Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model, 
Speed of the model, 
Mass of another model, 
Initial speed of another model, 
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :
V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
Answer:
Explanation:
Given
coefficient of kinetic friction
=0.34
inclination 
weight of block=51 N
(a) When block is moving upward friction force acts downward
thus
as block is moving with constant velocity thus 
is zero
(b)When Block slides down the wall friction changes its direction to oppose the block
Answer:
C
Explanation:
Gravitational forces are acting on a masses . It gives
F = (GmM)/ r2
F - force acting on two masses
G - Gravitational Constant
m, M - Mass
r - distance between two mass
Magnetic force acting on due to magnetic fields
Nuclear force is acting on due to nuclear reaction . This is happened inside th sun between H and He
Elastic force is acting due to stress and strain of the object
In comparison to their neutral parent atom, anions are bigger and cations are smaller.
<h3>Why are anions of the same element larger than their neutral counterparts?</h3>
They are forced to spread out more due to electron-electron attraction. They can get closer to each other because there is less electron-electron repulsion.
Because cations contain fewer electrons than their parent atoms while maintaining the same nuclear charge, they are always smaller than those atoms. The leftover electrons are therefore held by the protons in the nucleus more tightly, and as a result, their radii are less than those of the parent atoms. With anion, this is the exact opposite.
