What is the magnitude of g at a height above Earth’s surface where free- fall acceleration equals 6.5 m/s2 ?
satela [25.4K]
Well, the "magnitude of g" in a place is always described as the
free-fall acceleration there.  So your ' 6.5 m/s² ' is the answer to
the question.

Which of the following solutions will have the lowest freezing point?
gregori [183]
 C. 1.0 mol/kg sodium phosphide (Na3P)<span> 

This is because it will produce 4 ions, and thus has the highest molalitiy. (more particles in solution lowers the freezing point) 

</span><span>remember if you ever need anything and you dont want to waste points you can just post it on my pfp or message me the question</span>

Light is shone on a diffraction grating
Pani-rosa [81]

Answer:

    λ = 482.05 nm

Explanation:

The diffraction phenomenon and the diffraction grating is described by the expression

         d sin θ = m λ

where d is the distance between two consecutive slits, λ the wavelength and m an integer representing the order of diffraction

in this case they indicate the distance between slits, the angle and the order of diffraction

         λ = \frac{d sin \theta }{m}d sin θ / m

let's calculate

         λ = 1.00 10⁻⁶ sin 74.6 / 2

         λ = 4.82048 10⁻⁷ m

Let's reduce to nm

         λ = 4.82048 10⁻⁷ m (10⁹ nm / 1 m)

         λ = 482.05 nm

In the terminal portion of the axon (i.e. the end of the nerve) at the neuromuscular junction, calcium ions act to _________.
valentinak56 [21]

Answer: TO RELEASE SYNAPTIC VESICLES FROM THE AXON TERMINAL.

Explanation: SYNAPTIC VESICLES are in the form of sack,which helps in the storage of Neurotransmitters. Neurotransmitters are released from the SYNAPSES through the Calcium channels which highly depend on Voltage.

Vesicles are essential for transmitting nerve impulses from one neuron to another Vesicles are constantly recreated by the cell as some older ones age.
