Why do bats die near wind turbines? When a wind turbine’s blades move, they cause a drop in nearby air pressure. If a bat flies too close to a turbine, this drop in air pressure can damage its lungs. They found that each wind turbine kills around 5 birds and 12 bats every year! How […]

What is the charge on the 2uf capacitor? Answer. Answer :- No charge flows in 2uf capacitor at steady state. In steady state there is no charge which flows in capacitor. What is charge of 3 uF capacitor in steady state? In the circuit shown, the charge on the 3uF capacitor at steady state will […]

Was Rayon a real person? So the story being shopped as true is, at its heart, a fiction. The movie Woodruff is a hyper heterosexual and bigot, and his heroism stems both from creating the Dallas Buyers Club and being taught tolerance by Leto’s Rayon. And Rayon is an entirely fabricated person. Was Suicide Squad […]

What happens when you shine a red light on a blue object? So what happens if you shine only red light onto a blue object? All of that red light gets absorbed and the blue object will seem to be dark, almost black. If you now shine a blue light onto that blue object all […]

What is the SI unit of only current? ampere Can I use 110v in USA? It will be just fine, as long as your electricity is running to US spec. It really can be anywhere from 110V to 120V +/- 5%. Can I plug 120V into 110v? In the US, 110V isn’t a standard voltage. […]

When was the last partial lunar eclipse 2020? November 29–30, 2020 Penumbral Lunar Eclipse This is the last penumbral lunar eclipse of 2020. Can I see the lunar eclipse in 2020? The final lunar eclipse of 2020 will appear over North and South America, the Pacific Ocean and its neighboring regions on Nov. 29-30. This […]

Can plate tectonics be proven? What is the cause of plate tectonics? Although this has yet to be proven with certainty, most geologists and geophysicists agree that plate movement is caused by the convection (that is, heat transfer resulting from the movement of a heated fluid) of magma in Earth’s interior. What are the evidences […]

When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

Why do wheels have friction? A wheel or ball on a surface is held there by static sliding friction. In order to start the rolling motion, a force or torque must be applied to the wheel. The force of the static sliding friction prevents the wheel from sliding and thus initiates the rolling motion. Is […]

What is negative acceleration called? The other name of negative acceleration is Retardation or Deceleration. A deceleration is opposite to the acceleration. The deceleration means the decrease in the speed of body/object movement. What is negative acceleration in simple words? According to our principle, when an object is slowing down, the acceleration is in the […]
