We are trying to reduce the current time of 15s by 30% but this leads to an increase of 18% in the CPI. For each processor, what

clock rate should we have to achieve this time reduction?

Answer:

Explanation:

For reduction

Execution time = (instructions * CPI)/(Clock rate)

Since CPI is increased by 18%

18/100 +1 = 1.18

Therefore

P1 CPI = CPI x 1.18

P2 CPI = CPIx 1.18

P3 CPI = CPI x 1.18

Since clockrate reduces by 30% we have it to be a 0.7

P1: (Instructions x P1CPI) / 0.7

P2: (Instructionsx P2CPI) / 0.7

P3: (Instructions x P2CPI) /0 .7

An aluminum wire is 5.87 m long and has a diameter of 6.07 mm.
antoniya [11.8K]

Answer: 5.72 x 10-3Ω

Explanation:

Hi, to answer this question, first we have to calculate the cross sectional area of the cable:

Diameter (D)=6.07 mm

Since: 1000mm = 1m

6.07mm/ 1000mm/m = 0.00607 meters

Area of a circle : π (d/2)^2

A = π (0.00607/2)^2= 0.000028937 m2

Resistance formula:

Resistance (R) = P(resistivity) L (length)÷A (cross sectional area )

Replacing with the values given:

R = (2.82x10-8 x 5.87) / 0.000028937

R = 5.72 x 10-3Ω

Feel free to ask for more if needed or if you did not understand something.

A mass m is attached to a string connected to a force sensor on a rotating platform. The platform’s angular velocity, ω, can be
makkiz [27]

Answer:

The mass m is 0.332 kg or 332 gm

Explanation:

Given

The platform is rotating with angular speed , \omega =8.5\, \frac{rad}{sec}

Mass m is moving on platform in a circle with radius , r=0.20\, m

Force sensor reading to which spring is attached , F=4.8\, N

Now for the mass m to move in circle the required centripetal force is given by F=m\omega ^{2}r

=>4.8=m\times 8.5 ^{2}\times 0.20

=>m=0.332\, kg

Thus the mass m is 0.332 kg or 332 gm

We have no idea.  There are probably many things involved ... the planet's mass,
the availability of small bodies in the neighborhood that can be captured, etc.
