Answer:
True there is the permanent magnet and the electromagnet.
The gold will heat up almost twice as fast. The specific heat of a metal tells us just how much calories is needed to change the temperature of a metal by 1 degree celsius. Given this, the smaller the specific heat of a metal, the faster it will heat up.
Answer:
Basic kinematics, negating drag and assuming ideal conditions, we use the equation:
d=vi*t+1/2*a*t^2
Since vi is 0 (we know this because you’re dropping it, not throwing it)…
…and the only acceleration acting on it is gravity, a=9.8 m/s^2…
…we get
d=1/2(9.8)(5)^2
Explanation:
Some quick mental math tells us that this is about 125 m.
Plugging it in, we find it to be 122.5 m.
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
Answer:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
