An ion in a mass spectrometer follows a semicircular path of radius 14.8. What is the distance it travels?

2 answers:

7 0

The circumference of a circle is (2π · the circle's radius).

The length of a semi-circle is (1π · the circle's radius) =

(π · 14.8) = 46.5 (rounded)

(The unit is the same as whatever the unit of the 14.8 is.)

An electron that has a velocity with x component 2.6 × 106 m/s and y component 2.4 × 106 m/s moves through a uniform magnetic fi

Scrat [10]

Answer with Explanation:

We are given that

$v_x=2.6\times 10^6 m/s$

$v_y=2.4\times 10^6 m/s$

$B_x=0.029 T$

$B_y=-0.14 T$

a.We have to find the magnitude of the magnetic force on the electron.

$v\times B=\begin{vmatrix}i&j&k\\2.6\times 10^6&2.4\times 10^6&0\\0.029&-0.14&0\end{vmatrix}$

$v\times B=(-0.364-0.0696)\times 10^6 k=-0.4336\times 10^6 k$

Charge on an electron,q= $-1.6\times 10^{-19} C$

$F=q(v\times B)=\mid -1.6\times 10^{-19}(-0.4336)\times 10^6\mid =6.9\times 10^{-14} N$

Force act along positive z- direction.

b.Charge on proton= $q=1.6\times 10^{-19} C$

$F=\mid 1.6\times 10^{-19}(-0.4336)\times 10^6\mid =6.9\times 10^{-14} N$

Name two devices we use generators in. Describe how they work.

Firlakuza [10]

Answer:

There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.

Explanation:

An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.
