A ball hit on both arms at the same time below the waist in volleyball is considered a double hit, which is a violation of the rules. This means that the player allowed the ball to simultaneously touch both of their arms, causing the ball to come to rest momentarily, resulting in a fault.
What else can I help you with?
6 Put the following objects in order of increasing gravitational potential energies?
They all have the same gravitational potential energies.
When a metal and a plastic ball are dropped on the same height in the end they both have the same change in potential energy or momentum?
No. The change in potential energy and momentum both depend on the mass of the object, and the metal ball and plastic ball have different masses. What's the same for both of them is their acceleration while they fall, the time they take to reach the ground, the moment when they hit the ground, and their speeds when they hit the ground.
Compare the speed of a moving golf ball with the speed of a moving bowling ball if both balls have the same amount of momentum?
momentum=velocity x mass say a golf ball weighs 1 pound and the bowling ball weighs 5 pounds the golf ball would have to be moving 5 times faster than the bowling ball to have the same momentum
When dropped from a building a cricket ball and a football have the same velocity or they hit the ground at same instant which more correct answer?
Both the cricket ball and football will hit the ground at the same time, regardless of their velocities. This is because they are both subject to the same acceleration due to gravity, causing them to fall at the same rate.
If a green ball has a greater momentum that a orange ball and both balls are moving at the same velocity then?
The green ball would have greater mass than the orange ball. Momentum depends on both mass and velocity, so if they have the same velocity but different momentum, it means their masses must be different.
6 Put the following objects in order of increasing gravitational potential energies?
They all have the same gravitational potential energies.
Imagine an experiment in which a 16lb bowling ball and a 10lb bowling ball are dropped from the fifth floor at the same time The heavier ball will reach the ground first?
No. They will hit the ground at the same time. The inertia for the heavier ball will be greater, but the acceleration for both will be the same, and both would (if the air resistance is the same for both) hit at the same time.
Can you throw the ball at the player for an out in kickball?
Either, catch the ball when the infielders kick the ball; or hit the infielder with the ball when they are running to the bases.
What is the same about volleyball and soccer?
they both got balls
How are Pluto and Mars the same?
Pluto and Mars are the same in the following ways:They both orbit the sunThey are both ball-shaped
How is soccer and basketball the same?
in both games you try to get the ball and score
Are the upper ball joints on a vehicle the same on both sides?
Yes.
How is a stretched ruberband the same as a ball on a hill?
They both have potential energy.
Which will have the greater acceleration rolling down an incline plane a large ball or a small ball?
If they are both solid, and the incline is the same, the rate of acceleration will be the same.
What will hit the ground first a bowling ball or an apple?
Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.
Does a softer or harder golf ball bounce higher?
they both bounce about the same
Explain using Newton's second law Why can you throw a golf ball further than a bowling ball even though you throw both at the same angle and with the same amount of force?
both will have same kinetic energy ,so forward velocity will be lower for bowling ball , the time to go up then down to the ground under gravity will be the same for both, so distance = velocity * time , so lighter (golf)ball will travel further because its velocity is higher second thoughts, assume launch angle same for both, ball with greater launch velocity will travel further. (laws of ballistics) if work done on ball (f * d) is same on both , the lighter ball will have greater launch velocity, though both will have same kinetic energy at launch
