The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω
Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.
Complete question:
A diver is 10 m below the surface of water. Calculate the pressure the fluid exerted on the diver. The acceleration of gravity is 9.8 m/s2 and the density of the water is 1000 kg/m3. Answer in units of Pa. Show your work.
Answer:
Tthe pressure the fluid exerted on the diver is 1.99 x 10⁵ Pa
Explanation:
Given;
density of water, ρ = 1000 kg/m³
diver's position below the surface of the water, h = 10 m
acceleration due to gravity, g = 9.8 m/s²
Let the atmospheric pressure, P₀ = 101325 Pa
The pressure 10 m below the surface of the water is calculated as;
P = P₀ + ρgh
P = 101325 Pa + (1000 x 9.8 x 10)Pa
P = 199325 Pa
P = 1.99 x 10⁵ Pa.
Therefore, the pressure the fluid exerted on the diver is 1.99 x 10⁵ Pa
The answer is B! Hope this helps
Answer:
Ammonia, 
Explanation:
If a Rac variant, in which the residue at position 61 was replaced with an alanine (Rac-61A), was synthesized. Also, Wild-type Rac and Rac-61A were incubated separately with VopC.
In order to obtain data to support that VopC modifies Rac at residue 61, the samples should be analyzed for the presence of Ammonia (![NH_{3}[\tex]) compound.In chemistry, the Vanadyl Phthalocyanine (VopC) comprises of a catalytic domain that activates host cells GTPase Rac irreversibly, through the deamide side chain of the residue existing at position 61.Also, we know that a deamidation reaction gives off Ammonia, [tex](NH_{3})](https://tex.z-dn.net/?f=NH_%7B3%7D%5B%5Ctex%5D%29%20compound.%3C%2Fp%3E%3Cp%3EIn%20chemistry%2C%20the%20Vanadyl%20Phthalocyanine%20%28VopC%29%20comprises%20of%20a%20catalytic%20domain%20that%20activates%20host%20cells%20GTPase%20Rac%20irreversibly%2C%20through%20the%20deamide%20side%20chain%20of%20the%20residue%20existing%20at%20position%2061.%3C%2Fp%3E%3Cp%3EAlso%2C%20we%20know%20that%20a%20deamidation%20reaction%20gives%20off%20Ammonia%2C%20%5Btex%5D%28NH_%7B3%7D%29)
and as such when ammonia is present in the sample containing Wild-type Rac but not in Rac-61A, this simply proves or provide the data to support that VopC modifies Rac at residue 61.
<em>Additionally, deamidation can be defined as the chemical conversion (hydrolysis) of an amide functional group such as glutamine, asparagine, in a polypeptide to another functional group such as glutamic acid or isoaspartic acid respectively by treating it with a strong acid (deamidate, transamidase). </em>
Answer:
198.2°
Explanation:
The angle from the +x axis can be found with:
θ = atan(vy / vx)
Given vx = -7.55 and vy = -2.48:
θ = atan(-2.48 / -7.55)
θ = 18.2°, 198.2°
Since θ is in the third quadrant, θ = 198.2°.
