Many organ system serve to help maintain a healthy body. The excretory system is an organ system which is composed of all sweat

glands, the lungs, the rectum, and the kidneys, which all function to remove waste material. How does removing excess waste help the body to maintain overall health?
a removing excess waste helps the body increase its internal temperature.

b removing excess waste prevents people from growing to tall.

c removing excess waste prevents to body from recycling reusable material.

pav-90 [236]

Firstly, we need to make the times and distance equal to compare.

1hr=60mins
Gonz drove 90km in 60mins,so they would drive 45km in 30 mins dividing it by 2.
Because the Rivs had gone 30km in 30mins, Gonz were faster.

For the adverage speed, we should first add the speed of each family in mph , so 90+60, which equals 150 and divide that by 2 because there are 2 speeds so the average speed is 75mph.

P.S English is my second language so tell me if you don't understand something and I will try and explain.

The maximum tension the wire can withstand without breaking is 300 N . A 0.800 kg projectile traveling horizontally hits and emb
topjm [15]

Answer:

Let's investigate the case where the cable breaks.

Conservation of angular momentum can be used to find the speed.

\vec{L}_1 = \vec{L}_2\\\vec{L}_1 = m\vec{v_0} \\\vec{L}_2 = I\vec{\omega}\\

The projectile embeds itself to the ball, so they can be treated as a combined object. <u>The moment of inertia of the combined object is equal to the sum of the moment of inertia of both objects. </u>

I = I_{projectile} + I_{ball}\\I = mr^2 + mr^2\\I = 2mr^2

where r is the length of the cable.

<u>After the collision, the ball and the projectile makes a circular motion because of the cable.</u> So, the force (tension) in circular motion is

F = \frac{mv^2}{r}

The relation between linear velocity and the angular velocity is

v = \omega r

So,

F = \frac{m(\omega r)^2}{r} = m\omega^2 r = 300\\mv_0r  =I\omega\\\\\omega = mv_0r/I\\300 = m(\frac{mv_0r}{I})^2r = m(\frac{mv_0r}{2mr^2})^2r = m(\frac{v_0}{2r})^2r = \frac{mv_0^2r}{4r^2} = \frac{mv_0^2}{4r}\\300 = \frac{0.8v_0^2}{4r}\\1500 = v_0^2/r\\v_0 = \sqrt{1500r}

As can be seen, the maximum velocity for the projectile without breaking the cable is \sqrt{1500r}, where r is the length of the cable.

How do you know you are effectively communicating your thoughts to others?
Bond [772]

5 ways to communicate better

Prepare yourself on the subject. ...

Structure your thoughts. ...

Keep it simple. ...

Listen to others with intent. ...

Engage well.

For an individual to succeed as well as for an organization to succeed, effective communication is crucial. Leaders who can articulate their ideas well are better at motivating and forming bonds with their staff. Furthermore, it's critical to positively and concisely convey your opinions.Whether or not communication is successful determines whether a relationship will succeed. Being able to explain your ideas clearly is only one aspect of effective communication; listening intently is another. It is the capacity to completely comprehend, to demonstrate empathy, and to provide feedback in light of the other person's answer. Simply said, it is the fruitful interchange of ideas and opinions between individuals or organizations.
