Answer:
R = 0.1 ohms
Explanation:
It is given that,
Voltage of the battery, V = 12.5 V
Current flowing in the car's starter, I = 125 A
We need to find the effective resistance of a car's starter. It can be calculated using Ohm's law. Let R is the resistance.
So, the resistance of the car's starter is 0.1 ohms.
Answer:
A: Copper is a good conductor
Explanation:
For an electrical current to flow through something, the main power source has to fight against the resistivity. Copper wire has a very low level of resistivity making it an excellent conductor. Basically, copper is super bendy and flexible, electricity.
Fun fact, sinc humans are also super bendy and essentially big sacs of all things wet and watery, we're considered to also be excellent conductors. We also have very intricate circuitry and a lot of natural electricity so basically, we were made for it, especially since the body already used little bits of electricity to function.
Answer:
Anaerobic
Explanation:
aerobic: <em>relating to, involving, or requiring free oxygen.</em>
anaerobic: <em>relating to, involving, or requiring an absence of free oxygen.</em>

Time= v*sintheta/g = 10*1/9.8= 1.02s therefore h=1/2*9.8*(1.02)^2= 5.10m
Answer:
Answer: 18.3 km/s
Explanation:
If a satellite in Molniya orbit has an apogee at 48.000 km as measured from the center of Earth, and a velocity of 3.7 km/s. Its velocity in at perigee would be 18.3 km/s.
