You're driving a car that can climb the maximum gradient of 500m/km. the hill in front of you start at an elevation of 20 meter and reaches 500 meter. the total distance of the heel is 0.5 km? what is the gradient of the hill and will your car make it?

Answer : The gradient of the hill is 960 m/km and and he won't be able to climb.

Solution : Given,

Maximum gradient = 500 m/km

Total distance = 0.5 km

Initial elevation = 20 m

Final elevation = 500 m

Formula used :

Now put all the given values in this formula, we get the gradient of the hill.

Gradient of the hill is 960 m/km which is greater than the 500 m/km. So, he won't be able to climb.

Therefore, the gradient of the hill is 960 m/km and and he won't be able to climb.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
