How do you calculate the voltage after a resistor? Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor […]

How fast can you go in a neighborhood? The speed limit in the residential or business areas is 25 mph unless otherwise posted. A safety zone is an area of the road where street cars or trolleys are sharing the road with you. What speed do you go if there is no sign? They are […]

Which location most likely has the warmest climate? The area near the equator will be the warmest climate region as the sunlight comes directly to this region. Option B. The area 60° south of the equator will be the region near the tropic of Capricorn, where the temperature will be less. Why is East Coast […]

When a force is applied on a body it may change its? A force applied on an object can change its state of rest or motion and its shape or size. What are the three laws of motion class 9? In the first law, we come to understand that an object will not change its […]

What colors are the parents shown in Punnett Square B? What color are the parents shown in the punnet square B? The white guinea pig is homozygous (bb) and the black guinea pig is heterozygous (Bb). If the black guinea pig parent were a homozygous (BB) then there would be no chance for the offspring […]

What is P-type semiconductor with example? A p-type semiconductor is a type of semiconductor. When the trivalent impurity is added to an intrinsic or pure semiconductor (silicon or germanium), it is said to be a p-type semiconductor. Trivalent impurities such as boron (B), gallium (Ga), indium (In), aluminium (Al) etc. are called acceptor impurity. Is […]

Is there a ball that can bounce forever? The law of conservation of energy implies that a bouncing ball will bounce forever. Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor. What are bouncy […]

How do you make a dead lithium battery work again? Full Recharge You’ll need to completely drain the battery for this to work, so once it reaches zero percent, keep turning it back on until it doesn’t even have enough power to boot. Now, plug in the power cord (to a power outlet) and let […]

What are the embryological evidence that we all have a common ancestry? They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos. What is the evidence of embryology? The study of one type of evidence of evolution […]

When electric field is applied on the ends of a conductor the free electrons start moving in direction? These free electrons inside the conductor move randomly and frequently collide with heavier atoms and change their direction of motion every time. When a steady electric field is applied to the conductor, the electrons start moving towards […]
