When all the devices are connected using series connections, the circuit is referred to as a series circuit
Answer:
A.) it can show changes that occur in many different parts of earth at the same time
D.) it can be used to show how the parts of the cycle relate to one another
Explanation:
When a scientific diagram is used as a model, it explains the phenomena described in the research.
Scientific models describing water cycle help students understand that a group of parts which relate can combine to form a larger system. The different parts of a water cycle such as evaporation and condensation all work together to facilitate continuity of the water cycle. Additionally, the models highlights the individual processes contributed by the stages of water cycle showing changes and resulting processes.
Option B and C are incorrect because the model diagrams show much details including individual processes contributed by each of the parts leading to functioning of the whole water cycle process.
Answer: a. 667N
b. 665N
c. 54.5N
Explanation:
a) on the surface of the earth
W = mg
W = 68 × 9.81
= 667N
b) at the top of Everest (8848 m above sea level).
W =mg × R²/(R + H)²
W = 667 × [6378²/(6378 + 8.848)²
W = 665N
c) has 2 1/2 times the radius of the earth
W = mg × R²/(R + H)²
W = 667 × R²/(R + 2.5R)²
W = 54.5N
The total work done on the car is 784Joule.
<h3>What's the acceleration of the car?</h3>
- As per Newton's equation of motion, V= U+at
- U= initial velocity= 0 m/s
V= vinal velocity= 20m/s
t= time = 10s
a= acceleration
=> a= 20/10= 2m/s²
<h3>What's the distance covered by the car in 10 seconds?</h3>
- As per Newton's equation of motion,
V²-U² = 2aS
- S= distance covered by the car
- So, 20²-0=2×2×S=4S
=> 400= 4S
=> S= 400/4= 100m
<h3>What's the work done on the car due to frictional force?</h3>
Work done by frictional force= frictional force × distance
= (0.2×4×9.8)×100
= 784Joule
Thus, we can conclude that the work done on the car is 784Joule.
