Answer:
C) the reactants have more potential energy than the products.
Explanation:
Answer:
When the spectral lines are absorption lines, the effect is called inverse Zeeman effect.
Answer:
If you punched thousands of holes in the aluminum foil, you would see thousands of small images in the viewer.
Explanation:
If thousands of holes is punched/perforated in an aluminum foil, such that there were more holes than foil.
Thousands of small images would be formed, which can be seen in the viewer. Aluminum foil has a good reflective property which allows the thousands of holes punched to reflect equal number of images, although the images are smaller in size than the original image size.
Answer:
It is Newton's first law of motion also referred to as the law of inertia.
Explanation:
Answer:
The magnitude of the radial acceleration is 0.754 rad/s²
Explanation:
Given;
radius of the flywheel, r = 0.2 m
initial angular velocity of the flywheel, 
angular acceleration of the flywheel, a = 0.900 rad/s².
angular distance, θ = 120⁰
the angular distance in radian = 
Apply the following kinematic equation to determine the final angular velocity;
The magnitude of the radial acceleration is calculated as;
Therefore, the magnitude of the radial acceleration is 0.754 rad/s²
