Answer:

The correct option is;

C. Computers involve matter and energy

Explanation:

The development of computers have been made by advancement and changes in the material components from which a computer is made such as the following;

a) The core material for the 1st generation of computers was vacuum tubes required for their operation

b) The 2nd generation of computers had the vacuum tubes replaced with transistors

c) The 3rd generation of computers worked with integrated circuits

d) The 4th generation which is the present day generation of computers make use of the microprocessor which consists of several thousand integrated circuits located in one silicon chip

As such the development of computers involves discovering new methods of suitable and applicable material usage

The properties of these components are naturally studied by physicists and the the future generation of computers that represent a quantum leap is more likely based on improvement in a combination of material and energy usage which are the main core areas of the study of physics

The physicist is as observed, one of the most, important member of a computer design and manufacturing team.

The bob (weight) at the end of a pendulum has a mass of 0.3 kilograms. The bob is pulled to position B and allowed to swing. It

Ivahew [28]

Answer:

0.147 J

Explanation:

The total energy that has been transformed into thermal energy is equal to the loss of gravitational potential energy between the initial situation (bob at h=0.5 m above the ground) and the final situation (bob back but at h=0.45 m above the ground).

Therefore, we have

$E_{thermal}=\Delta U=mgh_1 - mgh_2 = mg(h_1 -h_2)$

where

m = 0.3 kg is the mass of the bob

g = 9.8 m/s^2

h1 = 0.5 m is the initial height

h2 = 0.45 m is the final height

Substituting, we find the thermal energy

$E_{thermal}=(0.3 kg)(9.8 m/s^2)(0.5 m-0.45 m)=0.147 J$

Therefore, the energy transformed into thermal energy is 0.147 J.

A and B start walking in the same direction at the same time around a circular park of diameter 4200 m. If A walks 10 m more tha

Liono4ka [1.6K]

Answer:

Va = 5000 m / 3600 s = 1.39 m/s

(Va - Vb) 60 = 10

Vb = Va - .167 = 1.22 m/s

(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap

.17 T = 4200 Π

T = 24700 Π time for A to again catch B

N = 1.39 * 24700 Answer:

Va = 5000 m / 3600 s = 1.39 m/s

(Va - Vb) 60 = 10

Vb = Va - .167 = 1.22 m/s

(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap

.17 T = 4200 Π

T = 24700 Π time for A to again catch B

N = 1.39 * 24700 Π / (4200 Π) = 8.2 laps

A will make 8 but not 9 rounds before catching B
