Because the atoms and molecules all have different properties
Answer:
126 mWb
Explanation:
Given that:
length (L) = 50 cm = 0.5 m, radius (r) = 5 cm = 0.05 m, current (I) = 10 A, number of turns (N) = 800 turns.
We assume that the magnetic field in the solenoid is constant.
The magnetic flux is given as:
Answer:
1. at least two charged interacting parts
2. from the electric fields of charged subatomic particles
3 an arrow released from the bow
4Electrical fields of charged particles interact, bonding those with opposite charges.
5 the interaction of the electric fields of protons and electrons
6 The energy stored in the system increases.
7 Kinetic energy increases because the magnets move in the direction of the field.
8 Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.
9
The energy stored in the field decreases because the magnet moves in the direction of the field.
10 The energy stored increases and then decreases.
11 The wire was not connected to the source.
12 The electromagnet will become more powerful.
the rest are written, hope this helps (:
Answer:
*The same balloon put into the freezer would be smaller and shriveled.
* The volume decreases as the temperature decreases.
* using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2
V2= 1.54 liters which proves when temperature decreases , volume decreases as well.
Explanation:
The volume increases as the temperature increases, and volume decreases as the temperature decreases.
using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2
Change Celsius to kelvin by adding 273.
2 liters/ 315 K = V2/243 K
Cross multiply and then divide by 315 to find V2
2 liters x 243 K / 315 K = V2
The Kelvin cancels itself out.
486 liters /315=V2
V2= 1.54 liters.
This proves that when the temperature decreases , so does the volume.
