Pivoting is moving around while _______________ Group of answer choices One foot is ot the ground at all times both feet are on the ground and stationary Jumping around while dribbling shooting the ball
Answer:
sounds like "Jumping around while dribbling shooting the ball"
Answer: One foot is it the ground at all times
Explanation:
Pivoting is keeping either your right or left foot on the ground while your opposite foot is moving, you may move in a circle. But if you take a step with the foot that is not supposed to move, you are traveling and it will be a foul. Pivoting is meant to get a pass off or a shot.
A car is driving along a road at a speed of 50 km/hr. How far will the car travel in 5 hours?
Answer:
I think it's 250
Explanation:
If the car is traveling 50 km/hr that means every hour, the car drives 50 km. So if you want to know how far it will go in 5 hours you do 50x5.

What causes the apparent colors of the objects we see?
Answer: The human eye and brain transform light into color. Allowing us to see them.
Explanation: Light receptors within the eye turn light into color. The color that is reflected off of an object, is what we see. Hope this helps.
The apparent colors of the objects we see causes due to reflection of the light which they absorb and emit.
What is reflection?Reflection is the change in direction of a wavefront which occurs at an interface present between the two different media so that the wavefront of the wave returns into the medium from which it has been originated. Common examples of reflection include the reflection of light, sound wave and water waves.
The color of an object is the wavelengths of light waves that it reflects. The reflection is determined by the arrangement of electrons in the atoms of that substance which will absorb and re-emit photons of particular energy levels according to the quantum laws.

heat engine operating between 100 °C and 700 °C has an efficiency equal to 40% of the maximum theoretical efficiency. How much energy does this engine extract from the hot reservoir in order to do 5000 J of mechanical work?
Answer:
Explanation:
Theoretical efficiency = T₁ - T₂ / T₁ where T₁ and T₂ is absolute temperature of hot and cold end of the heat engine.
= 600 / (273 + 700 )
= 600 / 973
= .6166
operating efficiency = 40% of .6166
= .4 x .6166
= .2466 = 24.66 %
efficiency = work output / heat input
= 5000 / heat input = .2466
heat input = 5000 / .2466
= 20275.75 J .
HEAT EXTRACED = 20275.75 J.

Answer:
1.86 [tex]m/s^{2}[/tex]
Explanation:
Acceleration = [tex]\frac{Force}{mass}[/tex]
Force = 11N
Mass = 5.9 kg
∴ Acceleration = [tex]\frac{11}{5.9}[/tex]
= 1.86 [tex]m/s^{2}[/tex]
Explain why teens are especially weak at impulse control

In many areas electricity is produced by huge generators close to dames. What function does a large volume of moving water have in generating electricity?
Answer:
To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.
