P_2 + \frac{1}{2} \rho v_2^2 + \rho gh$

$\Delta P = \frac{1}{2} \rho v_2^2 - \frac{1}{2} \rho v_1^2$

$\Delta P = \frac{1}{2} \rho[ v_2^2 -v_1^2]$

$\Delta P = \frac{1}{2} 1.29 [ 150^2 - 0^2]$

$\Delta P = 14512.5 Pa = 14.512 kPa$

b) force exerted on window

Area of window $= 25\times 45 = 1125 cm^2 = 0.1125 m^2$

We know that force is given as

$F = P\times A$

$F = 14512.5 \times 0.1125$

F = 1632.65 N

2. A student drives 7.8-km trip to school and averages a speed of

Alekssandra [29.7K]

Answer:

<em>The total time is: t=451.22 sec</em>

<em>The average speed is: V=34.57 m/s</em>

Explanation:

<u>Average speed</u>

The average speed is calculated by dividing the total distance traveled by an object (x) by the total time it took it to travel that distance (t).

$\displaystyle V=\frac{x}{t}$

Since the student makes the trip in two parts, we have to calculate the total distance and the total time.

We know the distance to school is 7.8 Km = 7,800 m. The student makes his way home over the same distance, thus the total distance is

x=2*7,800 m=15,600 m

The first trip to school was done at an average speed of v1=32.6 m/s. Knowing the distance and speed, we can calculate the time:

$\displaystyle t1=\frac{x1}{v1}=\frac{7,800}{32.6}=239.26\ sec$

The second trip back home was done at an average speed of v2=36.8 m/s. Let's calculate the second time:

$\displaystyle t2=\frac{x2}{v2}=\frac{7,800}{36.8}=211.96\ sec$

The total time is:

$t=239.26\ sec+211.96\ sec=451.22\ sec$

$\boxed{t=451.22\ sec}$

The average speed is:

$\displaystyle V=\frac{15,600}{451.22}=34.57\ m/s$

$\boxed{\displaystyle V=34.57\ m/s}$

For a chair to be balanced on one leg, where must the center of gravity be located? A. in the center of the seat B. toward the f

mixer [17]

Answer:

The correct answer is c

Explanation:

When a body is in rotational equilibrium, the relationship must be met

∑ τ = 0

Σ F d = 0

therefore the forces that are exerted on the body that are represented in the center of gravity are different from zero, therefore, to maintain balance the distance must be zero, therefore the center of gravity must be above the leg where the body is balancing

The correct answer is c
