Answer:
The answer is 0.00005 meters
Explanation:
In order to determine the diameter in meters, you have to know the meaning of the unit [um]. This unit is called "micrometer" and its value is m.
Then, we change the [um] unit into its expanding form:
50 um=
Finally, the diameter in meters is 0.00005 meters.
Answer:1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. ... With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet [whether this comes from another permanent magnet, or a solenoid].
Explanation:Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.To restore a permanent magnet, you need to cool the metal (if heated) and expose it to a magnetic field. Coil your copper wire tightly around the piece of metal you would like to restore as a permanent magnet.
Answer:
#include <iostream>
#include <vector>
using namespace std;
int main() {
const int NUM_GUESSES = 3;
vector<int> userGuesses(NUM_GUESSES);
int i = 0;
int uGuess = 0;
for(i = 0; i <= userGuesses.size() - 1; i++){
cin >> uGuess;
userGuesses.at(i) = uGuess;
}
cout << endl;
return 0;
}
Explanation:
First inbuilt library were imported. Then inside the main( ) function, 3 was assigned to NUM_GUESSES meaning the user is to guess 3 numbers. Next, a vector was defined with a size of NUM_GUESSES.
Then a for-loop is use to receive user guess via cin and each guess is assigned to the vector.
The acceleration of gravity is 9.8 m/s². That means that the speed of the marble is always 9.8 m/s greater downward than it was 1 second earlier.
You want to know when the marble is going to stop climbing. Well, that
will be when its upward velocity has dwindled to zero. That in turn is the
time when its upward velocity is 1.3 m/s less than it was when you tossed it.
(1.3 m/s) / (9.8 m/s²) = 0.133 second (rounded)
Friction stole the book's kinetic energy, and turned it into heat energy ... which blew away in the breeze.
