Explanation:
<h2>the velocity has decreasing velocity. this is my answer</h2>
The answer is Solvent. The reason is in the wording, 'the substance that does the dissolving.' A solvent does the dissolving, a solute is something that can be dissolved.
he speed of sound can travel faster in hot air than it can in cold air.
I think the correct answer is a series circuit. This type of circuit is characterized by having only one path for electric current to flow. All of the components in the circuit share the same current. Hope this answers the question. Have a nice day.
Answer:
T = 243.80 N
Explanation:
In order to calculate the tension T in each of the cables, you take into account the Newton second law for the vertical component of the forces involved.
(1)
where you have used the fact that both cables have the same tension T, and they make the same angle with the horizontal.
W is the weigh of the loudspeaker and has the folowing values:
Next, you can calculate the angle θ by using the information about the length of the cables and the distance from the ceiling to the loudspeaker:
Finally, you solve the equation (1) for T, and then you replace the values of the other parameters:
The tension in each cable is 243.80N
