A 100kg sumo wrestler named Bob is doing his daily run. He runs at a velocity of 8m/s. After the run Bob stops for a rest, and sits at the river.
What is Bob's momentum will resting at the river?
Question 10 options:
800 kgm/s
800 kgm/s^s
0 kgm/s
12.5 kgm/s^2

Answers

Answer 1

Answer:

0 kgm/s

Explanation:

The momentum of Bob while resting at the river is 0 kgm/s.

This is because the momentum of any object at rest is 0.

 Momentum is the quantity of motion a body contains. It is mathematically expressed as;

  Momentum  = m x v

m is the mass

v is the velocity

 So at rest, the velocity of a body is 0m/s and therefore, the momentum is O

Calculate the speed for a car that went a distance of 125
kilometers in 2 hours tiine.

Answers

Answer:

62.5 km/hr

Explanation:

Speed can be found by dividing the distance by the time.

s=d/t

We know the car travelled a distance of 125 kilometers in 2 hours. Therefore:

• d=125 km

• t= 2 hr

Substitute the values into the formula.

s= 125 km/ 2 hr

Divide

s= 62.5 km/ hr

The speed of the car is 62.5 kilometers per hour.

if freshwater is added to a region, what happens to seawater density and salinity?

Answers

Answer:

The density and salinity goes down.

Explanation:

Salt water is denser than pure water.  As fresh water is added to salt water the concentration of salt goes down.  Since salinity is the amount of salt in the water that would go down with the concentration.  This would also mean that the density goes down since there is less salt per unit of volume which makes it so that there is less mass per unit of volume.  The formula for density is d=m/v so as the mass goes down per unit of volume so does the density.

6) Define Hydrogen bonds
A. A force created by differences in electronegativity and the small size of the hydrogen atom
make them especially strong.
B. A force created by similarities in electronegativity and the small size of the hydrogen atom
make them especially strong,
C. Forces created by temporary dipoles that result from the movement of electrons in non-
polar molecules.
D. A force created by differences in electronegativity and the large size of the hydrogen atom
make them especially strong,
E. The force between polar molecules when the opposite partial charges of a molecule exert a
force on each other

Answers

Answer:

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

2 The polar structure of water allows it to act as a solvent for many substances. Which of the
following statements best explains why water is considered polar?
F The unequal sharing of electrons results in the water molecule having a slightly negative
charge near its oxygen atoms and a slightly positive charge near its hydrogen atom.
G The equal sharing of electrons by the hydrogen and oxygen atoms form weak bonds that are
easily broken during dissociation.
H The unequal sharing of electrons results in the water molecule having a slightly positive
charge near its oxygen atoms and a slightly negative charge near its hydrogen atom.
The equal sharing of electrons by the hydrogen and oxygen atoms create a molecule that is
neutrally charged

Answers

Answer:

Explanation:

F is the answer, this is because oxygen is slightly delta negative and hydrogen is slightly delta positive. Which creates the permanent dipole that polar molecules have.

Arrange the following elements in order from lowest to highest first ionization energy : AI , Ar, Cs, Na .

Answers

Answer:francium

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Explanation:

The least measure of the energy needed to remove the loosely bound electron of an atom or a molecule is called ionization energy.

The correct order from lowest to highest first ionization energy is:

Cs

Na

Al

Ar

This can be explained as:

(Cs) Caesium will have the lowest energy because in the periodic table it comes in the same group as (Na) sodium.

In the group, from top to bottom the ionization energy decreases.

(Al) aluminium and (Ar) argon lies in the same period.

In a period from left to right the ionization energy increases.

Therefore, Cesium will have the least ionization energy as compared to sodium, aluminium and argon.

Kate wrote the steps of the carbon cycle to describe how carbon is cycled through specific organisms. The steps are in random order.

1 - The rabbit decomposes.
2 - The rabbit eats the carrot plant.
3 - The carrot plant takes in carbon dioxide from the air during photosynthesis.
4 - Carbon compounds are returned to the soil.

Which lists the steps in order?

2, 3, 1, 4
3, 2, 1, 4
3, 4, 2, 1
2, 4, 3, 1

Answers

Answer:

3, 2, 1, 4

Further explanation:

The process of photosynthesis is the process of converting carbon dioxide and water into energy in the form of carbohydrates using sunlight. Usually done by plants that have leafy za called chlorophyll.

Carbohydrates themselves are formed from the C-carbon, H-hydrogen and O-oxygen components

Rabbit food is carrots that contain carbohydrates, which are part of the photosynthesis process

3. The carrot plant takes in carbon dioxide from the air during photosynthesis.

Reaction

6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂

2. The rabbit eats the carrot plant.

Rabbits meet their carbohydrate source for energy by eating carrots

1. The rabbit decomposes.

Rabbits in time will experience a process of decomposition

4 - Carbon compounds are returned to the soil.

The carbon content in rabbits will also be decomposed into the soil again
