Answer:
23.67 m
Explanation:
We are given;
Frequency; f = 0.3 Hz
Speed; v = 7.1 m/s
Now, formula to get the wavelength is from the wave equation which is;
v = fλ
Where λ is wavelength
Making λ the subject, we have;
λ = v/f
λ = 7.1/0.3
λ = 23.67 m
Answer:
Ft = 0[N]
Explanation:
To understand this problem we must perform an analysis of forces on the X axis, which coincides with the axis of forces of dogs.
In this way performing a sum of forces on the X-axis we will have (newton's third law):

From this analysis we can see that the resulting or total force is equal to zero, since there is no movement.
_dThe radius of curvature of a subatomic particle under a magnetic field is given by the following formula:

Where:

We can determine the quotient between the velocity and the charge of the deuteron particle from the formula. First, we divide both sides by the mass:

Now, we multiply both sides by the magnetic field "B":

Since the charge of the deuterion is the same as the charge of the proton and the velocity we are considering are the same this means that the quotient between velocity and charge is the same for both particles. Therefore, we can apply the formula for the radius again, this time for the proton:

And substitute the quotient between velocity and charge:

Now, we cancel out the magnetic field:

Now, we substitute the values:

Solving the operations:

Therefore, the radius is 19.3 cm.
