Which of the following statements best characterizes the surface of the planet Mars?The surface of Mars is continuously resurfac

ed by ongoing volcanic activity; consequently, there are almost no visible impact craters.All the big volcanoes are in the northern hemisphere of Mars, and most of the craters are in the southern hemisphere.Eighty percent of the surface of Mars is rolling plains, with a number of major volcanoes and only two continent-sized uplands.On Mars there are several moving lithospheric plates rimmed by long mountain chains, deep subduction trenches, and several large rift valleys.

If an atom has 15 protons, 12 neutrons, and 17 electrons, what is the atom's electrical charge? A. -5 B. -2 C. +3 D. +5
Nimfa-mama [501]

Answer:

B. -2

Explanation:

The total charge on an atom is the sum of all individual charges present in it. Therefore, the total charge on this atom is given by the following formula:

q = (n_p)(q_p)+(n_e)(q_e)+(n_n)(q_n)

where,

q = total charge on atom = ?

n_p = no. of protons in the atom = 15

n_e = no. of electrons in the atom = 17

n_n = no. of neutrons in the atom = 12

q_p = charge on proton = +1

q_e = charge on electron = -1

q_n = charge on neutron = 0

Therefore,

q = (15)(1)+(17)(-1)+(12)(0)\\q=-2

Hence the correct option is:

<u>B. -2</u>

Bats use a process called echolocation to find their food. This involves giving out sound waves that hit possible prey or food.
cupoosta [38]
The type of waves used by bats are sound waves. Most of the species use their larynx to produce ultrasound waves in the frequency range of 20 to 200 kilohertz.
These sound waves are echoed, reflected, by surroundings, in this case food or prey. These reflections are received by the specialized receptor cells in the ears of bats. The reflections are analyzed by the brain to make an image.
Fun fact: The brain cells of bats are also specialized to better analyze the frequency of ultrasound used by the bat.
