Answer:
Height will be equal to 0.4489 m
Explanation:
We have given mass of the toy m = 0.50 kg
Initial kinetic energy K = 2.2 J
We have to fond the height of the hill over which car roast
When car will roast the hill its kinetic energy will be converted into potential energy and at maximum height all kinetic energy will be converted into potential energy
So at maximum height
Acceleration due to gravity
So 0.50×9.8×h = 2.2
h = 0.4489 m
C: Contacting the facilities.
In one day a scientist can travel = 80 km
In 10 days. a scientist can travel = 80* 10
= 800 km.
Just learned this in chemistry. There are no subscripts, therefor each element only has 1 atom. Na has 1, O has 1 and H has one. There are 3 atoms.
