Answer:
Explained.
Explanation:
Only the first question has been answered
In a period from left to right the nuclear charge increases and hence nucleus size is compressed. Thus, atomic radius decreases.
In transition elements, electrons in ns^2 orbital remain same which is the outer most orbital having 2 electrons and the electrons are added to (n-1) d orbital. So, outer orbital electron experience almost same nuclear attraction and thus size remains constant.
20 g = 20 / 1000 = 0.02 kg.
Magnitude of momentum of the sparrow = mass * velocity
= 0.02 * 8.1
= 0.162 kg-m/s. (answer)
Answer:
77 Ω
Explanation:
For resistors in parallel:
1/R = 1/R₁ + 1/R₂ + 1/R₃
1/26 = 1/68 + 1/93 + 1/R₃
1/R₃ = 0.013
R₃ = 77
The resistance of R₃ is 77 Ω.
OMG! That’s horrible. The answer is C though, inbreeding is when two genetically related organisms smash and create offspring. Often times it can result in genetic defects.
Answer:
impulse = force * time = 20 * 10 = 200 Ns
change in momentum = impulse = 200 kgm/s
