The net force simply the sum of two forces:
Negative and positive are assigned to those forces to show direction because it is a vector.
So, given that left is negative and right is positive;
<em>a)</em>
2.30N - .800N = 1.50 N
Given the equation F = ma, where m= 0.125 (mass) and F = 1.50 (force), we can solve for a (acceleration).
<em>b)</em>
1.50 N = (0.125 kg) a
a = 12.0 ms^-2

The application of a sufficiently strong magnetic field to a
superconductor will, in general, destroy the superconducting state. Two
mechanisms are responsible for this. The first is the Zeeman effect1, 2,
which breaks apart the paired electrons if they are in a spin-singlet
(but not a spin-triplet) state. The second is the so-called ‘orbital’
effect, whereby the vortices penetrate into the superconductors and the
energy gain due to the formation of the paired electrons is lost3. For the case of layered, two-dimensional superconductors, such as the high-Tc copper oxides, the orbital effect is reduced when the applied magnetic field is parallel to the conducting layers4.
Here we report resistance and magnetic-torque experiments on single
crystals of the quasi-two-dimensional organic conductor λ-(BETS)2FeCl4, where BETS is.

The trigonometric ratios are sine, cosine and tangent. We can use cosine to find the length of the shadow from the calculation as 1.7 ft.
<h3>What is trigonometric ratio?</h3>
The term trigonometric ratio has to do with sine, cosine and tangent which are used to solve problems that involve the right angled triangle.
Using the geometry of the right angle triangle, we can find the tangent of the angle 30 in order to obtain the length of the shadow.
Tan 30° = opp/3
opp = 3Tan 30°
opp = 1.7 ft
The length of the girl's shadow from the calculation is 1.7 ft.

Answer:
f_2 = 436 Hz
Explanation:
Given:
- Frequency of the note played f_1 = 440 Hz
- Number of beats heard per second b = 4 Hz
Find:
What was the frequency of the mis-tuned A string?
Solution:
- The beat is the difference in frequency of the notes played and is given by the expression:
| f_1 - f_2 | = beats
- we heard 4 beats, so
| f_1 - f_2 | = 4
- Plug in the value: | 440 - f_2 | = 4
Hence, f_2 = 436 Hz
