Answer:

The answer is 0.12.

Explanation:

The least number of significant digits in the problem determines the number of significant digits in the answer in any multiplicantion/division problem. So for 15.0/124 there would be 2 significant digits in the answer since 15.0 has the least number of sig digs.

A hill that has a 36.1% grade is one that rises 36.1 m vertically for every 100.0 ml of distance in the horizontal direction. At
GaryK [48]

Answer:

angle is 19.85°

Explanation:

given data

grade = 36.1 %

vertically distance y = 36.1 m

horizontal distance x = 100 m

to find out

angle

solution

we know that according to question here

it make a triangle shape that contain 100 m base and height 36.1 m

and make angle with base is θ

so by triangle we know here

tanθ = y/x   ..........1

so we now put x and y and find θ

tanθ = 36.1 / 100

tanθ = 0.361

θ = 19.85°

so angle is 19.85°

A 50Kg girl jumps off a 5-meter-high diving board. What is her kinetic energy right before she hits the water?
Kryger [21]

Answer:

2450 J

Explanation:

Given that,

A 50Kg girl jumps off a 5-meter-high diving board.

We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,

K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J

So, her kinetic energy right before she hits the water is equal to 2450 J.
