Which characteristics do all terrestrial planets have? Select all that apply.A. Water
B. Iron core
C. Rocky crust
D. Thin atmosphere
E. Dense atmosphere
F. Relatively high density

Answers

Answer 1
Answer: "Terrestrial" means 'on Earth' or 'like Earth'.

The so-called 'terrestrial planets' are Mercury, Venus, Earth, and Mars.
The asteroid belt separates them from the 4 gas-giant planets, in a wide
gap where there should be another planet but there isn't.

Among the terrestrial planets as a group:

A).  Water
       No.  Only earth has water (now).

B).  Iron core
       Yes.  Most probably all.

C).  Rocky crust
       Yes.  All.

D).  Thin atmosphere.
E).  Dense Atmosphere.
       No. 
       Only Venus has a dense one.
       Mercury probably has none.
       Earth has the Goldilocks atmosphere.

F).  Relatively high density.
       Yes. 
       True of all the terrestrial planets.
       Earth is the most dense of all the planets.

What is the specific heat of an unknown substance if 2000 J of energy are required to raise the temperature of 4 grams of the substance 5 degrees Celsius?

Answers

The energy required to heat a substance is related by the formula:
Q = mCpΔT ; where Q is the energy, m is the mass of the substance, Cp is the specific heat capacity and ΔT is the change in temperature.
2000 = (4)(Cp)(5)
Cp = 100 Joules / g °C

An electron microscope is usually used for microorganisms that are _____. too small to be seen with the unaided eye too small to be seen with an optical microscope not possible to observe with any instrument

Answers

Answer;

too small to be seen with an optical microscope

Explanation;

  • An electron microscope is a type of microscope that is used to observe very tiny specimens whose features can not be observed by other types of microscopes. It uses a beam of electrons to generate an image of a given specimen whose features can be clearly observed and studied.
  • Electron microscope has very high resolution and magnification as compared to other optical microscope hence can be observed in the study of micro-organisms such as viruses which would be difficult to study their features using optical microscopes.

An electron microscope is usually used for microorganisms that are too small to be seen with the unaided eye. You can adjust the size of the microorganism to see it more clearly by adjusting its magnification lens. 

Which of the following helps support the argument that light behaves like a particle? A. Sound, which travels in waves, can't travel through a vacuum.
B. Interference is observed with light.
C. Diffraction is observed with light.
D. Unlike sound, light waves don't need a medium to self-propagate

Answers

The correct answer to the question is : D) Unlike sound, light waves don't need a medium to self-propagate

EXPLANATION:

Before coming into any conclusion, first we have to understand the nature of sound and light.

A sound wave is a longitudinal wave which requires a medium for its propagation.  It can not move in space as space contains no material medium for its propagation.

Light is normally considered as electromagnetic wave which does not require any medium for its propagation. It can travel in space also.

The interference and diffraction can not be explained by the particle nature of light.

Hence, the argument that partially support that light behaves just like a particle is the last statement i.e Unlike sound, light waves do not need a medium to self-propagate.

 Sound, which travels in waves, can't travel through a vacuum. 

As there is no matter in vacuum then sound cannot be transmitted. But the transmission of light is quite different, its particle and wave nature is well suited for travel in vacuum.

If you know the components of a vector, what mathematical relationship can be used to find the magnitude of the vector?

Answers

You will always use Pythagoras theorem to find magnitude while given components of vector.
No matter if system that you are observing is 2D or 3D or higher (which is imaginery) pythagoras theorem will be applied.

Formula for determining magnitude is:
M =  √(x^ + y^2 + z^2 + ...)

Number of turms inside square root you take depending on dimension of your system.

When the temperature of an object increases, what happens to the kinetic energy of the particles in the object? A.It is conserved.


B.It equals zero.


C.It increases.


D.It decreases.

Answers

When the average kinetic energy of the particles in the object increases, we sense and measure that change as an increase in the object's temperature.

A car leaves the pit after a refueling stop and accelerates uniformly to a speed of 62.2 m/s in 5.0 s to rejoin the race. What is the car's acceleration during this time?

Answers

Answer:

The car's acceleration is: a = 12.44 [m/s²]

Explanation:

To solve this problem we must use the following equation of kinematics.

v_(f) =  v_(o)+a*t

where:

Vf = final velocity = 62.2 [m/s]

Vo = initial velocity = 0 (because the car stars from the rest)

a = acceleration [m/s²]

t = time = 5 [s]

62.2 = 0 + a*5

a = 12.44 [m/s²]
