    How Long Does It Take a Ball to Hit the Ground If Thrown Downward?

    The constant term.Which means the term not having the variable t in it.

    How Long Does It Take a Ball to Hit the Ground If Thrown Downward?

    In your solution,you took square root of both sides which is incorrect.Instead,solve the quadratic equation formed in t.You will get the time taken.

    Undergrad Why Are Neutron-Neutron Interactions Essential for Nuclear Stability?

    I was recently taught the concept of nuclear forces in school.According to what was taught,nuclear forces were introduced to explain the stability of the nucleus.So,my question is that,can't we say that the nucleus is stable only due to neutron-proton and proton-proton interactions?Why are...

    Solving a DC Current Magnetic Flux Problem

    Okay so,the cross sectional area through which flux is to be found is shaped like a cylinder cut into half through the axis. Now,if I look at the curved area,the magnetic field lines will be in the shape of concentric circles and they will not cut this curved surface area at all(Hence,flux...

    Solving a DC Current Magnetic Flux Problem

    Homework Statement A direct current i=10 A flows in a long straight round conductor.Find the magnetic flux through half of the wire's cross section per one metre of it's length. Homework EquationsThe Attempt at a Solution I have spent quite a while thinking on this problem but I can't think of...

    Moments of a Ladder Propped Up Against A Wall

    You're right,C can be an option if moments are taken about the topmost point of ladder. About the pivot,I'm not sure what you mean. The force should be split into components and we should then take the component which is perpendicular to the distance.But,in this situation,the forces and the...

    High School Electromagnetic nature of light

    I was recently taught in school about the propagation of light as a combination of changing electric and magnetic fields. I had read somewhere that a magnetic field was basically an electric field in a moving frame of reference. So,I wanted to know if in some frame the propagation of light could...

    Electrostatics: Find relative permitivitty

    The question mentions that the electric field is reduced BY 1/3 and not to 1/3 as you have assumed.The rest of it seems right.
