Depth perception is the way in which some animals, such as humans, can tell if a object is close or far away from them.
Answer:
Explanation:
The current from the battery always flows from the positive terminal of the battery to the negative terminal of the battery.
If we connect a red coloured wire to the positive terminal of the battery and black coloured wire to the negative terminal of the battery, and then reverses the wire to their respective terminals, then there is no change in the direction of flow of current. It does not matter that which wire is connected to the particular terminal. The current always flow from positive to negative terminal of the battery outside the battery.
Answer:
A= 61.35
B= -44.40
Explanation:
1. Using the components method we have:
Considering that the vector sum , then:
Then:
It means the value of x and y component is 0.
2. Determinate the equations that describe each component:
Form Eq. (1):
Replacing A in Eq. (2):
Replacing values of C, α and β in (4):
Replacing value of B in (3)
Explanation:
Explanation: When it is at the first point , it doesn't have a proper running force and energy is stored, therefore, potential energy is more. And at forth point, it has a large running force and it has now kinetic energy. And that's why point 1 has greater potential energy than point
