Answer:
7000 kg*m/s E
Explanation:
Momentum formula: p=mv
m=200kg
v=35 m/s East
p=(200kg)(35m/s E)
m=7000 kg*m/s E
If you want to simplify it further, m=7*10^3 kg*m/s E
Answer:
[tex]\boxed {\boxed {\sf 7000 \ kg*m/s \ E}}[/tex]
Explanation:
Momentum is the product of mass and velocity.
[tex]p=m*v[/tex]
The mass is 200 kilograms and the velocity is 35 meters per second east.
[tex]m= 200 \ kg \\v= 35 \ m/s \ E[/tex]
Substitute the values into the formula.
[tex]p= 200 \ kg * 35 \ m/s \ E[/tex]
Multiply.
[tex]p= 7000 \ kg * m/s \ E[/tex]
The rhino has 7000 kg*m/s E of momentum.

Ce presiune au 40L gaz la temperatura de 100⁰C, dacă la presiunea de 6 atm și temperatura de 50⁰C volumul ocupat este de 20L.
Answer:
3,46 atm
Explanation:
Tenemos;
P1 =?
T1 = 100 + 273 = 373 K
V1 = 40 litros
P2 = 6 atmósferas
T2 = 50 + 273 = 323 K
V2 = 20 litros
Desde;
P1V1 / T1 = P2V2 / T2
P1V1T2 = P2V2T1
P1 = P2V2T1 / V1T2
P1 = 6 * 20 * 373/40 * 323
P1 = 44760/12920
P1 = 3,46 atm
Which best describes the relationship between the circulatory system and the respiratory system?
The circulatory system is the transport system for the respiratory system.
The respiratory system is the transport system for the circulatory system.
The circulatory system diffuses red blood cells into the respiratory system to pick up oxygen.
The respiratory system transfers hemoglobin to the red blood cells of the circulatory system.
Answer:

Explanation:
yw
The respiratory and circulatory systems work together to maintain the homeostasis of the human body. The circulatory system is the transport system for the respiratory system. The correct option is A.
What is respiratory system?The network of organs and tissues which help us to breathe is defined as the human respiratory system. The main function of this system is to introduce oxygen into the body and to expel carbon dioxide from the body.
The human circulatory system consisting of arteries, veins and capillaries provide all the essential nutrients, minerals and hormones to the various parts of the body.
The respiratory system does not work alone in transporting oxygen through the body. The oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen rich blood to tissues and cells.
Thus the correct option is A.

On a coordinate plane, which single transformation could map point A (3,-4) onto point A' (1.5,-2)? *
Answer: A dilation with rule: [tex](x,y)\to(\dfrac12x,\dfrac12y)[/tex]
Explanation:
A dilation is a non-rigid transformation that creates an image that is the same shape as the original but has a different size.
It uses a scale factor k such that
[tex](x,y)\to(kx,ky)[/tex]
(x,y)= coordinates of original figure
(kx,ky) = corresponding coordinate in the image.
To transform: A (3,-4) onto point A' (1.5,-2).
Using scale factor k= [tex]\dfrac12[/tex], we have
[tex]A(3,-4)\to A'(\dfrac12\times3, \dfrac12\times-4)=A'(1.5,-2)[/tex]
Required rule: [tex](x,y)\to(\dfrac12x,\dfrac12y)[/tex]

Answer:
A sample of helium gas has a volume of 620mL at a temperature of 500 K. If we ... to 100 K while keeping the pressure constant, what will the new volume be?
Explanation:
A sample of helium gas has a volume of 620. Ml at a temp of 500 K. If we decrease the temperature to 100K while keeping the pressure constant 124 ml will the new volume be.
What is volume ?Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected.
The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
According to Charles' Law, at constant pressure,
V1 / T1 = V2 / T2
V1 = 620 ml and T1 = 500K, V2 = ? , T2 = 100K
620 ml / 500K = V2 / 100K
V2 = ( 620 ml ) ( 100K ) / 500K
Volume = 124 ml
Thus, If we decrease the temperature to 100K while keeping the pressure constant 124 ml will the new volume be.

Why does a feather fall slower than a rubber ball? How could you make them hit
the ground at the same time?
Answer:
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and a rubber ball dropped together. Air resistance causes the feather to fall more slowly, while the ball falls more fast.
In this lab, you will use a precise scale and heat to identify the mole ratio of an unidentified hydrate. Write an investigative question that you can answer by doing this experiment.
Answer:
How can drying a hydrate help you determine its mole ratio of water to salt?
Explanation:
When we are investigating the mole ratio of a hydrate by heating we can have some scientific questions to solve here, like how much heat energy is needed to dry the hydrate of specified quantity, similarly how the evaporation helps to determine the mole ratio?
What are hydrates?Some compounds easily absorbs water molecules into them and forms hydrates that are compounds associated with water molecules. The property getting moisture easily is called deliquescence.
There are many compounds which able to form hexahydrates, penta hydrates, dihydrates etc. The mole ratio with water depends on the nature of the compound and mostly to the bond type.
By heating the hydrates can be dried by evaporation of water. But the temperature used to evaporate varies with the water content. Thus, question we can have here, is how heating helps to find mole ratio and how heat energy is used to make it dry.
