I think that answer would be C
Answer:
yes
Step-by-step explanation:
because its true
![\frac{15}{8} = \frac{80}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B15%7D%7B8%7D%20%3D%20%5Cfrac%7B80%7D%7Bx%7D%20)
At this point in time, you can use a technique called cross-mutiplication, where you say that
![15*80=8x](https://tex.z-dn.net/?f=15%2A80%3D8x)
, and
![1200=8x](https://tex.z-dn.net/?f=1200%3D8x)
at this point in time, you can devide each side by 8 and solve
Answer:
49N
Step-by-step explanation:
Step one
Given
When the force of 63 N acts on a certain object
the acceleration of the object is 9/ms^2
Firstly, we need to calculate the mass m
F=ma-------1
m= F/a
m= 63/9
m= 7kg
Step two:
Also, if the acceleration of the object becomes 7 m/s^2
then the force
Note: the mass remains the same= 7kg
F=ma
F=7*7
F= 49N
