An antiproton is identical to a proton except it has the opposite charge, −e. To study antiprotons, they must be confined in a
Zigmanuir [339]

Answer:

Explanation:

We know that, the force responsible for circulating in circular path is the centripetal force given by the force on charged particle due to magnetic field.

Here the charge is antiproton is

p = -1.6 * 10⁻¹⁹C

the speed of proton is given by 1.5 * 10 ⁴ m/s

the magnetic field is B = 4.5 * 10⁻³T

we have force due to magnetic field is equal to centripetal force

Bqv = mv² / r

Bq = mv / r

r = \frac{mv}{Bq} \\\\r=\frac{mv}{Bq} \\\\r=\frac{1.67 \times 10^-^2^7\times 1.5 \times 10^4}{4.5 \times 10^-^3\times 11.6\times 10^-^1^9} \\\\r=347.9\times 10^-^4\\\\r=3.479cm

The diameter d of the vacuum chamber have to allow these antiprotons to circulate without touching the walls is

d = 2r

d = 2 * 3.479

d = 6.958

d ≅ 7cm

Calculate the resulting speed of an airplane with an airspeed of 120 km/h pointing due north when it encounters a wind of 90 km/
STatiana [176]

Answer:

The resulting speed of the airplane is 150 Km/h

Explanation:

The airspeed of the plane is 120 Km/h due North. The wind came from West pointing to the East at 90 Km/h

Both speeds are acting in different directions, so they must be added as vectors. Both vectors and the resulting velocity (Vr) are shown in the image below

The magnitude of that velocity can be computed by using Pythagoras's theorem:

Vr^2=120^2+90^2

Vr^2=14400+8100=22500

Vr=\sqrt{22500}=150

The resulting speed of the airplane is 150 Km/h
