Shadows are formed when an opaque object or an object that doesn't allow light to pass through is in the way or infront of etc. a source of light.
Answer:
According to Hook's law, we know,
strain/stress =Constant
Explanation: So, the ratio between stress and strain is always constant.
So, if stress is increased, then strain changes in that way so that this ratio always remains constant.
Answer:
Potentiation, habituation, and sensitization are three ways in which stimuli in the environment produce changes in the nervous system.
The force exerted on the cart 2 during the collision is 2 N.
The given parameters:
- <em>Mass of cart 1 = m1 = 1 kg</em>
- <em>Mass of cart 2 = m2 = 2kg</em>
- <em>Force applied on cart 1 = 2 N</em>
According to Newton's third law of motion, action and reaction are equal and opposite. The force exerted on cart 1 is equal in magnitude to the force exerted on cart 2 but in opposite direction.


Thus, the force exerted on the cart 2 during the collision is 2 N.
