Answer:
When the mass is drawn upwards and let go, the force of gravity accelerates it,
Explanation:
if you send me the video i can give you a better answer its just hard without seeing it
Firstly, when we say precision, this means the level of detail of a number. On the other hand, significance means that how precise a number is written and accuracy is defined as how close the number is to an actual value. Significant figures represent the precision of a measurement and not its accuracy because when a measurement has a larger number of significant figures, it has a greater reproducibility <span>or precision because it has a smaller source of error in the estimated digit. Hope this answer helps.</span>
Answer:
This is a third class lever.
Explanation:
A third class lever is when the fulcrum is on one of the far ends, the load is on the other, and the effort is pushing up from the middle.
Answer:
The answer is 14.8 m/s.
Explanation:
Substituting 22.1 revolutions for f, 6.4 meters for R in Relation between velocity and frequency of motion.
V = (2π) ( 22.1) (6.4)
= ( 2π) ( 22.1 rev/ min) ( 1min÷ 60 s )(6.4)
= 14.8 m/s.
Answer:
Two off-centered spots in the first phase of the experiment; one centered spot in the second phase of the experiment.
Explanation:
If two particles are selected in which both have the same electron mass and the same velocity, but one of the particles has a charge and the other particle has a charge of 2e. During the first stage of the experiment, the two particles have an electric force equal to F = Eq in the entire vertical direction. The acceleration of particle is equal to a = (Eq)/m.
In the second part of the experiment, the magnetic field cancels the electric field. In this way, the electric force and the magnetic force cancel each other out. Therefore, the net force acting on each particle is equal to zero.
Because these two forces cancel each other out, the particles fail to create two off-center points on the screen in the second part of the experiment. Also, if the loads are different, the deviation is also different. In this way, an off-center point cannot be achieved in the first part of the experiment. There will be two off-center points.
