Answer:
0.00225 N/m
Explanation:
Parameters given:
Current in first wire, I(1) = 15A
Current in second wire, I(2) = 15A
Distance between two wires, R = 1cm = 0.01m
The force per unit length between two current carrying wires is:
F/L = μ₀I(1)I(2)/2πR
μ₀ = 4π * 10^(-7) Tm/A
F/L = [4π * 10^(-7) * 15 * 15] / (2π * 0.01)
F/L = 2.25 * 10^(-3) N/m or 0.00225 * 10^(-3) N/m
Answer:
Blood is thicker than water due primarily to the presence of red blood cells
Answer: <u>This is because it becomes more dense when cells are added</u>
Hope this helped :3
Any unit of acceleration must have the dimensions (form) of
(a unit of length) / (a unit of time)²
Answer:
Beta minus decay
Explanation:
Beta decay is due to a weak nuclear interaction, it takes place in the atomic nucleus and occurs when a neutron is converted to a proton, or a proton into a neutron. When a neutron is converted to a proton an electron and an electronic antineutrino are emitted from the nucleus, this is called beta minus decay.
Electrons move from the sweater to the balloon. The sweater becomes positively charged, while the balloon becomes negatively charged.
Explanation:
- Sweater is a conductive material, which means it readily gives away its electrons.
- Consequently, when you rub a balloon on Sweater, this causes the electrons to move from the Sweater to the balloon's surface.
- The rubbed part of the balloon now acquired a negative charge. Objects made of rubber, such as the balloon, are basically electrical insulators, meaning that they resist electric charges flowing through them.
- This is why only part of the balloon may have a negative charge (where the wool rubbed it) and the rest may remain neutral after electrostatic process.
