Your brain has time to move around and improve its abilities better. This relaxes the brain and pre prepares it for its job.
Answer:
31.3mph North
Explanation:
Given parameters:
Distance traveled = 1500miles
Time taken = 48hrs
Unknown:
Velocity of the group of explorers = ?
Solution:
Velocity is the displacement divided by the time taken. It is a vector quantity with both magnitude and direction.
So;
Velocity =
Displacement is the distance moved in a specific direction = 1500miles North
Insert the parameters and solve;
Velocity = = 31.3mph North
Answer:
A
Explanation:
I believe it is A because reflection is usually like a mirror or in water the other ones described are refraction or conversion. Hope this helps! :)
Answer:
A. 0.20 unpolarized and 0.80 plane polarized.
Explanation:
After passing through polaroid sheet , unpolarised portion will get reduced by half . So this portion becomes .20/ 2 = 0.10
The polarized portion can face two situation depending upon the angle of the polaroid.
It may either be cut off to zero. So total intensity of transmitted light wil be .10 + 0 = .10
It may or be passed fully . In that case total intensity of transmitted light will become 0 .10 +0.80 =0.90
Ratio of these two light of maximum and minimum intensity is 0.90 / 0.10 = 9.
Answer:
Nothin will move, it will stay the same since no force is greater than the other. it's "the same amount of force" which also means an equal amount of force
Explanation:
The forces are only equal if there is no acceleration (which in the game of tug of war, accelerating yourself and your opponent is the idea). If the force on the rope and the ground are both equal either nothing moves or some other force is being applied in the system.
Hope this helped!
