Answer:
The correct answer is c. When the balloon hits the ground, the rubber envelope stretches, storing elastic potential energy; this elastic potential energy is converted to the gravitational potentiaL
Explanation:
Let's analyze the situation of the globe
When it touches the ground, the part that is in contact decreases its velocity to zero, but the upper part of the ball continues to move, which creates that the molecules approach slightly, if we approximate the spring links, a repulsive force is created that after all the particles reach zero speed. The force of the springs moves the ball up until the force decreases to zero.
We can relate this force of Hooke with an elastic energy
This energy can be stored in the deformation of the system, as elastic potential energy, which is subsequently transformed into gravitational potential energy when the balloon is lifted.
The correct answer is c
Answer:
C = 5/9 x (F-32)
Explanation:
Formula for converting Fahrenheit (F) to Celsius (C):
C = 5/9 x (F-32)
The notation C represents the temperature in Celsius, and F is the temperature in Fahrenheit. After you know the formula, it is easy to convert Fahrenheit to Celsius with these three steps.
1.Subtract 32 from the Fahrenheit temperature.
2.Multiply this number by five.
3.Divide the result by nine.
For example, suppose the temperature is 98.6 degrees Fahrenheit and you want to know what the figure would be in Celsius. Use the above three steps:
C = 5/9 x (F - 32)
C = 5/9 x (98.6 - 32)
C = 5/9 x (66.6)
C = 37 C
The sailboat is about 0.83m/sec (rounded to the nearest tenth).
To find speed, you would calculate distance over time.
100 meters/120 seconds = 0.83 meters per second
Answer: C. physical fitness components
Explanation:
The physical activities includes daily activities which are part of daily routine. These include exercise, cooking, walking and others.
The physical fitness components can reduce the risk of beginning of the diseases and they will promote total health. These include cardiovascular endurance which provide safety against the heart diseases, muscular strength will allow the body to perform daily activities without any difficulties, flexibility, and body composition. The body composition will help to keep the body in proper shape.
