So, the weight is supported by the tension in the two wires, but only part of the tension goes in holding the body: the vertical component.
If the angle between the ceiling and the wire is 40 deg, then the vertical component is
T_y = T * sin(40),
There are two wires, so together they do
2*T*sin(40)
And all this holds the weight of the body, so:
2*T*sin(40)=150 ----> T = 75/sin(40)~116.68 N,
Notice how it is larger than 150N (both wires is ~ 233 N), as the angle becomes smaller, there is less tension that is vertical, so one needs more tension to make the vertical component as large as (half) the weight of the body
Hope it helps!
Answer:
Option A
Explanation:
At segment T-U, the substance changes from a liquid to a gas and does not change temperature.
The reason is because latent heat of vaporisation allows for the absorption of heat in the change of state and temperature remains constant until it has fully changed state.
Answer:
B
Explanation:
Millions of dollars have been made from those visitors.
The answer is D because the mass of H is 1.008 and the mass of Cl is 35.45. When added up the answer is around 36.458. Depending on your periodic table and number of significant figures the values would be different slightly. 36.458 is pretty close to 36.46094 compared to other answers. Hope this helps!
Answer:
Uninvolved parenting style
Explanation:
Uninvolved parenting style is the parenting style which is thought to produce children who grow up to be emotionally withdrawn, distant, and lacking in curiosity.
This is usually because there is little or no contact between the parents and children which leaves a wide gap and the children start to become emotionally withdrawn as a result. They also aren’t curious to learn new things as a result of the absence of parental care.
