A man pushes a stalled car with a force of 100 N. If the acceleration of the car is 0.75 m/s 2 , what is the mass of the car?

shutvik [7]

125 because f=ma so you would use 100=mx0.75

Below, the two-way table is given for a class of students. Freshmen Sophomore Juniors Seniors Total Male 4 6 2 2 Female 3 4 6 3

julsineya [31]

The required probability is 3/4.We have to compute the probability

P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.

Determine the total number of juniors.Juniors=2+6=8

<h3>What is the probability?</h3>

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

Since the number of females who are junior is 6, determine the required probability.

P(Female|Junior)=6/8=3/4

Therefore, the required probability is 3/4.

LINK THE WORDS TO THE UNDERLINE. The 4 most common _____________ are solids, liquids, gases and plasmas. The _______________ are

Savatey [412]

The 4 most common States of matter are solids, liquids, gases and plasmas. The States of matter are also called the phases of matter.

2. For a given pure substance, the amount of thermal energy is what separates the different states of matter. The solid state has the least thermal energy. The liquid state has more thermal energy than the solid state. The gaseous state has more thermal energy than the liquid state. And the plasma state has the highest thermal energy of the 4 states of matter.

3. Changing from one state of matter to another is called a phase change. Solids can phase change to liquids or gasses. Liquids can phase change to solids or gasses. Gasses can phase change to liquids or solids.

4. Frost forms from water vapor depositing as ice crystal without first becoming liquid water. This is called Deposition. Deposition is also used in industry to put a thin layer of aluminum on mylar for helium balloons and for potato chip bags.

5. Put wet laundry outside on a clothes line in freezing weather and it will dry. The process is called Sublimation and a solid phase changes to a gas without first melting into a liquid. Dry ice (frozen CO2) undergoes Sublimation and becomes CO2 gas. It skips the liquid state and because we see something that looks like normal ice disappear without making a puddle, we call it dry ice.

6. Vaporization is when a liquid becomes a gas. It can happen slowly at cool temperatures and this is called evaporation. Or it can happen faster at the boiling temperature of the liquid and this is called boiling.

7. In the summer time, I love a glass filled with ice water. But water vapor in the air undergoes Condensation and becomes liquid water on the outside of the glass. Fog and clouds are also formed by Condensation of atmospheric water (water vapor) condensing into liquid water drops.

8. Thermic refers to thermal energy, usually perceived as heat or temperature. Endo refers to “inside.” Endothermic means heat is moving INTO a process and is stored in the products of that process. Heating up liquid water is Endothermic because heat is being put into the process of raising the water temperature and is stored in the kinetic motion of the water molecules. Melting ice into liquid water is Endothermic because heat is being used to break most of the attractive bonds between water molecules so that the molecules are still close to each other, but can slide around each other.

9. Thermic refers to thermal energy, usually perceived as heat or temperature. Exo refers to “outside” like exiting a room to the outside. Exothermic means heat moving out of a process. The heat energy comes from energy stored as kinetic motion of the molecules and broken bonds of attraction. When liquid water cools down, heat comes out of the water and goes to the environment around the water. This is Exothermic. Liquid water undergoing the phase change to become solid water (ice) is Exothermic. The thermal energy absorbed to “melt” the ice is released as the ice freezes.

10. The Kinetic Theory of Matter theorizes that all matter is made of tiny particles (atoms and molecules) that are in constant motion. The amount of motion is an indication of the temperature. At absolute zero, all kinetic motion stops.

In which wavelength region(s) would we need to carry out observations in order to study the accretion disk around a white dwarf

Inga [223]

In “Ultraviolet light” and “X-ray” light wavelength regions are needed to carry out observations to study the “accretion disk” around “a white dwarf” in a “binary system”.

Explanation:

Occurrence of an accretion disk is due to presence of diffuse material around a white dwarf in orbital motion. White dwarf is constituted from electron-degenerate matter therefore also called as degenerate dwarf in binary system. Frictional forces and gravitational forces are responsible to compress and high “temperature” of the material, results with emission of “electromagnetic radiation”. “Accretion disks” of white dwarf radiate in the UV-rays and X-rays wavelength region of spectrum.
