If you take the wheel as your system, would the tension in the red rope be 10 lbs also? pic attached thanks

I would really like someone to answer this simple question. I have searched the net and i cannot find the answer, i know i have only just read it but i can't remember where. Basically all i want to know is the name of the movement of a while when it is moving a vehicle (i don't mean around...

Hi, first of all I'd like to say hello as I'm new to this forum. Here are my questions: If a single atom would be held in an empty room (vacuum/no gravity) would it move or would it stand still? If it does move what would the movement would look like? The same question goes for...

I have a structure that looks something like this; a steel-pole is vertical for 2m and then horizontal for 1m, like an uppside-down L-shape. At the end of the horizontal part, a force acts downwards (10kN). How do I go about to find both the horizontal and vertical movement of the point where...

According to the theory of relativity and according to observations, adding movement to mass makes it more massive. All the components of mass are in a jumble of related motion. Protons, neutrons, electrons, atoms, and molecules comprise mass; they all vibrate and orbit and whiz around inside...

Hey guys, please help. Two people, one of mass 65kg and the other of mass 40kg, sit in a rowboat of mass 85kg. With the boat initially at rest, the two people, who have been sitting at opposite ends of the boat, 4.0m apart from each other, exchange seats. How far will the boat move? and in...

A particle that moves a certain distance in the gravitational field of a small mass,changes its weight as it moves.But if that particle had been stationary relative to the small mass, and the gravitational field had changed its strength with time, in such a way that the weight of the...

Here is another one of these spool problems: A large spool of rope stands on the ground with the end of the rope lying on the top edge of the spool. A person grabs the end of the rope and walks a distance L, holding onto it. The spool rolls behind the person without slipping. (a) What length of...

I am a completely ignorant to Physics in general so bear with me. I was reading something recently and the author stated "an electron can jump instantaneously from one atom orbital to another without moving across the space between them" Is this true? Is it taken completely out of context or...

Our Earth spins on its axis at 1600 km/hr, and then travels around the sun at some higher speed (i don't remember what) and then our galaxy spins on an axis at a higher speed, and it in turn revolves around some Great Attractor at the speed of c. So IOW are we traveling at a net speed of c...

Hi all, I have a question on the movement of a point on a sphere. Consider a point P(\theta,\phi) (\theta and\phi are the latitude and the longitude, respectively)moving from a point P_1(\theta_1,\phi_1) to a point P_2(\theta_2,\phi_2) with a constant speed v. How to find the latitude...

can anyone help me with this question from my homework? i have the system in the picture and i need to find out the type of movement of the bar. the box named A is an inductor, the 2 long parallel lines are infinite conductors. there's a magnetic field into the page. the black bolded line is a...

Can anyone help me with this problem please.. I included the picture of the problem below.. m = 0.4 Kg

Hi can anyone help me with this problem.. Picture is included.. I am kinda lost.. thank you so much m = 0.4Kg

I was recently studying quantum mechanics and thought of a situation quantem mechanics in a way is movement and how movemnt and reality go together such as e=mc squared but is it posible that the energy of movement or the velocity if you wish could be altered by another energy causing the...

Hi, When a pendulum is swung and it reaches a point of reverse direction, there is a moment in time and space that the pendulum and the observer is effected by. A point where a given movement either starts, reverses or is changed. This point in time and space I call a "Teeter point" ...

I have read that mass can be measured by the degree of movement resistance to surrounding activity, so that an object high in mass will take more energy exertion to move than an object with a relatively lower mass measurement. Does anyone else have a different working definition for the word...
