Answer:
b. Gravity is the weaker force; it is related to mass.
Explanation:
Gravity is the force of gravitational attraction of earth on all objects near its surface
This force on all objects depends on the mass of the objects
This force is given by
so here it is a weak force as it depends on mass and acceleration due to gravity while strong nuclear force is independent of mass and it only depends on the distance between the nuclei.
So as we will change the distance between the nuclei the force between them will change
So here correct answer is
b. Gravity is the weaker force; it is related to mass.
The direction of the magnetic force is to the right.
<h3>What is the magnetic field?</h3>
The magnetic field is the region in space where the influence of the magnet is felt. The magnetic force is always in the direction of the magnetic field.
We can see from the image, that the direction of the magnetic force is to the right.

Explanation:
Answer:We are usually not aware of the electric force acting between two everyday objects because most everyday objects have as many plus charges as minus charges. Option A
Explanation:An electric force is exerted between any two charged objects( either positive or negative). Objects with the same charge will repel each other, and objects with opposite charge will attract each other. The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. Electric charges are generated all around us due to different surfaces bearing different types of charges. We are usually not aware of it because the quantity of positive charges equals the number of negative charges.
Answer:
life (N) of the specimen is 117000 cycles
Explanation:
given data
ultimate strength Su = 120 kpsi
stress amplitude σa = 70 kpsi
solution
we first calculate the endurance limit of specimen Se i.e
Se = 0.5× Su .............1
Se = 0.5 × 120
Se = 60 kpsi
and we know strength of friction f = 0.82
and we take endurance limit Se is = 60 kpsi
so here coefficient value (a) will be
a = 
......................1
put here value and we get
a = 
a = 161.4 kpsi
so coefficient value (b) will be
b = 
b = 
b = −0.0716
so here number of cycle N will be
N = 
put here value and we get
N = 
N = 117000
so life (N) of the specimen is 117000 cycles
