Answer:
3189.07Pa
Explanation:
The conversion of 23.92mmH to Pa can be achieved in the following way:
760mmHg = 101325Pa
23.92mmHg = (23.92x101325)/760 = 3189.07Pa
My answer -
A nuclear reactor produces and controls the release of energy from splitting the atoms of uranium.
Uranium-fuelled nuclear power is a clean and efficient way of boiling
water to make steam which drives turbine generators. Except for the
reactor itself, a nuclear power station works like most coal or
gas-fired power stations.
P.S
Happy to help you have an AWESOME!!! day ^-^
The density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³
<h3>What is Density ?</h3>
Density is the measurement of how tightly a material is packed together.
It is defined as the mass per unit volume.
Given ;
- Mass = 23.5 g
- Volume = 13.5 cm³
Formula to calculate density ;
Density = mass / volume
=23.5 / 13.5 = 1.74 g/cm³
Hence, the density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³.

Answer:
3,2,5,1,4
Explanation:
A chemical synapse begins when an (3)<em>action potential reaches the axon terminal depolarizing the membrane</em> leading to the opening of the voltage-gated Na+ channels, this Na+ ions will then depolarize the presynaptic membrane, opening the voltage-gated Ca2+ channels. (2)<em>Calcium ions then will initiate a cascade entering the neuron </em>that will lead to the fusion of synaptic vesicles with the presynaptic membrane (5)<em>causing the releasing of neurotransmitters into the synaptic cleft.</em> (1)<em>These neurotransmitter will diffuse across the synaptic place in order to bind to the receptors on the postsynaptic membrane,</em> (4)<em>particulary into the ligand-gated channels, opening them.</em>

Answer:
What will happen to Uk if you double the mass?
Explanation:
Uk = 0.5 * m * v²
You see that both m and v are variable, which means that both m and v can be any number. Regardless of the numbers you put in for m or v, the formula to calculate the kinetic energy (Uk) remains valid.
You could ask
1. What will happen to Uk if you double the mass?
2. What will happen to Uk if you double the velocity?
please see and understand(!) that the relationship between Uk an v² is indeed the velocity squared....
EXTRA
Uk = 0.5 * m * (v)²
Suppose the m = 3kg and velocity = 5 m/s
What is the Uk?
Well if you know the formula you can use your calculator to find out:
Uk = 0.5 * m * (v)²
Uk = 0.5 * 3 * (5)²
Uk = 0.5 * 3 * 25
Uk = 37.5 kgm/s²
Again you ask what will happen to Uk if you double the velocity?
At first it was 5 m/s and now it doubles, which means it now has that value *2
The new velocity is 5 *2 = 10 m/s
Uk = 0.5 * m * (v)²
Uk = 0.5 * 3 * (10)²
Uk = 0.5 * 3 * 100
Uk = 150 kgm/s²
150 = 4 * 37.5
So now you see that if you double your velocity, the Uk will be 2² = 4 times as big !
