How does a person move forward during swimming? A person applies force on the water in backward direction and water according to the third law of motion water apply an equal and opposite force in the forward direction which helps a person to swim. How do swimmers reduce drag? Here are ten good ways to […]
What is the charge on each plate of the capacitor?
What is the charge on each plate of the capacitor? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero. Can there […]
What are the 4 types of equilibrium?
What are the 4 types of equilibrium? There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples. Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of […]
What does Trappist-1 look like?
What does Trappist-1 look like? TRAPPIST-1, also designated 2MASS J23062928-0502285, is an ultra-cool red dwarf star with a radius slightly larger than the planet Jupiter, while having 84 times Jupiter’s mass. It is about 40 light-years (12 pc) from the Sun in the constellation Aquarius. Which Trappist planet has the lowest mass? TRAPPIST-1d is the […]
How do you kill a kangaroo rat?
How do you kill a kangaroo rat? Trapping with snap traps is probably the most efficient and humane method for kangaroo rats. Mouse traps will suffice for smaller animals, but Victor® “museum specials” or rat traps are needed for larger kangaroo rats, particularly the bannertail. Why do kangaroo rats not drink water? Because their habitats […]
How do you calculate the no load speed of a DC motor?
How do you calculate the no load speed of a DC motor? By multiplying the velocity constant by the nominal motor voltage, obtain the theoretical no-load speed of the motor (zero torque and no-load speed) and plot it on the left vertical axis. Draw a straight line between this point and the stall torque and […]
What are some interesting facts about the Alpine biome?
What are some interesting facts about the Alpine biome? It is cold, snowy and windy. It is usually below freezing at night. Alpine biomes are located on mountains. They are below the snow line…. Quick Facts Location on mountains; above 10,000 feet Area of coverage 16% of earth’s surface 31,510,000 square miles (81,610,000 square kilometers) […]
Why is current constant in a parallel circuit?
Why is current constant in a parallel circuit? Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit). Parallel resistors do not each get the total current; they divide it (current is dependent on the value of each resistor and the number of total […]
How do you make a simple electromagnet?
How do you make a simple electromagnet? Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil. […]
What do you mean by hydraulic?
What do you mean by hydraulic? Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Where are hydraulic […]
