Answer:
The total distance the bird travels is d.
Explanation:
Each train travels at the speed s. They will meet at the center, a distance d/2 (which is where the bird might be crushed). Each train travels the same distance d/2 in a time t which is also equal for both. This is also the time the bird spends travelling between them.
For any of the train, the time t is the distance divided by the speed.
The bird travels at the speed of 2s. Its distance is given by the product of its speed and the time taken.
According to the properties you provided, that should be metals.
Answer:
Explanation:
The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, sogginess. The atomic number of an element is the number of protons in the nucleus of an atom of that element.
Answer:
The acceleration towards the center will be
Explanation:
Given the running track is an oval shape, and the diameter of each half-circle is 74 meters.
Also, the runner took 1 minute and 40 seconds to complete 400 m one round of the track.
We need to find the acceleration towards the center.
First, we will find the speed.
Where is the speed.
is the distance covered by the rider that is 400 meters.
is the time taken by the rider to complete the lap which is 1 minute and 40 seconds. seconds.
So,
And
Where is the acceleration towards the center.
is the radius which will be the half of the diameter 74 meters.
Hence, the radius will be 37 meters.
So, the centripetal acceleration of the rider will be
Answer:
Juan's average speed is 2m/sec.
Explanation:
Since is formula for average speed is distance ÷ time, we can plug in our numbers.
100 = distance
50 seconds = time
100 ÷ 50 = 2
So, Juan's average speed is 2m/sec.
Hope this helps! Let me know if you have any other questions! :)
