Should I charge my new phone overnight?
Should I charge my new phone overnight? “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.” The official word is to keep your phone charged – […]
What is electric field and its SI unit?
What is electric field and its SI unit? Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces (or interactions) of nature. The derived SI units for the electric field are volts per meter (V/m), exactly equivalent to newtons per coulomb (N/C). What is SI unit of […]
Which direction does a freely suspended magnet point to?
Which direction does a freely suspended magnet point to? A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction. Why does a freely suspended magnet? A freely […]
Is bamboo stronger than oak?
Is bamboo stronger than oak? In general, bamboo falls at about 1,200 to 1,400 on the Janka Hardness Scale, which means it’s a little harder than oak and ash. Some manufacturers claim the product is 12 percent harder than North American maple, but that’s hard to say. What is the strongest wood on earth? lignum […]
What is true for living organism?
What is true for living organism? All living things are made of cells, use energy, respond to stimuli, grow and reproduce, and maintain homeostasis. All living things consist of one or more cells. All life processes require energy, so all living things need energy. All living things can sense and respond to stimuli in their […]
What is the relationship between buoyancy and volume?
What is the relationship between buoyancy and volume? Compressible objects As a floating object rises or falls, the forces external to it change and, as all objects are compressible to some extent or another, so does the object’s volume. Buoyancy depends on volume and so an object’s buoyancy reduces if it is compressed and increases […]
When would you use cumulative frequency?
When would you use cumulative frequency? Cumulative frequency is used to determine the number of observations that lie above (or below) a particular value in a data set. The last value will always be equal to the total for all observations, since all frequencies will already have been added to the previous total. What is […]
What would happen if there was no convection current in the mantle?
What would happen if there was no convection current in the mantle? If Earth had no convective currents, that would mean the inner Earth has solidified, therefore, we would not have plate tectonics. Our Earth’s crust is made up of plates of varying sizes that move very slowly around the planet over time, this theory […]
Is beating of drum periodic motion?
Is beating of drum periodic motion? The beating of the drum occurs at defined period. So, it is a periodic motion. Which is periodic wind? Periodic winds blow at regular intervals or in regular cycles. They are winds that result from localised differences in pressure and temperature. For example, land and sea breezes and the […]
