Answer:

Option C

Explanation:

Given:

- Clock speed f = 33 MHz

- The width of the bus w = 32 bits

Find:

what is the theoretical throughput in MiBytes?

Solution:

- First step is to convert the width of the bus to bytes as follows:

                                 Bytes = 32 bits * (1 Bytes / 8 bits)

                                 Bytes = 32 / 8

- Second step is to evaluate the time of the cycle:

                                 Time period of clock T = 1 / f

                                 Time period of clock T = 1 s / (33*10^6)  

                                                                     T = (1 / 33*10^6)

- Third step is to formulate the number of byte:

                                 Number of byte = Bytes * T

                                                             = (32 / 8*33*10^6)  

- Fourth step is to convert to Mi bytes:

                                 Mibytes = Number of byte / 2^20

                                 Mibytes = (32 / 8*33*10^6 * 2^20)

- The correct option is C

The third floor of a house is 8m above street level. How much work is needed to move a 136kg refrigerator to the third floor?
jonny [76]

m = Mass of the refrigerator to be moved to third floor = 136 kg

g = Acceleration due to gravity by earth on the refrigerator being moved = 9.8 m/s²

h = Height to which the refrigerator is moved  = 8 m

W = Work done in lifting the object

Work done in lifting the object is same as the gravitational potential energy gained by the refrigerator. hence

Work done = Gravitation potential energy of refrigerator

W = m g h

inserting the values

W = (136) (9.8) (8)

W = 10662.4 J

PLS HELP<br><br> compare longitudinal and transverse waves
babymother [125]
<span>A transverse wave is one for which the direction of oscillation is perpendicular to the direction of propagation of the wave whereas, for longitudinalwaves oscillations are in the direction of propagation. Ripples in pond water move about the surface of water and they simultaneously move away from the point-0 too.</span><span>
Longitudinal waves include sound waves(vibrations in pressure, particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of thewave.

A 13-kg sled is moving at a speed of 3.0 m/s. At which of the following speeds will the sled have twice as much kinetic energy?
AysviL [449]
K.E. = 1/2 mv²
K.E. is directly proportional to v^2
So, when K.E. increase by 2, K.E. increase by root. 2
v' = 1.41v
original v value was 3 so, final would be:
v' = 1.41*3 = 4.23
After round-off to it's tenth value, it will be:
v' = 4.2

So, option B is your answer!

Hope this helps!

A leaf fell from a tree branch. The path it followed is shown in the diagram below.
prisoha [69]

The leaf fell at the crooked path instead of straight down because air currents and gravity applied changing and unbalanced forces to the leaf.

<h3>What is an air current?</h3>

An air current is defined as the changes in atmospheric pressure that causes the movement of air from one area to another.

When a leaf is detached naturally from the tree, it won't fall straight down to the floor but will fall a distance away from the tree due to the action of air current and some unbalanced forces.
