Answer:

vₓ = 0.566 m / s,   W_total = 9.1 J

Explanation:

This exercise is a parabolic type movement, for the x axis where there is no acceleration

         x = v t

         vₓ = x / t

         vₓ = 0.34 / 0.6

         vₓ = 0.566 m / s

the work done is

X axis

In this axis there is no acceleration, therefore the sum of the forces is zero and since the work is the force times the distance, we conclude that the lock in this axis is zero.

        W₁ = 0

Y axis  

in this axis the force that exists is the force of gravity, that is, the weight of the body

         W₂ = Fy y

         W₂ = mg and

          W₂ = m 9.8 0.70

          W₂ = m 9.1

the work is a scalar for which we have to add the quantities obtained

          W_total = W₁ + W₂

          W_total = 0 + 9.1 m

           W_total = 9.1 m

In order to complete the calculation, the mass of the body is needed if we assume that the mass is m = 1

           W_total = 9.1 J

Generate description of the right hand rule for finding the magnetic field around a current carrying wire an tell how it is used
vladimir1956 [14]

Answer:

Right hand thumb rule : It is a rule used to find the magnetic field direction around current carrying wire .

Explanation:

It states that : "If you grasp conductor in your right hand such that thumb points in upward direction ,then the direction in which our finger curls gives the direction of magnetic field or magnetic lines of forces" .

This rule proves that :Current can give rise to magnetism .

Around every current carrying conductor there exist a magnetic field which can be easily felt .

According to this rule : When a current flows in upward direction ,the finger curls in anticlockwise direction and when direction of current reverses ,then the direction of field also reverses .
