Answer:
As we navigate down a group the atoms get bigger and bigger with more and more electrons. This means the outermost electrons get further and further away from the positively charged nucleus.
Answer:
v = 66.7 m/s
Explanation:
Given that,
The length of steel cable, L = 600 m
Diameter = 1.2 cm
It is observed that it took 18 s for the pulse to return.
The time taken to cover 600 m will be :
t = T/2
t = 9 s
Let v be the of the pulse. We know that,
So, the speed of the pulse is equal to 66.7 m/s.
Answer:
Because it is said that the earth rotates and revolves around the sun and moon so it is impossible for the earth not to be spinning.
Explanation:
Bella’s average velocity is about 0.693 meters per second.
To find the average velocity, you must divide the distance by the change in time, which should look like v=d/t
Here is how you set up the equation-
v=6.1/8.8
Once you divide 6.1 meters by 8.8 seconds, you should get a number that looks like 0.69318182.... however, I just rounded it to 0.693 meters per second. You can round it to whatever you like.
Hope this helped! If you have any questions about what I mentioned in my answer or explanation, feel free to comment on my answer and I’ll try to get back to you!
