9. A box is pushed 1.5 m to the right in 5 s. What is the box’s average speed to the nearest hundredth of a m/s? *
poizon [28]

Answer:

s = 0.30 m/s

Explanation:

Given data:

Distance travel = 1.5 m

Time taken = 5 s

Average speed of box = ?

Solution:

s = d/t

s = speed

d = distance

t = time

by putting values,

s = 1.5 m/ 5 s

s = 0.30 m/s

Which set of coefficients will balance this chemical equation?
Katarina [22]

Answer:

B 1,3

Explanation:

Count the atoms on each side of the arrow, they have to be equal

After arrow

2x C

6x O

4x H

Before the arrow

2x C - correct, as it is the only compound with C then there must only be 1 mole of it.

This is also the correct amount of H

We need 6x O total so 6/2 = 3

So there are 3 moles of O
