This study was aimed at testing the construct validity of the basketball basic motion skills test instrument (ITK GDBB). The research used descriptive method of 3 basketball experts in the city of Cimahi; 3 experts are the expert in basketball. The instrument used was the ITB GDBB developed by Silvy (2019) consisting of top passing, bottom passing, top service, bottom service, chest passing, bounding passing, overhead passing, and leading ball (dribbling). This instrument consists of 76 items that cover 4 domains in basketball, namely chest pass, overhead pass, bound pass, and dribbling. The validity method used the construct validity of different power types. For the reliability method, it used the Kuder Ricardson (KR) and Objectivity analysis. The results of the construct validity analysis of a total of 76 items show that the score is ranged from 0.67 to 1.00. The construct validity value of 71 items in the basketball game is in the high category (= 1.00), 5 items are in the sufficient category, the relativity score is ranged from 0.75 to 0.98, and the objectivity score is ranged from 0.89 to 0.95. The conclusion is that this test instrument can be used as a standardized basic motion skill test for standardized large ball games for validity in basic motion skills in basketball games for grade VII junior high school students.

How many significant figures are in the following measurements? a. 3000000000 m/sA bike rider accelerates uniformaly at 2.0m/s^2 in 7.0 s. What was the speed of the object after 2.0 seconds?
Answer: 1 sig fig
Explanation: because 0s aren‘t significant and yes decimal points matter but after the decimal it’s a 0. So it is 1. If it was 0.30 it would be 2 sig figs but 0.03 would be one sig fig.

If the strength of the sun's magnetic field decreased from its current level, why would the temperature of sunspots increase?
Magnetic field lines emerge from one sunspot and re-enter at the other spot. Also, there are more sunspots during periods of increased magnetic activity. At ...
The temperature of sunspots increases because magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.
What is the sun's magnetic field?The magnetic field of the sun has two poles, similar to a bar magnet. Every 11 years, at the peak of the solar activity cycle, the poles flip.
The magnetic field is carried away from the sun's surface and through the solar system by a solar wind made up of charged particles. The sun is more like a fluid than a solid ball.
Thus, the magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.

A sphere of radius r =34.5 cm and mass m = 1.80 kg starts from rest and rolls without slipping down a 30.0∘ incline that is 10.0 m long.
A.) calculate its translational speed when it reaches the bottom.
B.) Calculate its rotational speed when it reaches the bottom.
C.) what is the ratio of translational to rotational kinetic energy at the bottom?
Answer:
Explanation:
It depends on the construction of the sphere.
Let's ASSUME it is uniform construction with a moment of inertia (2/5)mR²
The Change in potential energy will equal the change in kinetic energy
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½((2/5)mR²)(v/R)²
2gh = v² + 2/5v²
2gh = 7/5v²
v = √((10/7)gh)
v = √((10/7)(9.81)(10.0sin30.0))
A) v = 8.37 m/s
B) ω = 8.37/0.345 = 24.3 radians/s
C) ½mv² / ½Iω² = mv²/Iω² = mv²/((2/5)mR²)(v/R)² = 5/2
Why are there fewer elements than there are compounds?
Compounds are 2 or more elements that are combined together to form a new substance. Why are there are more compounds than elements? Because elements can combine with more than just one element, thus creating a whole series of combination possibilities.

1.) can the helicopter take off with the person holding on?
2.) Why or why not? (answer in terms of forces and directions)
3.) how much force would the propeller need to produce to perfectly balance the forces on the helicopter?
Answer:
Explanation:
1) No take-off possible
2) The downward force is greater than the upward force.
3) 2000 + 950 = 2950 N upward

how do sound waves behave as a solid
a. they travel faster in a solid than other mediums
b. they travel slower in a solid than other solids
c. they stop when they hit a solid
d.sound waves behave the same in any medium
Answer:
A. They travel faster in a solid than other mediums
Explanation:
Sound waves travel faster in solids because the density of solids is higher than that of liquids which means that the particles are closer together and sound can be transmitted more easily.

A. the typical 90-minute sleep cycles of alternating REM and NREM are established.
B. about 50 percent of sleep time is spent in REM sleep and 50 percent is spent in quiet sleep that is very similar to NREM stages 1 and 2.
C. their sleep pattern is characterized by 60-minute sleep cycles, producing up to 13 cycles per day.
D. they will begin to experience their first dreams and nightmares.
Option D is correct. Around the age of five, children begin to experience their first dreams and nightmares
By the time children are five years old, several developments occur in their sleep patterns.
Option A is incorrect because the typical 90-minute sleep cycles of alternating REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) are not yet established at this age.
Option B is also incorrect as the sleep time distribution between REM sleep and quiet sleep (similar to NREM stages 1 and 2) is not necessarily equal at this stage.
Option C is inaccurate because 60-minute sleep cycles producing up to 13 cycles per day do not align with the typical sleep patterns of five-year-olds.
However, option D is correct. Around the age of five, children begin to experience their first dreams and nightmares.
This is an important milestone in their cognitive and emotional development, as it reflects the maturation of the brain regions involved in dreaming and the processing of emotions during sleep.
