A leak means air escapes, so the car wouldn't brake.
Non clastic sedimentary rocks from chemical reactions, chiefly in the ocean. Nonclastic and clastic sedimentary rocks are the only members of the rock family that contain fossils as well as indicators of the climate that was present when the rock was formed.
A well tested concept that explains a wide range of observations is called a Scientific theory
It goes to rest
or it goes to motion
Answer:
7.7 GJ
Explanation:
Kinetic wnergy is given by
KE=½mv²
Where KE denote kinetic energy, m is the mass of object and v is velocity. Normally, m is in Kg and v in m/s
Conversion
Given speed of satelite in km/h, we convert it into m/s by multiply by 1000/3600
20000*1000/3600=5555.5555555555
Rounded off, m=5555.56 m/s
Substituting 500 kg for m and 5555.56 m/s for v then
KE=½*500*5555.56²=7,716,061,728.4 rounded off as
KE=7.7 GJ
