What is the base unit to mass measurement

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =
