The tangental acceleration of the flywheel of radius 2.12 cm with a final angular velocity of 1820 rev/min and an angular acceleration of 16.2 rad/s is 0.34 m/s².
What is tangental acceleration?This is the rate of change of tangental velocity of an object in circular motion.
To calculate the tangental acceleration, we use the formula below.
Formula:
a = αr............. Equation 1Where:
a = Tangental accelerationr = radius of the flywheelα = Angular acceleration of the flywheel.From the question,
Given:
r = 2.12 cm = 0.0212 mα = 16.2 rad/s²Subsitute these values into equation 1
a = (0.0212×16.2)a = 0.34 m/s²Hence, The tangental acceleration of the flywheel of radius 2.12 cm with a final angular velocity of 1820 rev/min and an angular acceleration of 16.2 rad/s is 0.34 m/s².

During the next hour, you stop for lunch and only travel 25 kilometers. What was your average speed?
Answer:
75 km/hour

This is not something that waves do because they need a medium to travel through, while particles do not.
How light travels in space?A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.
So we can conclude that electromagnetic waves like light do not require medium for its propagation.

In science, a new hypothesis must be (mark all correct answers):
1. falsifiable by experimental testing or observations.
2. completely consistent with all previous laws and theories of science.
3. possible to prove correct.
4. based solely on physical causes.
Answer:
1, 2, and 3.
Explanation:
Hypotheses must be able to be proven false, otherwise it’s a law. It must be consistent with other theories otherwise it’s not true, and it has to be possible to prove correct, otherwise it’s a theory.
The true statement is "Falsifiable by experimental testing or observations." The correct option is 1.
In science, a hypothesis is a proposed explanation or prediction for a phenomenon or set of observations.
A new hypothesis is a fresh idea put forth by a scientist to explain a phenomenon or observation that has not been explained or understood fully by existing scientific theories or hypotheses.
The new hypothesis should be based on previous knowledge and observations, and it should be testable and falsifiable through experiments or observations. Scientists use hypotheses to guide their research and develop theories, which are more comprehensive explanations backed up by multiple lines of evidence.
Therefore, only Option (1) is the correct answer.
