Answer:
The speed of a turtle is 4m/s
Explanation:
speed = distance/time
distance = 100m
time = 25s
s = 100/25
= 4m/s
Answer:
N₂/N₁ = 45
Explanation:
The relation of the number of turns with the voltage is given by the EMF equation of transformer:
(1)
<em>where V₁: voltage of the primary winding, V₂: voltage of the secondary winding, N₁: number of turns in the primary winding, and N₂: number of turns in the secondary winding </em>
Assuming that the primary winding is connected to the input voltage supply, and using equation (1), we can calculate the ratio of N₂ to N₁:
So, the ratio N₂/N₁ is 45.
Have a nice day!
Answer:
b
Explanation:
b. increased frequency and severity of forest fires
Because of the Global warming the forest fires have increased drastically. The recent fire in Amazon rain forest is an example of this. These burning forests emit a large amount of CO2 yet again and further causing more global warming. According a a recent data it is estimated that forest fire emit about 8 million tons of CO2 in the atmosphere in last 20 years. In,2017 total global CO2 emission has reached to 32.5 billion tons, according to IEA.
Answer:
20 N up
Explanation:
Since the object on the floor is sitting still. Based on Newton's law of force. Objects must have equal reaction and force against each other for still objects. So the answer is 20 N up. Since the force are equal on both sides making the object not moving.
Saturn is the second largest planet in our solar system. At an average distance of 800 million miles (1.3 billion kilometers) from Earth, Saturn is the farthest planet that can be seen without a telescope. Saturn is the sixth planet from the sun. Because Saturn is so far away from the sun, Saturn is considered one of the outer planets. Despite it's large size, Saturn is the least dense planet in our solar system!
