Answer:

I cant understand the question well but i will tell u how to solve it

first apply f = ma eqaulation vertically...then u will get an r = mg which means normal upward force = weight of the object (to find weight multiply mass by 9.81)

f = ma \\ r  - mg = 0 \\ r = mg

after that use friction eqaution which is

f =  \mu \times r

(mu) is the coefficient of friction and (r) is the vertical normal force then by substituting value you can get an answer for the friction

the use

f = ma \\ f \cos(37)  - fr = ma

by using the above eqaution you can get an answer for acceleration...

hope you can understand...

Answer:

Explanation:

I hate these kinds of problems,  luckily I can't understand how much the kinetic friction is for this ,  the words are all mixed around.  and don't read well.  Maybe this went through a translator program?   My suggestion draw the free body diagram.   so you can see where the forces are, and how they are acting.   getting the free body diagram right.. usually makes these problems pretty straight forward.   just do the steps and you get the answer.

A magnetic field of magnitude 0.550 T is directed parallel to the plane of a circular loop of radius 43.0 cm. A current of 5.80
Assoli18 [71]

Answer:

\mu = 3.36\times 10^{-3}\ A-m^2

Explanation:

Given that,

The magnitude of magnetic field, B = 0.55 T

The radus of the loop, r = 43 cm = 0.43 m

The current in the loop, I = 5.8 mA = 0.0058 A

We need to find the magnetic moment of the loop. It is given by the relation as follows :

\mu = AI\\\\\mu=\pi r^2\times I

Put all the values,

\mu=\pi \times (0.43)^2\times 0.0058\\\\=3.36\times 10^{-3}\ A-m^2

So, the magnetic moment of the loop is equal to3.36\times 10^{-3}\ A-m^2.

How would you go about measuring the speed of a vehicle? What measurements would you have to take? What calculations would you h
White raven [17]

Answer:

For a body moving at a uniform velocity you can calculate the speed by dividing the distance traveled by the amount of time it took, for example one mile in 1/2 hour would give you 2 miles per hour. If the velocity is non-uniform all you can say is what the average speed is.

What perspective of dream interpretation is being offered?
vitfil [10]

Psychoanalytic dream interpretation is a subdivision of dream interpretation as well as a subdivision of psychoanalysis pioneered by Sigmund Freud in the early twentieth century. Psychoanalytic dream interpretation is the process of explaining the meaning of the way the unconscious thoughts and emotions are processed in the mind during sleep.

There have been multiple methods used in psychoanalytic dream interpretation, including Freud's method of dream interpretation, the symbolic method, and the decoding method. The Freudian method is the most prominently used in psychoanalysis and has been for the last century. Psychoanalytic dream interpretation is used mainly for therapeutic purposes in a variety of settings. Although these theories are used, none have been solidly proven and much has been left open to debate among researchers. Some studies have shown that areas of dream interpretation can be invalid and therefore a decline in importance has been seen in psychoanalytic dream interpretation.
