Answer:
The answer is "-72 k".
Explanation:
Please find the complete question in the attached file.
Given point:
Calculating the area:
![=i[8(0)-8(0)]-j[(0-0)]+k[(0-9(8))]\\\\=i[0-0]-j[(0)]+k[(0-72)]\\\\=i[0]-j[(0)]+k[(-72)]\\\\=-72 \ k](https://tex.z-dn.net/?f=%3Di%5B8%280%29-8%280%29%5D-j%5B%280-0%29%5D%2Bk%5B%280-9%288%29%29%5D%5C%5C%5C%5C%3Di%5B0-0%5D-j%5B%280%29%5D%2Bk%5B%280-72%29%5D%5C%5C%5C%5C%3Di%5B0%5D-j%5B%280%29%5D%2Bk%5B%28-72%29%5D%5C%5C%5C%5C%3D-72%20%5C%20k)
I would go with C but that's just my personal opinion, I chose C because she only did it to group A
Answer:
gravitational pull by earth and friction
Explanation:
When the ball is placed on tilted tale it starts rolling because of the force of gravity pulls it downward along the plane of table and frictional force produces torque which generate rotational motion as a result body will start rolling.
Push of the table will be used to generate frictional force f=μ.N

Answer:
a=12 m/s²
Explanation:
Newton's second law of motion states that the acceleration of a body is directly proportional to the force applied and takes place in the direction of force.
This can be summarized as: F=ma, where m is the mass of the object on which force F acts. a is the acceleration due to the force applied.
12N= 1kg×a
a=12N/1kg
a=12m/s²
