Answer:
Potential difference = 245 V
Explanation:
First, we have to find velocity at which ionized molecules are accelerated into a magnetic field. Here, magnetic force acts as a centripetal force due to circular path of molecules towards detector slot.
- B= 0.25 T,d= 12 cm
- mass = (12+16+16)×1.67×10-27kg
Now, the magnetic force to the centripetal force equates as:
qvB = =
For Velocity (v) :
v =
According to law of conservation of energy, we know that the initial potential energy of the molecules is converted into kinetic energy as they enter into the magnetic field. So,
Substitute the value of v in above equation:
qV = m
V =
V= 245 V
I’m sorry but i don’t see an attachment of choices or anything

Answer:
the inductive reactance of the coil is 1335.35 Ω
Explanation:
Given;
inductance of the coil, L = 250 mH = 0.25 H
effective current through the coil, I = 5 mA
frequency of the coil, f = 850 Hz
The inductive reactance of the coil is calculated as;
Therefore, the inductive reactance of the coil is 1335.35 Ω
The average value for t- statistics is 0 if null hypothesis is true.
What is a t – statistics and null hypothesis ?
- The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesized value relative to its standard error.
- Through the Student's t-test, it is utilized in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis.
- It is quite comparable to the z-score, but when the data is small or the standard deviation is unknown, the t-statistic is employed instead.
- The default assumption, or null hypothesis, is that the quantity being measured is zero (null). The quantity to be assessed is often the difference between two circumstances.
- Trying to determine, for instance, whether there is conclusive evidence that an impact has happened or that samples come from several batches
The t-test yields a t-value of 0 if the sample data precisely match the null hypothesis. The value of the t-value rises as the sample data diverge more and more from the null hypothesis.
