Answer:As the Sun moves throughout the day, some plants can follow it. This is called <u><em>solar tracking.</em></u>
Explanation:
There are flower which tracks the position sun are called heliotropism or solar tracking. flowers.These are the flower which face their bloom side towards the sun to maximize the photosynthesis.The most common example of this is Sun flower.
Answer:
around the nuclei of each atom
Explanation:
B. The kuiper belt forms a sphere around the Sun.
2ii) the national grid uses high voltages and low currents to reduce thermal energy transfer from the wires/cables
Answer:
The one that is 100 cm from the center.
Explanation:
Given that merry-go-round means moving at uniform circular motion or constant angular speed. Hence the person who is closer to the center is moving at a slower speed, while the one far away from the center has a larger linear speed because he has moved a long distance in the same amount of time, despite being on these objects.
To illustrate
A with the 50 cm
B with the 100 cm
Hence, to get speed, we have
A = 2 * pi * 50 / T
B = 2 * pi * 100 / T
And by the explanation of angular speed
We have w = 2*pi/T where w is the angular speed in radians/s
Hence we have
A = 50w
B = 100w
Therefore, the one that is 100 cm from the center has a larger linear speed.
