Answer:
f=1.59 Hz
Explanation:
Given that
Simple undamped system means ,system does not consists any damper.If system consists damper then it is damped spring mass system.
Velocity = 100 mm/s
Maximum amplitude = 10 mm
We know that for a simple undamped system spring mass system
now by putting the values
100 = ω x 10
ω = 10 rad/s
We also know that
ω=2π f
10 = 2 x π x f
f=1.59 Hz
So the natural frequency will be f=1.59 Hz.
Answer:
There is a yellow line on your left and a white line on your right.
Explanation:
The yellow line between the roads separate the oncoming traffic lane, so the drivers won't get confused. Since the driver is on the right side of the road, the yellow line would be on their left, since the middle line (yellow line) is in the middle of the road.
Answer:
C. Welded contacts on the thermostat
Explanation:
Any fault that keeps the heating element heating when it should not is a fault that will cause the symptom described. The details <em>depend on the design of the brewer</em> (not given).
"A short at the terminals" depends on what terminals are being referenced. The device on-off switch terminals are normally connected together when the brewer is turned on, so a short there may not be observable.
"Welded contacts on the thermostat" will have the observed effect if the thermostat is the primary means of ending the brewing cycle. If the thermostat of interest is an overheat protective device not normally involved in ending the brewing cycle, then that fault may not cause the observed symptom.
__
If the heating element is open-circuit, no heating will occur. A gasket leak may cause a puddle, but may have nothing to do with the end of the brewing cycle. (Loss of water can be expected to end boiling, rather than prolong it.)
Answer:
4
Explanation:
A "board foot" is 1/12 of a cubic foot. It is the volume of a board 1" thick and 1 foot square.
Here, the board is 1" thick, so the number of board feet is numerically equal to the number of square feet of area it has.
(1/2 ft)(8 ft) = 4 ft²
The number of board feet is 4.
Answer:
Both of them
Explanation:
When creating a marketing plan you need to think of the objective or goals that you have, you should probably always have a running campaign to help the brand itself to be constantly seen by the audience, while at the same time having specific campaigns for the products that you want to push or to promote the most. For example, not all of Nike's ads are aimed to sell more sneakers or sports clothing, some of them are just to keep them on the conversation and growing their brand, while the hype up campaign for the release of a new pair of sneakers or collection is done at the same time. So you should always go for both.
