Torque can be calculated by multiplying the force (N) applied at 90∘ to the lever arm at a distance (m) from the pivot point (po

For areas labeled X, Y, and Z, X is only attractive, Y has a very limited range, and Z is both attractive and repulsive. In the earlier provided information, Anna created a diagram to compare forces that are either strong or weak. The aim is to identify the labels belonging to the areas designated as X, Y, and Z respectively. Therefore, for X, Y, Z, it is categorized as: X: strictly attractive or attractive only, Y: extremely limited range, Z: contains both repulsive and attractive characteristics.

Intense activity and magnetic fields are manifested by features, with sunspots occurring that are vastly larger than those seen on the Sun. These cause disturbances in the star's spectrum that exceed those produced by planets, rendering them significantly more difficult to detect, even in cases of hot Jupiters.

Answer:

3.4 x 10⁴ m/s

Explanation:

Analyze the circular path of the electron

B = magnetic field = 80 x 10⁻⁶ T

m = mass of an electron = 9.1 x 10⁻³¹ kg

v  = speed in the radial direction

r = radius of the circular trajectory = 2 mm = 0.002 m

q = charge of an electron = 1.6 x 10⁻¹⁹ C

For the electron’s circular movement

qBr = mv

(1.6 x 10⁻¹⁹) (80 x 10⁻⁶) (0.002) = (9.1 x 10⁻³¹) v

v = 2.8 x 10⁴ m/s

Now, consider the electron's movement in a straight line:

v' = speed in linear motion

x = distance traveled horizontally = 9 mm = 0.009 m

t = duration = = = 4.5 x 10⁻⁷ sec

Using the formula

x = v' t

0.009 = v' (4.5 x 10⁻⁷)

v' = 20000 m/s

v' = 2 x 10⁴ m/s

The resultant speed is given by

V = sqrt(v² + v'²)

V = sqrt((2.8 x 10⁴)² + (2 x 10⁴)²)

v = 3.4 x 10⁴ m/s
