Answer:
2.A flowerpot falling from a balcony
Explanation:
Potential energy is the internal energy within a body at rest or at a height above the ground. In this case of the falling flowerpot, the flowerpot initially has a potential energy due to its position on the balcony above the surface of the earth. As the flowerpot falls, the work done against gravity in taking the flowerpot to this height on the balcony (equivalent to the potential energy) is transformed into the kinetic energy of motion as the flowerpot falls down through the height.
Answer:
In any specified solar cycle, the highest number of sunspots is referred to as "solar maximum." The lowest number is referred as "solar minimum."
Explanation:
Around every 11 years, the sun passes through a solar cycle. The cycle is defined by increasing and decreasing sunspots— noticeable on a sun's surface as dark imperfections, or photosphere.
In any specified solar cycle, the highest number of sunspots is referred to as "solar maximum." The lowest number is referred as "solar minimum." The latest solar minimum was obtained in 2008
Answer is 5 watts.
Using the equation:
w=pt
W = work done (J)
P = power (Watts)
T = Time (s)
Substitute the values into the equation.
100 = 20p
Power = 5 watts
Answer:
120
Explanation:
because if it was 60 it would have been 5 kilometers but ten is double so just double the 60 to 120 kilometers per hour
Fulcrum need to be positioned balanced with weight on both the sides following law of lever.
What is the physical law of the lever?
- It is the foundation for issues with weight and balance. According to this rule, a lever is balanced when the weight multiplied by the arm on one side of the fulcrum, which serves as the pivot point for the device, equals the weight multiplied by the arm on the opposing side.
- The lever is balanced, in other words, when the sum of the moments about the fulcrum is zero.
- The situation in which the positive moments (those attempting to turn the lever clockwise) equal the negative moments is known as this (those that try to rotate it counterclockwise).
- Moving the weights closer to or away from the fulcrum, as well as raising or lowering the weights, can alter the balance point, or CG, of the lever.
