b. 1
c. 0
d. 2

Answers

So we want to know what charge do gamma particles have. Gamma particles are high energy electromagnetic radiation or in other words, gammy rays are high energy photons. Photons have no electrical charge so the charge of gamma rays is equal to zero. The correct answer is c. 0

Answer:

1) An unstable nucleus

c. emits energy when it decays

2)The charge on gamma ray is

c. 0

What environmental factors affect kinetic energy and diffusion?

Answers

There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material. All the mentioned factors directly impact the kinetic energy and diffusion of a material or compound or fluid. Temperature can generally increase the kinetic energy of molecules within a compound or a substance. Increase or decrease of temperature changes the shape and nature of the material concerned. So these natural factors have a big influence on the kinetic energy and diffusion.

Answers
Temparature
Humidity (Amount of molecules in the air)

Explanation
Examples of environmental factors are, temperature, wind, pressure, humidity etc. Kinetic energy is the energy possessed by a body in motion.
This motion can be affected by factors such as rain and humidity since the make the medium more dense. It require more energy to move in a denser medium.
Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. When temperatures are high the molecules get more energy and move more faster increasing the rate of diffusion.

Which terrestrial planet experiences the shortest year?A. Mars
B. Earth
C. Venus
D. Mercury

Answers

D. Mercury
Its year only takes 88 Earth days.

BTW, you could get this exact information if you visit a revolutionary new search engine called Google. Enter in this exact question and Google will return the answer. :)

Also, you probably should know, the closer the planet is to the Sun, the faster it revolves around it, therefore it has a shorter year, and since Mercury is the first planet next to Sun it means that Mercury has the shortest year ☺

A box is being pulled to the right on flat ground with a force of 112 N at an angle of 42° to the horizontal. What is the x-component of the force of tension?

Answers

The x-component is related with the Force through the trigonometric function cosine.

cos(42°) = x-component / F ⇒ x-component = Fcos(42°) = 112N*0.743 = 83.2 N

Dark spots on the photosphere are known asA. the corona.
B. the chromosphere.
C. sunspots.
D. solar wind.

Answers

The dark spots that are found on the photosphere are called sunspots. These are a temporary phenomena and are areas of different temperature compared to the surroundings. Sunspots are at a lower temperature compared to the surrpundings and they are created due to magnetic field flux. They can stay on from a few days to a few months and eventually decay.

Technician A says that a waste spark ignition system fires two spark plugs at the same time. Technician B says that the waste spark ignition system uses ignition coils connected to companion cylinders. Which technician is correct?a. Technician A only
b. Technician B only
c. Both technicians A and B
d. Neither technician A nor B

Answers

Neither technician A nor B. No technician is correct.

What is waste spark Ignition?

Two spark plugs are connected to the ends of one coil in a waste spark ignition system (for a two-cylinder engine) ( for 4 cylinder engine two coils are used, each driving two spark plugs ).

As a result, both spark plugs will light up simultaneously. The first (A) cylinder's compression stroke will ignite one spark plug, while the opposing cylinder's exhaust stroke will fire the second ( wasted ). Cylinder "A" will fire during the exhaust stroke when it is time for cylinder "B" to fire during compression.

Due of the opposing current flow, both spark plugs burn simultaneously from the ends of just one coil. The spark "flows" in this manner from the center to the exterior.

Therefore, Neither technician A nor B. No technician is correct.
