Which of the following are scalar quantities? select all that apply

1. 150 grams
2. 5,280 miles up
3. 2 doors up to the right
4. a 5k race
5. 34 steps

1, 4, 5, see the explanation below

Explanation:

We must remember that scalar magnitudes are distinguished by having only a physical quantity, that is, they have no sense or direction as an example of scalar quantities, we find mass, temperature, energy, specific heat, power among others.

1 . 150 [grams] , because is a mass =  scalar

4. 5 kilometer [race], is an amount = scalar

5. 34 steps, is an amount = scalar

Number 2, and 3 are vectors because they have amount and direction.

30°

Explanation:

It will be the angle that it strikes an object at [30°].
