Answer:
Chemical Energy
A Brief Overview Of Chemical Energy
Chemical energy is simply energy that is stored in compounds or elements, specifically in the atomic bonds that connect atoms and molecules. In food, it's a form of potential energy because it's stored away.
Explanation:
The crate’s acceleration is gravity= 9.81m/s^2
The ball’s acceleration is also gravity=9.81m/s^2
Answer:
option (b)
Explanation:
Mass of moon = m
Mass of earth = 81.25 x mass of moon = 81.25 m
Radius of moon = r
radius of earth = 3.668 x radius of moon = 3.668 r
Frequency on earth = 2 Hz
Let the frequency on moon is f.
The formula for the frequency is given by
The value of acceleration due to gravity on earth is g.
ge = G Me / Re^2
ge = G x 81.25 m / (3.668 r)^2
ge = 6.039 x G m / r^2 = 6.039 x gm
ge / gm = 6.039
Now use the formula for frequency
fm = 0.814 Hz
If you fly a spaceship to Vega at 0.999c, you will measure the distance to be much less than 25 light years.
Most space objects use light-years to represent their distance. Light-years are the distance that light travels during the year on Earth. Light-years are about 6 trillion miles (9 trillion km). This is a 6 followed by 12 zeros.
At the same speed, a movement equivalent to one light-year takes about 11.3 billion days. Life expectancy for Americans is currently estimated at 78.74 years, which is equivalent to 28,740 days. Therefore, to get there, you need to live about 400,000 times as long as the average American.
