Answer:
v = 16.98 km/s
Explanation:
Given that,
Distance, d = 4500 km
Time, t = 265 s
We need to find its average speed. The total distance covered divided by total time taken is called average speed of an object. So,
So, the average speed is 16.98 km/s.
1. Matter is anything that has mass and takes up space.
2. Electrons orbit around the nucleus.
3. protons and electrons
The basic monomer of a lipid is a triglyceride. It breaks down into one glycerol molecule and 3 fatty acid tails.
Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
Kinetic energy is the energy an object has due to its motion.
