How much work is done by the force F on the two-block system?
The work done by the force F on the two-block system is equal to the force multiplied by the distance the force moves the system.
What is the Difference between resultant and equilibrant?
Resultant force is a system of forces in the single force equivalent to the system, whilst equilibrant force is a force capable of balancing another force to achieve equilibrium.
What are fundamental condition for resonence?
For resonance to occur, two main conditions must be met: 1) The frequency of the driving force must match the natural frequency of the system, and 2) There must be minimal damping in the system to allow the energy to build up and sustain the oscillations.
Explain why a single force cannot exist?
A single force cannot exist because forces are interactions between two or more objects. For a force to be present, there must be an object or system exerting the force and another object or system experiencing the force. It is this interaction that defines and characterizes a force.
How much force would be needed to lift a 200-pound object with a double pulley?
To lift a 200-pound object using a double pulley system, the force needed would need to be equivalent to half the weight of the object. This is because a double pulley system reduces the amount of force required by distributing it evenly between the two strands of the rope. Therefore, the force needed would be 100 pounds.
What is the two organs for muscular system?
The two main organs of the muscular system are muscles and tendons. Muscles are responsible for generating force and movement, while tendons connect muscles to bones and enable the transfer of that force to produce movement.
What were the major fighting events on the kokoda track?
The 7th Australian Division, and a Japanese force equivalent to two regiments.
What are two ways the nervous system can control the force generated by a muscle?
The two ways that the nervous system can control the force generated by a muscle are by increasing amount and size of contactable muscle units and increasing how often action potentials are sent from the brain to the muscle.
Why electrostatic force between two charges is called central force?
The electrostatic force between two charges is called a central force because it acts along the line joining the two charges, targeting the center of the system formed by the charges. This means that the force is radial in nature, pointing towards or away from the central point between the charges.
When measuring torque is a two foot-pound measurement the equivalent of two pounds of force applied one foot from the pivot point or one pound of force two feet from the pivot point?
The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
How much force is used to move 100pds on a 2 pulley system?
In a 2-pulley system, the force required to move a 100-pound object would be halved. Therefore, the force needed would be 50 pounds. This is because the weight is distributed between the two sides of the pulley system, reducing the amount of force required to move the object.
How strong is nuclear force?
The force between two nucleons depends on the distance. According to the Wikipedia article, the maximum attractive force, at a distance of about 1 fm (femtometer), is in the order of 25,000 newton. This force is equivalent to the weight of a 2.5-tonne mass.
