Answer:
60N
Explanation:
force = mass * acceleration
force = 12 * 5
force =60N
The answer is B. As the element X is from group two. This means two electrons can be lost. However nitrogen is from group 5 . You need three more electrons to fill the electron shell. Therefore, you need to find the LCM of 2and 3,which is six. 6over 2 is 3 . Which means you need three element X
Well they could go down a hill to gain more kinetic energy.
The diameter of the reflecting surface of spherical mirror is called its aperture. Mirrors whose aperture is much smaller than its radius of curvature, we use R=2f.
Answer:
Acceleration is the rate of change in velocity.
Explanation:
For example if you were riding in a car the change in velocity which is defined as an speed in direction. So if you were in a car and the car went from 30 MPH to 40 MPH the speed of the car has accelerated giving you acceleration.
