What are 5 facts about electromagnets?

Electromagnets are created by passing an electric current through a coil of wire. They can be turned on and off by controlling the flow of electricity. The strength of an electromagnet can be increased by adding more coils of wire or increasing the current. Electromagnets are used in a wide range of devices, from speakers and electric motors to MRI machines. The polarity of an electromagnet can be reversed by changing the direction of the electric current.


Suppose a rock in free fall is dropped off a cliff after falling 5 seconds it speed will be 100?

The speed of the rock after 5 seconds of free fall would not be 100. The speed of an object in free fall increases by 9.8 m/s every second. After 5 seconds, the speed of the rock would be 49 m/s (approximately), assuming no air resistance.


An electromagnet has 20 coils around a wood stick and can pick up 5 paper clips Describe how you could modify the electromagnets to pick up more paper clips?

1. You could change the wood stick to an iron rod. 2. You can increase the number of coils. 3. You could increase the power (wattage) through the coil. 3 ways you can modify the electro-magnet to pick up more paper clips, probably more available.


Why do two objects of different weight and dropped from the same height hit the ground at the same time?

Why do you ask. Do you think they should not hit the ground at the same time. Do you think perhaps a heavier object should fall faster. Let's check it out. Take a 1-pound stone and a 5-pound stone. We're pretty sure that the 5-pounder is going to fall faster than the 1-pounder does, but let's try it out anyway. Take both of your stones to the top of the leaning tower, but don't drop them yet. Before you drop anything, tie your stones to the ends of a 6-foot string, then drop them together. The 5-pounder wants to fall faster, so it hurries the 1-pounder ahead a little. The 1 pounder wants to fall slower, so it holds the 5-pounder back a little. Together they fall a little faster than the 1-pounder wants to, but a little slower than the 5-pounder wants to. Right ? So when they fall together, they fall slower than a single 6-pound stone would fall. We're sure you must be OK with that.


What is the weight load ratio of fall arrest harness?

The weight load ratio of a fall arrest harness is typically around 5:1, which means it can support a load up to five times the maximum user weight. This ratio is designed to provide a safety margin in case of a fall. It is important to choose a harness that is rated for your specific weight and intended use.

Why do all given dates which fall on Friday always fall on a Wednesday four years later?

Within any 4 year period, there is always a leap year. That causes a day to be skipped. So after 4 years, a date will be on a day 5 days after the one it was on 4 years before that. Wednesday is 5 days after Friday, so if a date is on a Friday, 4 years later it will be on a Wednesday.
