Match each description to a type of radiation Drag each item to the appropriate bin.
Answers
Answer:
Explanation:
Beta radiations:
mass 1/200 , charge -1, medium penetration
Beta radiations are result from the beta decay in which electron is ejected.
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminum is used to block the beta radiation
Properties of alpha radiation:
mass 4 amu, charge +2, least penetration
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
Gamma radiations:
mass 0, charge 0, deepest penetration
Gamma radiations are high energy radiations having no mass.
These radiations are travel at the speed of light.
Gamma radiations can penetrate into the many materials.
These radiations are also used to treat the cancer.
Lead is used for the protection against gamma radiations because of its high molecular density.
The lead apron are used by the person when treated with gamma radiations.

Answers
Answer:
D. Force
Explanation:
Applied force can cause change in direction
A force applied at an angle to the direction of motion of an object can cause it to change direction. It is possible that the object keeps going at the same speed, if the force is applied perpendicular to the direction of motion. But the velocity of the the object changes.

Which is the best way to determine if an object is made of pure silver?
O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.
Answers
Answer:
The correct option is;
Determine the density of the object and compare the known density of pure Silver
Explanation:
The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)
The density is then fond by dividing the weighed mass by the volume the object displaces when immersed
Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.
In 1973, the insecticide called DDT wasbanned in the United States due to concerns that itwas toxic to fish and that it may have affected birds.There is little scientific evidence that DDT is directlyharmful to humans. How could banning DDT be beneficial to human health
Answers
Answer:
See explanation
Explanation:
DDT is dichlorodipphenylrtrichloroethane. It is was a popular insecticide used for agricultural purposes. Racheal Carson's book, silent springs drew attention to the use of insecticides such as DDT in agriculture.
DDT is a non-biodegradable, fat-soluble compound. It enters into the food chain and has the ability to bioaccumulate in the human body where it becomes deposited in the adipose tissue.
There is no direct harmful effect of DDT to humans, however, when oxidation of DDT takes place in body many harmful metabolites are released into the body causing harmful effects to human health such as; breast cancer, male infertility, miscarriages and low birth weight, developmental delay and liver damage.
There is convincing empirical evidence supporting the carcinogenicity of DDT its main metabolites DDE and DDD, however, many studies on the harm caused by DDT and its main metabolites in the body have so far led to inconclusive, and sometimes negative, results

1) The constant terms for the experiment should be defined, which in this case are
a) The volume of the water which is 60 ml in both subjects of the experiment
2) The definition of the variable that produces the effect that is being monitored, which is the use of the different temperatures in the two experimental subjects
3)The environmental limits of the experiment, which is the water and the food coloring used

Physical and Chemical Properties of Magnesium
Here is an EXAMPLE of how it has to be like. Instead of Mercury, you HAVE to do Magnesium
Physical Properties of Mercury: ”I’m a highly stable element, so you can count on me”
Chemical Properties of Mercury: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon”
Answers
Answer:
Some of the physical and chemical properties of magnesium are:
-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.
-Magnesium is closely related to manganese and magnetite.
-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.
-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element

Calculating Density Warm Up
Answers
Answer:
2
Explanation:
33-25=8
48/8=6
The density (g/cm3) of 48.0 g of a metal if the level of water in a graduated cylinder rises from 25.0 mL to 33.0 mL after the metal is added density will be 6.0 g/cm3. option B is correct.
What is density?
The density of any substance is the division of the mass of the given substance to the volume of the given substance and its unit is centimeter cube.
where,
density = mass of substance / volume of the substance
mass of substance = 48.0 g
volume of substance = 33.0 - 25.0 = 8 ml
substituting the value in the formula,
density = 48.0 / 8 = 6 cm³
Therefore, density (g/cm3) of 48.0 g of a metal if the level of water in a graduated cylinder rises from 25.0 mL to 33.0 mL after the metal is added density will be 6.0 g/cm3. option B is correct.

Does changing the number of protons change the identity of the element you have built ?
Answers
Answer: Yes.
Explanation:
the number of protons in the nucleus determines an element's identity. Chemical changes do not affect the nucleus, so chemical changes cannot change one type of atom into another. The number of protons in a nucleus does change sometimes, however. The identity of the atom, therefore, changes.
