Which body part belongs to the circulatory system?

Answers

Answer 1
Answer:


Oh, I just realized you asked for a body part, and there is only one body part in the circulatory system, my bad. That would be the heart. But, it also contains veins, arteries, capillaries, and blood. It's main function to pump blood to supply oxygen to the body.

Hope this helps!
Answer 2
Answer: the would be ((((((heart )))))) the main part  hoped i helped

(2) 5.0 N, up (4) 9.8 N, down

Answers


If the ball weighs 5 newtons, then that's the force of gravity that
attracts it to the center of the Earth.  The force only depends on
the mass of the ball and its distance from the center of the Earth. 
The force of gravity doesn't care whether the ball is moving or at
rest. It doesn't change significantly until the ball moves to some
significant distance off the Earth's surface, which isn't happening
if it's tossed by a human being. 

So we have a downward force of 5 newtons on the ball at all times.
In order to find the net force on it, we have to identify any other
forces besides gravity that are also acting on it.

If the ball were moving through the air, then there would be a force
of air resistance on it, acting opposite to its motion. But when it's
at its maximum height, in the process of turning around from rising
to falling, there's an instant when it's not moving through the air at all,
so gravity is the only force acting on it. At that moment, the net force
on the ball is 5.0 newtons downward.

Which statement best describes an antacid? a)An antacid increases the amount of hydrogen ions b)An antacid neutralizes excess hydrogen ions. c)An antacid decreases the level of hydrogen ions.

Answers

Answer:

The correct answer is option A, An antacid neutralizes excess hydrogen ions.

Explanation:

Antacid neutralizes the acid in the stomach. These are bases/ alkali's. The reaction between an acid and a base in known as neutralization thereby reducing burning sensations produced by the acid.  

The antacid when reaches the stomach form gel like composition that lie on the top of food item in the stomach and prevent the oesophagus from the irritation caused by the acid.  

Answer: option A

Acceleration will only speed up an object?true or false

Answers

False, yes acceleration does speed up an object but, if an object is slowing down it has a negative acceleration, also if an abject is at a constant speed it will have zero acceleration (example: a brick dropped from a plane will stop accelerating whilst still falling when it reaches terminal velocity (a constant speed))

A plane heads due north at an airspeed of 180 km/h. The windis blowing from the west at 60km/h. What is the plane's
velocity with respect to the ground?

Answers

Answer:

190 km/h

Explanation:

randomly picked it

Final answer:

To find the plane's velocity with respect to the ground, we need to consider the combination of the plane's airspeed and the wind's speed and direction. The resulting velocity is 180 km/h north, 60 km/h west.

Explanation:

To find the plane's velocity with respect to the ground, we need to consider the combination of the plane's airspeed and the wind's speed and direction. Since the plane is heading due north and the wind is blowing from the west, we can use vector addition to find the resulting velocity.

First, we break down the airspeed into its north and east components. The north component is 180 km/h, and the east component is 0 km/h because the plane is not moving in that direction.

Next, we break down the wind's velocity into its north and east components. The north component is 0 km/h because the wind is blowing from the west, and the east component is -60 km/h because the wind is against the plane's motion.

Finally, we add the north components together and the east components together. The resulting velocity is 180 km/h north, 60 km/h west. This is the plane's velocity with respect to the ground.

#SPJ3

Elle is playing with a ball in a bus that moves in a straight line with constant velocity. What can you say about the motion of the ball in the moving bus if Elle throws the ball vertically upwards?a the ball will fall back to her

b the ball will land ahead of her

c the ball will land behind her

d the ball will move to the right

Answers

Given that they are all on the same bus that is travelling in a straight line at the same velocity, when Elle throws the ball directly upwards, the ball will simply fall back to her. This is because the bus, Elle, and the ball are all travelling in the same direction and at the same speed. Among the choices, the correct answer is A.

Answer:

the ball will fall back to her

Nuclear fusion occurs in stars.
a. True
b. False

Answers

Answer : The given statement is True.

Explanation -

Nuclear fusion is a thermonuclear reaction in which light stable nuclei combine with each other in order to form a heavy stable nucleus with the release of large amount of energy.

In case of stars, four hydrogen nuclei combine with each other to form a helium nucleus with a release of 26 Mev per cycle.

Thus, nuclear fusion occurs in stars is true statement.


 Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium. The production of new elements via nuclear reactions is called nucleosynthesis. A star's mass determines what other type of nucleosynthesis occurs in its core (or during explosive changes in its life cycle). READ THIS AND YOU WILL UNDERSTAND I THINK IS TRUE
