The frictional force is 218.6 N
Explanation:
The block in the problem is at rest along the inclined surface: this means that the net force acting along the direction parallel to the incline must be zero.
There are two forces acting along this direction:
- The component of the weight parallel to the incline, downward along the plane, of magnitude

where
m = 46 kg is the mass
is the acceleration of gravity
is the angle of the incline
- The (static) frictional force, acting upward, of magnitude 
Since the block is in equilibrium, we can write

And substituting, we find the force of friction:

Answer: 0.16
Explanation:
Newton's second law states that the resultant of the forces exerted on the bookcase is equal to the product between the mass (m) and the acceleration (a):

where
F = 58 N is the force applied
Ff is the frictional force
Substituting, we find the frictional force

The frictional force has the form:

where
is the coefficient of kinetic friction. Re-arranging the formula, we can find the coefficient:

If you were somehow magically transported to Jupiter, your mass
would not change, but your weight would become roughly 2.5 times
your Earth weight.
Answer:
The __law__ conservation
of state that either energy may produced nor destroyed
Answer : 
Explanation :
Given that,
Charge of particle 1 = 
Distance x = 6 cm
Charge of particle 2 = 
Distance x = 27 cm
Total distance = 

Particle 1 is at (6,0) and particle 2 is at (27,0) .
Therefore, midway (16.5, 0)
Now, 
Formula of electric field

Now, the the electric field due to particle 1



Similarly, the electric field due to particle 2

Resultant Electric field


Hence, this is the required answer.
