Answer:
Planning and performing an experiment to answer the question.
Explanation:
There are two possible answers:
<span>- it can move out to a higher electron shell
- </span><span> it can stay in its original shell
</span><span>
In fact, sunlight consists of photons. When sunlight hits an electron, the electron can absorbs a photon, so it gains energy: as a result, the electron can move to a higher electron shell, which corresponds to a high energy level in the atom, if the energy given by the photon is at least equal to the energy difference between the two levels. However, if the photon energy is not large enough, the electron will stay in the same shell.</span>
Answer:
The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
<span>Gvn that,
Radius r = 1.65cm
then the Diameter d = 3.3 cm
Volume V = 4/3pi*(D/3)^3
= 4/3*3.14*(3.3)^3/8
= 4/3*3.14*35.937/8
= 4/3*3.14*4.492125
= 4/3*14.1052725
= 56.421.9/3
= 18.80703 dm^3
We know that gravity g=9.806m/s^2
p pt = 2.14 * 104 kg/m^3 = 21.4
p hg = 1.36 * 104 kg/m^3 = 13.6
Real Weight Wr = V*p pt*g
= 18.80703*21.4*9.806
= 3946.625 N
Buoyant force Fb= V*p hg*g
= 18.80703*13.6*9.806
= 2508.136 N
Apparent weight = Wr-Fb
= 3946.625-2508.136
= 1438.489 N
Therefore Apparent weight is 1438.489 N</span>
