Answer:
The angle is 
Explanation:
From the question we are told that
The distance of the dartboard from the dart is 
The time taken is 
The horizontal component of the speed of the dart is mathematically represented as
where u is the the velocity at dart is lunched
so
substituting values
=> 
From projectile kinematics the time taken by the dart can be mathematically represented as
=> 
=> 
![\theta = tan^{-1} [0.277]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%20tan%5E%7B-1%7D%20%5B0.277%5D)
The correct answer is that they would all hit the ground at the same time. If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. This statement follows from the law of conservation of energy and has been demonstrated experimentally by dropping a feather and a lead ball in an airless tube.
Answer:
Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
Explanation:
Sensation helps us to detect changes in our physical environment.
Sensation occurs in three steps,
- Sensory receptors, these detect stimuli.
- Sensory stimuli are converted into electrical impulses to be decoded by the brain.
- Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.
Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
