227kj Because The first thing to do here is to calculate the energy of a single photon of wavelength equal to
527 nm
, then use Avogadro's number to scale this up to the energy of a mole of such photons.
Answer:C
Explanation: This is because the time for the 26 gram ball was around 6 seconds longer which if they were dropped at the same height then the ball with more mass would fall faster because of its gravitational pull.
Answer:
a) 120 N
b) 5 N
c) 0.2 N
d) Mass remains the same, and weight decreases.
Explanation:
<em>Use the formula W = mg, where mass is in kg, and gravitational field strength in N/kg.</em>
a)
W = mg
= 12 × 10
= <u>120 N</u>
b)
500 g = 0.5 kg
W = mg
= 0.5 × 10
= <u>5 N</u>
c)
20 g = 0.02 kg
W = mg
= 0.02 × 10
= <u>0.2 N</u>
d)
<u>Mass remains the same, and weight decreases.</u>
Answer:
If the older generation is lacking, the younger generation would likely have knowledge, skill, or a positive attitude in some combination, but it is relative to the culture.
The simple reason is the desirability for genetic variation using recessive genes.
In other words, if the older generation lacks something, it tends to be something they don’t need, but something that will look good on young people. But mostly relative to the culture and education system.
Hope this helps
