Answer:
(4) 
more protons than electrons
Explanation:
Total positive change on the object is given as
now by the law of quantization of charge we know that the charge on any body is always in form of integral multiple of charge of an electron.
So we will have
here we know that
Now we know that the object is positively charged so here electrons must be less in numbers than protons
so correct answer will be
(4) more protons than electrons
B. The Particles Have Less Kinetic Energy than those of..
The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface.
Answer:
The dog has more momentum than the pony.
Explanation:
To solve this problem, we must remember the formula for calculating momentum, which is given below:
momentum = p = m*v
where m represents the mass of the object and v represents the velocity of the object
Using this knowledge, let's calculate the momentum for the dog and the pony.
Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s
Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s
Since 82 > 75, we can conclude that the dog has more momentum.
Hope this helps!
