Answer:
light travels faster than sound
Answer:
h = 0.0259 m
Explanation:
given,
diameter of the cone = 0.0208 m
radius,r = 0.0104 m
angle of inclination,θ = 18°
initial angular velocity, ω_i = 56 rad/s
final angular velocity ,ω_f = 0 rad/s
height, h = ?
Rotational kinetic energy
Moment of inertia of coin
so,
Transnational Kinetic energy
v = r ω
now,
using conservation energy
Kinetic energy of the coin is converted into the potential energy
KE_r + KE_t = PE
h = 0.0259 m
Vertical height gain by the coin is equal to 0.0259 m
The main units for acceleration are <span>the meter per squared second as told by Galileo Galilei. Although there can be more than one example, I consider this one to be correct. Hope it will help you in some measure.</span>
Answer:
B. 22,22,23,23,22,22,23
Explanation:
The standard deviation is a measure of dispersion or variability of a data set. In order to determine the data set that has the smallest standard deviation, we shall investigate on the ranges of the data sets given. The range of a data set is simply the difference between the maximum and minimum values in a data set. A data set that has a smaller range also has a smaller standard deviation.
From the alternatives given, the data set given by alternative B has the smallest range and consequently the smallest standard deviation.
The maximum value is 23 while the minimum is 22. The range is 1.
a measurable variable and a subjective opinion.
Explanation:
Testable hypothesis that leads to experiments usually describes a relationship between a measurable variable and a subjective opinion.
In testing a hypotheses through experiments, we often design our work to suit the use of two variables which are the measurable variable and the subjective opinion.
- This often takes the shape of dependent and independent variables in an experiment.
- Measurable variables can either be dependent, independent or controlled variables.
- The subjective opinion is the scientific logic that governs hows two or more variables are related.
