X-rays have the shortest wavelength.
Hope this helped,, have a great day! :D
True, scientists often talk to each other to figure out if their results were similar and what they could have done better.
Although, talking to other scientists does have risks, other scientists could copy your work and further better it.
So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol
Answer:
27.5Ω
Explanation:
Given parameters:
Potential difference in the circuit = 11V
Current in the circuit = 0.4A
Unknown:
Resistance in the circuit = ?
Solution:
According to ohm's law;
V = IR
V is the voltage
I is the current
R is the resistance
Since the unknown is R, we find it;
11 = 0.4 x R
R = = 27.5Ω
Answer:
The work done by the force is 6μJ
Explanation:
Suppose, A 30 nC charge is moved from a point where V₁ = 130 V to a point where V₂ = -70 V.
We need to calculate the work done by the force
Using formula of work done
Where, q = charge
=potential difference
Put the value into the formula
Hence, The work done by the force is 6μJ.
We determine the rate of a reaction from the given rate law by substituting the given concentrations and the order of the substances. We calculate as follows:
<span>rate = k[A]^m[B]^n
</span><span>rate = (1 x 10^-2) [2]^2 [3]^1
rate = 0.12 M /s
The rate law of a reaction is an expression that is related to the reaction rate. The parameters used are the concentration or the pressure of the reactants in the reaction. An example would be:
</span><span>
A = B + C
The rate law would be:
Rate = k[A] where k is the reaction rate constant and determined by doing experiments</span>
