Larry, a 10-year-old, first sees two identical glasses with water at the same level;then, the water from one of the short, wide glasses is poured into a taller, thinner glass.Larry will likely conclude that <span>a. there is more water in the taller, thinner glass</span>
Sorry if this answer is a bit late...
We know that the volume of the water is 0.5 cube meters.
The density of water is 1.000 g/m^3 (that's the real density of water... maybe typos?)
The density of ice is 0.900 g/m^3 (that's the approximate density of ice)
First, let's multiply the volume of water by the density of the water to get the mass, since we know that the mass does not change with the ice gets frozen.
0.5 * 1.000 = 0.500 g
Now, let's divide that by the density of ice to get the volume of the ice.
0.500 / 0.900 = 5/9 cube meters
≈ 0.556 cube meters.
The volume of the ice is 5/9 or 0.556 cube meters.
Have an awesome day! :)
(1) The ball is in the air for <u>1.4 seconds.</u>
(2) The horizontal velocity of the ball as it rolls off the table is<u> 6.32 m/s.</u>
(3) The vertical velocity of the ball right before it hits the ground is <u>13.72 m/s.</u>
(4) The horizontal velocity of the ball right before it hits the ground is<u> 6.32 m/s.</u>
(5) The initial vertical velocity as soon as the ball comes of the cliff is <u>13.72 m/s.</u>
<h3>What is the time of motion of the ball?</h3>
The time of motion of the ball is calculated by applying the following equation.
t = √(2h/g)
where;
- h is the height of the cliff
- g is acceleration due to gravity
t = √(2h/g)
t = √(2 x 9.63 / 9.8)
t = 1.4 seconds
The horizontal velocity of the ball is calculated as follows;
v = d/t
where;
- d is the horizontal distance travelled by the ball = 8.85 m
v = 8.85 m / 1.4 s
v = 6.32 m/s
The vertical velocity of the ball before it hits the ground is calculated as;
vf = vi + gt
vf = 0 + 9.8 x 1.4
vf = 13.72 m/s
The horizontal velocity of the ball right before it hits the ground is calculated as;
the initial velocity of a projectile = final horizontal velocity
vxf = vxi = 6.32 m/s
The initial vertical velocity as soon as the ball comes off the cliff = final vertical velocity = 13.72 m/s

Answer:
Correct answer: The fourth claim
Explanation:
No claim is most accurate but if you have to choose the best from the bad one, it's fourth - Its height decreased as its motion increased.
The potential energy depends from height Ep = m g h and kinetic
energy depends besides mass from velocity (motion) Ek = m v²/ 2
God is with you!!!
