A 1300 kg car starts at rest and rolls down a hill from a height of 10.0 m. It then moves across a
1 answer:
Answer:
0.51 m
Explanation:
Using the principle of conservation of energy, change in potential energy equals to the change in kinetic energy of the spring.
Kinetic energy, KE=½kx²
Where k is spring constant and x is the compression of spring
Potential energy, PE=mgh
Where g is acceleration due to gravity, h is height and m is mass
Equating KE=PE
mgh=½kx²
Making x the subject of formula
Substituting 9.81 m/s² for g, 1300 kg for m, 10m for h and 1000000 for k then

Answer:
Two moles of aluminum chloride are produced when six miles of hydrogen Chloride
react with plenty of aluminum
Explanation:
6 Moles of will only react with 2 moles of
irrespective of the number of moles of each compound present. The reaction wiil take place in this ratio only. The products produced will be 2 moles of
and 3 moles of
this ratio will also be constant.
So, six moles of hydrogen chloride will react with plenty of aluminum to produce many 2 moles of aluminum chloride
