Answer:
Weight is a force.
Explanation:
Force acting on an object is defined in terms of mass and its acceleration. Its mathematical force is given by
F = ma
Weight of an object is force that the Earth exerts on an object. It can be given by the formula as follows :
W = mg
g is acceleration due to gravity on the surface of earth
Hence, the correct option is (d).
Answer:
Pressure of woman will be 
Pressure of the elephant will be 
Explanation:
We have given that mass of the woman m = 80 kg
Acceleration due to gravity 
Diameter of shoes = 1 cm =0.01 m
So radius 
So area 
We know that force is given F = mg
So 
Now we know that pressure is given by 
Now mass of elephant m = 5500 kg
So force of elephant = 5500×9.8 = 53900 N
Diameter = 20 cm
So radius r = 10 cm
So area will be 
So pressure will be 
talk, make conversation. text isnt always the answer, but sadly now it is. text them or better yet, call them. you can talk and then do not just blurt it out. say it calmly. they say yes, congrats, but if they say no, do not have a mental breakdown. it might ruin a friendship.
Answer:
Option B. Coulomb Repulsion
Explanation:
The reason for the heavy nucleus not being able to follow the trend or the N= Z line is because of the fact that as the atomic number, Z of an atom increases, the number of protons inside the atom also increases. Since the neutrons are charge less particles whereas the protons are positively charged particle and hence as these increases in number there is an increase in the repulsive force between the like charges, i.e., positively charged protons which is Coulomb repulsion.
Answer:
When an electrical current passes through a wire, a magnetic field is generated around it. Likewise, if the magnetic field around a wire is changed ( for example by rotating a coil inside a stationary manger), electricity will move through the wire.
