Answer:
Kinetic energy is referred to the energy associated with movement and or motion, thus the only object that is moving would be A boat sailing across the ocean.
Explanation:
Answer:
It is a technique called water displacement method
Mass of an irregular object can be measured using a physical balance
Explanation:
- It consists of a calibrated glass cylinder containing water.
- The initial level of water column is noted
- The irregular object is submerged into it. The water level rises.
- The level of the water column is noted.
- The difference between the final and initial level of the water column gives the volume of the irregular object.
- The method used to find the volume of irregular shaped object is called the water displacement method.
Answer: 6067.5 N
Explanation:
Work = Change in Energy. To start, all of the energy is kinetic energy, so find the total KE using: KE = 1/2(m)(v^2). Plug in 1980 kg for m and 15.5 m/s for v and get KE = 237847.5 J.
Now, plug this in for work: Work = Force * Distance; so, divide work by distance to get 6067.5 N.
Answer:
18 days
Explanation:
A person normally consumes 2200 Cal per day
An adult burns 2000 Cal per day normally
Energy converted to fat 2200-2000 = 200 Cal
Number of days will be given by
The number of days would be 18 days
