Answer:
Limitation in the level of possible accuracy of the that can be obtained to mainly whole degrees
Explanation:
The angle measurement values are located around the circularly shaped bevel protractor to which a Vernier scale can be attached to increase the accuracy of the angle measurement reading
The accuracy of the bevel protractor is up to 5 arc minutes or 1/12° with the space on the Vernier scale having graduations of 1/12°, such that two spaces on the main scale is 5 arc minutes more than a space on the Vernier scale and the dimensions of the coincidence of the two scale will have an accuracy of up to 1/12°
Therefore, whereby the Vernier scale is damaged, the accuracy will be limited to the accuracy main scale reading in whole degrees.
Answer:
The block will float with its axis vertical.
Explanation:
For it to float, the upward force on the cylindrical block must be equal to the weight of an equal volume of water. Also, this upward force must be greater than or equal to the weight of the cylindrical block for it to float.
So, weight of cylindrical block, W = specific weight × volume
specific weight = 7500 N/m³
volume = πd²h/4 where d = diameter of block and h = height of block
volume = π(1 m)² × 1 m/4 = π/4 m³ = 0.7854 m³
W = 7500 N/m³ × 0.7854 m³ = 5890.5 N
Since the density of water = 1000 kg/m³, its specific weight W' = 1000 kg/m³ × 9.8 m/s² = 9800 N/m³
Since the volume of the cylinder = volume of water displaced, the weight of water displaced W' = upward force = specific weight of water × volume of water displaced = 9800 N/m³ × 0.7854 m³ = 7696.92 N
Since W' = 7696.92 N > W = 5890.5 N, <u>the block will float with its axis vertical since the upward force is greater than the weight of the cylindrical block.</u>
Answer:
C. Primary auxiliary view
Explanation:
A secondary auxiliary view is obtained by projecting the primary auxiliary view to the plane which lies perpendicular to the true (complete) edge length of the primary auxiliary view. In the secondary auxiliary view, the sides that come after the closer edges of the primary auxiliary view becomes visible making it appear that the side after the closer edge is the visible top of the view
Therefore, the drawing necessary for him to create the secondary auxiliary view is the <em>primary auxiliary view.</em>
The designers suggest that speech recognition allows for spoken interaction or conversation and spoken prompts or commands.
Explanation:
The speech recognition is used when the user has physical impairments and hands are busy, eyes are occupied and the user cannot read.
We can save time with the usage of speech recognition system. The users are knowledgeable based on the actions available.
The problems faced in speech recognition system are in the noisy environment it has bad microphones and the commands should be learned and remembered.
The other obstacle is error correction is time consuming. the speech production has slow space to speech output provides privacy in public spaces. The disadvantage is it contains large amount of information.
