ummmm it might be 300... i used a calculator
sorry if it is wrong
<h2>Answer:</h2>
<u>By wrapping the wire along a solenoid and connecting it to electricity</u>
<h2>Explanation:</h2>
If you wrap a copper wire into coils and run an electrical current through it, you will create a magnetic field. If you rotate a permanent magnet as opposed to an item that has been magnetized inside a coil of copper wire, you can create an electrical current. The strength of magnetic field generated is proportional to the amount of current through the winding.
Solid has vibrating molecules that barely move to keep it's shape
liquid moves at an average speed and keeps it's volume but not it's shape
gases move quickly and all over the place so they don't have a shape or volume
plasma is the quickest moving and is like a gas
Answer:
7.39 m/s
Explanation:
Applying
K.E = 1/2mv²..................... Equation 1
Where K.E = Kinetic Energy, m = mass of the ball, v = velocity of the ball.
Make v the subject of the equation
v = √(2K.E/m)................. Euqation 2
From the question,
Given: K.E = 30 J, m = 1.1kg
Substitute these values into equation 2
v = √(2×30/1.1)
v = √54.54
v = 7.39 m/s
Given:
Velocity: 0.5 mile/minute
Time: 12 minute
Now we know that speed and velocity have the same magnitude. Hence speed=velocity=0.5 mile/min
Substituting the given values in the above formula we get
Distance = 0.5 x 12= 6 miles
