    Finding the magnitude of the force and direction.

    Homework Statement A long wire carrying 6.50A of current makes two bends. The bent part of the wire passes through a uniform 0.280T magnetic field directed as shown in the figure and confined to a limited region of space. Part A: Find the magnitude of the force that the magnetic field...

    Household currents physics homework

    Homework Statement Typical household currents are on the order of a few amperes. If a 1.60A current flows through the leads of an electrical appliance, how many coulombs pass through it in 6.50min ? Homework Equations I=ΔQ/Δt The Attempt at a Solution 6.50min=1min/60s= 0.108s...

    What is the Total Momentum After Two People Push Each Other on Ice Skates?

    after reviewing it I realize that the total momentum would zero. Because of the fact that only the masses are given and there's no other way to compute this.

    Gravitational force and normal force.

    ok I didn't taught about the free body diagram thanks.

    Gravitational force and normal force.

    Homework Statement 1) A 0.25kg book rest on a table. A downward force of 9.5 N is exerted on the top of the book by a hand pushing down on the book. 2)what is the size of the normal force exerted by the table on the book Homework Equations F=ma The Attempt at a Solution 1)...

    What is the Total Momentum After Two People Push Each Other on Ice Skates?

    that the final momentum will be given with their respected velocities. 0+0=52kgv1(final)+77kgv2(final). But I still don't see a way to solve this. Unless I factor the v(final)?

    What is the Total Momentum After Two People Push Each Other on Ice Skates?

    well I can think of the conservation of momentum equation: m1v1(initial)+m2v2(initial)=m1v1(final)+m2v2(final) you think I can use this equation?

    What is the Total Momentum After Two People Push Each Other on Ice Skates?

    Homework Statement two persons on ice skates stand face to face and then push each other away. their masses are 52 kg and 77 kg. what is the total momentum after they have pushed off Homework Equations the equation that would be most useful here would be P=Pa+Pb the equation for total...

    What is the resulting frequency of the oscillation?

    ok got it, but what about the displacement? does it not play a role in the equation?

    What is the resulting period of the oscillation?

    Homework Statement A 0.16-kg mass is hanging from a spring with spring constant 14 N/m. Then the mass is displaced from the equilibrium by 2.9 cm and let go. Homework Equations the period is the time for a one full cycle so the equation would be T= 2∏sqrtm/k The Attempt at a...

    What is the resulting frequency of the oscillation?

    Homework Statement A 0.31-kg mass is hanging from a spring with spring constant 13 N/m. Then the mass is displaced from the equilibrium by 3.3 cm and let go. Homework Equations for frequencthy the equation would be 1/T The Attempt at a Solution to T I would use this equation...
