8.0 m/s if there is no air resistance. (B)
Less if there IS any air resistance.
Earth is divided into two hemispheres/coast. Which is south, north, east, and west.
California is west coast.
Answer:
<u></u>
- <u>1. The potential energy of the swing is the greatest at the position B.</u>
- <u>2. As the swing moves from point B to point A, the kinetic energy is increasing.</u>
Explanation:
Even though the syntax of the text is not completely clear, likely because it accompanies a drawing that is not included, it results clear that the posittion A is where the seat is at the lowest position, and the position B is upper.
The gravitational <em>potential energy </em>is directly proportional to the height of the objects with respect to some reference altitude. Thus, when the seat is at the position A the swing has the smallest potential energy and when the seat is at the <em>position B the swing has the greatest potential energy.</em>
Regarding the forms of energy, as the swing moves from point B to point A, it is going downward, gaining kinetic energy (speed) at the expense of the potential energy (losing altitude). When the seat passes by the position A, the kinetic energy is maximum and the potential energy is miminum. Then the seat starts to gain altitude again, losing the kinetic energy and gaining potential energy, up to it gets to the other end,
Answer:
Following are the solution to the given question:
Explanation:
Its best approach to this measurement ought to be to indicate that there was a mistake throughout the calculation, as well as the gathering of further details while researching cells for bacteria, directly measuring the cell length of a colony. This chart illustrates its data, which scientists have observed that there's still a measurement.
Answer:
Resistance of the light bulb = 1.33 ohm (Approx.)
Explanation:
Given:
Current in electric bulb = 2 Amp
Voltage in battery = 1.5 Volt
Find:
Resistance of the light bulb
Computation:
Resistance = Voltage / Current
Resistance of the light bulb = Voltage in battery / Current in electric bulb
Resistance of the light bulb = 2 / 1.5
Resistance of the light bulb = 1.33 ohm (Approx.)
