Our favorite program runs in 10 seconds on computer A, which has a 4 GHz. clock. We are trying to help a computer designer build

Alona [7]

Answer:

The rate clock is about

F = 8 GHz

Explanation:

f₁ = 4 G Hz , t₁ = 10 s , t₂ = 6s , f₂ = 1.2 f₁

Can organize to find the rate clock the designer build to the target so

X / 4 Ghz = 10 s , 1.2 X / Y = 6 s

X * Y = 10 s ⇒ F = 10 s

1.2 * 4 G Hz = 6 s

F = 10 * ( 1.2 * 4 G Hz ) / 6

F = 10 * ( 1.2 * 4 x 10 ⁹ Hz ) / 6

F = 8 x 10 ⁹ Hz

F = 8 GHz

A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.

zzz [600]

Answer:

a) B = 0.9375 T -z, b) B = 1.54 T

Explication

a) The magnetic force is

F = q v x B

f = q v B sin θ

bold indicates vectors

For direction let's use the right hand rule.

If the charge is positive

the flea in the direction of velocity, toward + x

the fingers extended in the direction of B

the palm the direction of the force + and

therefore the magnetic field goes in the direction of -z

F = q v B

2.25 10-16 = 1.6 10-19 1.50 103 B

B = 2.25 10-16 / 2.4 10-16

B = 0.9375 T -z

b) now an electron

thumb speed direction, -z

opposite side of palm force + y

therefore the direction of the magnetic field is + x

B = F / qv

B = 8.5 10-16 / 1.16 10-19 4.75 103

B = 1.54 T
