Caffeine = stimulant. So it adds to physiological arousal that stress can produce. It will increase heart rate, alertness, and insomnia in some people. It can decrease fatigue and improve concentration. If you have high stress or anxiety, caffeine would not be recommended.

<span>Caffeine stimulates your nervous system, which means too much can lead to a rapid heartbeat and increase in blood pressure. It can also irritate your digestive system. Additionally, excess caffeine can interfere with sleep and trigger dehydration, which can zap energy and cause headaches.</span>

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vecto
kupik [55]

Answer: rp/re= me/mp= 544 * 10^-6.

Explanation: To calculate this problem we have to consider the circular movement by the electron and proton inside a magnetic field.

Then the dynamic equation for the circular movement is given by:

Fcentripetal= m*ω^2.r

q*v*B=m*ω^2.r

we write this for each particle then we have the following:

q*v*B=me* ω^2*re

q*v*B=mp* ω^2*rp

rp/re=me/mp=9.1*10^-31/1.67*10^-27=544*10^-6

If T, = 40 N, find T, and the mass of the weight (W).
seraphim [82]

Answer:4kg

Explanation:

acceleration due to gravity(g)=10m/s^2

Weight(w)=40N

Weight=mass x g

40=mass x 10

Divide both sides by 10

Mass =40/10

Mass=4kg

The Sun produces 9.5 x 10^38 He atoms every second. Calculate the amount of energy produced by
Rama09 [41]

Answer:

You need to look up the figure for the energy released in the formation of one He atom, and then multiply that by the number of He atoms formed each second, and the result will be the total energy release that you seek.
