Do perpendicular wires have force? The wires are at right angles, so there is no force at the point of closest approach because the magnetic field from one wire is parallel to the other wire. Do perpendicular wires exert force on each other? Yes. Two wires repel each other when carrying current in opposite directions—the […]

What two conditions must be met for an object to be in equilibrium? For an object to remain in equilibrium, two conditions must be satisfied – both the net force and the net torque must be equal to zero. An example of an object in equilibrium is a rod that is free to rotate about […]

What is the fundamental physical quantity? In physics, there are seven fundamental physical quantities that are measured in base or physical fundamental units: length, mass, time, electric current temperature, amount of substance, and luminous intensity. All other units are made by mathematically combining the fundamental units. These are called derived units. What is the derived […]

How many HP is a 50 lb trolling motor? So every 746 watts is roughly equivalent to 1 horsepower. Using this formula the popular Newport Vessels NV-Series 55lb Thrust Trolling Motor is rated as 624 watts at the highest forward speed and so 624/746 = 0.84 and would be roughly equivalent to a 0.84 horsepower […]

How is atomic number related to mass number? The number of protons determines an element’s atomic number and is used to distinguish one element from another. Together, the number of protons and the number of neutrons determine an element’s mass number. Is atomic mass equal to mass number? Atomic mass is also known as atomic […]

Why is a monopole magnet still impossible to exist? A magnetic monopole does not exist. Just as the two faces of a current loop cannot be physically separated, magnetic North pole and the South pole can never be separated even on breaking a magnet to its atomic size. A magnetic field is produced by an […]

What colors can you mix to make silver? Mix 1 part blue with 1 part black, and add a small amount of white to create silver. Adjust as needed until you are satisfied with the results. How do you make silver work? Varak is made by placing the pure metal dust between parchment sheets, then […]

What is the function of output device? An output device is any piece of computer hardware equipment which converts information into human read able form. It can be text, graphics, tactile, audio, and video. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer graphic Output devices, Plotters, Speakers etc. Is […]

Where can oil leak from an engine? The vast majority of leaks are due to degraded engine gaskets, oil pan leaks, oil seals or bad connections. Crawl under the car and check the oil pan seals. While you’re there also check the oil pan drain plug. Next check the timing cover seal and the valve […]

How fast will a 1200 kg car be traveling with its momentum is 2400 kg/m s? What is the mass of an object with a momentum of 250 kgm/s and a velocity of 5 in/s? 3. How fast will a 1200 kg car be traveling when its momentum is 2400 kgm/s ? p=1400 tots! What […]
