Answer : Energy equivalent of an object with a mass of 2.5 kg is $E=2.25\times 10^{17}\ J$ .

Explanation :

It is given that mass of an object is, m = 2.5 kg

It is required to find energy equivalence.

According to mass energy equivalence relation :

$E=mc^2$

Where,

m is the mas of an object.

c is the speed of light $c=3\times 10^8\ m/s$

$E=2.5\ kg\times (3\times 10^8)^2\ m/s$

$E=22.5\times 10^{16}\ J$

$E=2.25\times 10^{17}\ J$

Hence, this is the required solution.

A study occasionally the effect of anxiety (low vs. high) and stress (low vs. moderate vs. high) on test.

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 health. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are getting ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, pupils with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have occasionally that female students have greater levels of test anxiety than male students.
