A study assessing the effect of anxiety Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound.
Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have negative effects on our physical spherical. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are spherical ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, spherical with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.

Maybe, but she hasn't proved it yet. As another example, somebody may bring a jar of gas to your laboratory, and you test the gas in the jar and you find nitrogen atoms, oxygen atoms, argon atoms, and krypton atoms, and there isn't a single compound in it. The gas in the jar is a MIXTURE of gases . . . a mixture that we call "Air".
In order for magma to form, wet or dry melting of rocks or minerals must occur. Dry melting occurs when minerals or rocks, with no carbon dioxide or water in them, are heated to a specific temperature.
Answer:
The time is 2.8 ms.
Explanation:
Given that,
Capacitor = 0.12 μF
Resistance = 10 kohm
Voltage = 12 V
Charge Q = 0.9 Q₀
We need to calculate the time constant
Using formula of time constant

Put the value into the formula


We need to calculate the time
Using formula of time

Put the value into the formula




Hence, The time is 2.8 ms.
Answer:
the ratio of the heat rejected to the cold reservoir for the improved engine to that for the original engine is 0.68
Explanation:
Given information
initial efficiency, η
= 0.28
final efficiency, η
= 0.51
ratio of the heat rejected = (1 - η
)/(1 - η
)
= (1 - 0.51)/(1 - 0.28)
= 0.68
