Answer:
3
Step-by-step explanation:
one day is 24 hours which is 2 times 12, so in two days there are 4 12-hour so divide 48 by two four times:
48/2=24
24/2=12
12/2=6
6/2=3
Answer:
We use Newton's second law of motion, which states that,
F
=
m
a
where:
F
is the net force applied in newtons
m
is the mass of the object in kilograms
a
is the acceleration of the object in meters per second squared
So, we get:
F
=
5
kg
⋅
10
m/s

=
50
N
(
∵
1
N
≡

Step-by-step explanation:
Answer:
<em>k = - 7.5 </em>
Step-by-step explanation:
Slope "m" of a line through points
(
,
)
(
,
)
is m =
Slopes of perpendicular lines are opposite reciprocal:
= - 1
~~~~~~~~~~~~~~~
The slope of a line through points (0, 7) and (2, 10)
=
=
Slope of perpendicular line through points (3, 5) and (k, 12) is
=
or
=
=
2(k - 3) = - 21
k - 3 = - 10.5
<em>k = - 7.5</em>
