<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
Answer:Explanation: According to Newton's third law, the force exerted by the bat hitting the ball will be equal in magnitude but opposite in direction of the force the ball exerts on the bat. Generally, your arms are stiff when you hit the ball forward, so you will not feel the bat "recoiling".

Answer:
34 m/s
Explanation:
The law of conservation of linear momentum dictates that the sum of initial and final momentum should be equal. Momentum is a product of mass and velocity.
Since the canon recoils, its recoil velocity is opposite hence
MV=nu where M and n are mass of cannon and cannoball respectively, v and u are the velocities of cannon and cannon balls respectively.
Substituting 200 kg for M and 1.7 m/s for v then 10 kg for n
200*1.7=10u
U=200*1.7/10=34 m/s
Answer:
the googles are 4.33mm from the edge
Explanation:
In this question, we are asked to calculate the distance of a set of googles from the edge of a pool.
We proceed as follows;
depth of pool , d = 3.1mm
Now, let i be the angle of incidence
i = arctan(1.8/1.2)
i = 56.31 degree
Using snell's law ,
n1 * sin(i) = n2 * sin(r)
1 * sin(56.3) = 1.33 * sin(r)
r = 38.72 degrees
Now,
distance of googles = 1.8+ d*tan(r)
distance of googles = 1.8+ 3.1 * tan(38.72)
distance of googles = 4.3 mm
