36.0 Ω
19.6 Ω
18.3 Ω
25.9 Ω
Answer:
Total resistance is 19.6 Ω for the circuit .
Explanation:
Given:
Six resistors of a circuit namely to .
Where
and are in series.
and are in parallel.
and are in parallel.
We know that continuous resistor which are in series are added up to find the equivalent resistance.
Similarly resistors which are arranged in parallel their equivalent resistance is for the case of and .
According to the question:
Total resistance = R(equivalent) :
⇒
⇒
⇒
⇒
⇒ Ω
So the total resistance of the circuit depicted is 19.58 Ω approximated to nearest tenth that is 19.6 Ω
Answer: Momentum = (mass) x (speed)
Divide each side by (speed): Mass = (momentum) / speed
Mass = (45,000 kg-m/s) / (30 m/s) =
1,500 kg .
Explanation:
Answer: C
Scientists observe the layers for evidence of similar rock types and fossil formations to determine the age of landforms. If they find the same fossil in two different locations, scientists may conclude that those fossils are most likely from the same time period. The same is true for landforms made of certain types of rock. When scientists see layers of similar rock sediments, they use that as evidence to support that are from a similar time period. By analyzing the rock layers, scientists estimate that Earth is 4.6 billion years old.
