The velocity of the ball after it hits the bottle is 15.8 m/s

Let m₁ represent the mass of the ball, m₂ the mass of the bottle, u₁ the velocity of ball before impact, u₂ the velocity of bottle before impact, v₁ the velocity of ball after impact and v₂ the velocity of bottle after impact.

Given that:

m₁ = 0.7 kg, m₂ = 0.15 kg, u₁ = 22 m/s, u₂ = 0, v₂ = 29

momentum before impact = momentum after impact, hence:

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

0.7(22) + 0.15(0) = 0.7v₁ + 0.15(29)

0.7v₁ = 11.05

v₁ = 15.8 m/s

Therefore the velocity of the ball after it hits the bottle is 15.8 m/s

Answer:

I guess it is the reason

Explanation:

A dam is thicker at the bottom than at the top because the forces exerted are strongest close to the ground. Water pressure increases proportionally with depth, so the lower portion of the dam has greater water pressure exerted upon it. The increasing thickness of the lower dam also helps it support its own weight.

This is because of Pressure.

Pressure is directly proportional to depth and the deeper the length the high the pressure. Thus at the bottom, water pressure is very high and the walls must be made thicker to accommodate that pressure.

Answer:

A force unit is defined as the product of a mass unit and a unit of acceleration.

Answer:

Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.

Explanation:

Force = M (Mass) * A (Acceleration)

The SI unit of Mass = KG

S.I. unit of acceleration is m/sec/sec = m/sec2

Hence, Unit of force is Kg m/Sec2

Since force is used so often, S. I. gives this unit a special name:

1 Newton = 1 kg m/sec2

Explanation:

Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.

Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.

The answer to your question is the Photoelectric effect.

Explanation:

The initial velocity of the book before its hits the ground is 14.2 m/s.

The given parameters;

The initial velocity of the book is calculated as follows;

h = ut + ¹/₂gt²

where;

1.5 = 3u + (0.5 x 9.8 x 3²)

1.5 = 3u + 44.1

3u = 1.5 - 44.1

3u = -42.6

[tex]u = \frac{-42.6}{3} \\\\u = -14.2 \ m/s\\\\u = 14.2 \ m/s \ downwards[/tex]

Thus, the initial velocity of the book before its hits the ground is 14.2 m/s.

Answer:

If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision....What happen to the kinetic energy of its velocity become double ? The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy. Hence, when velocity is doubled, kinetic energy becomes 4 times.

Answer:

0.1962N.

Explanation:

Weight is a force, so we use newtons second law which states F=ma. So the weight of a watermelon on earth is 2kg x 9.81m/s², which is 19.62N (newtons). On the moon it weighs 2 x 1.63 which is 3.26N.

The weight of the pen is 0.02 x 9.81, which is 0.1962N. If the pen is not to fall the frictional force needs to be equal to this force,

so the answer is 0.1962N.

Answer:

P1 = momentum before collision = .5 kg * .32 m/s = .16 kg-m/s

Momentum is conserved

P1 = P2 = V * (M + m) = .16 kg-m/sec

V = .16 kg-m/sec / (.5 kg + .3 kg) = .2 m/sec

Answer:

Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.

Our Earth is a rotating planet. Fast moving air is deflected by the Coriolis effect, except exactly on the equator. This defines the direction of cyclones, hurricanes, and typhoons rotation. The wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.

The high is west of you, and the low is east of you. (If you're in the northern Hemisphere.)

The ball raised up the hill is given gravitational potential energy, which

causes it to roll spontaneously down the hill.

The statement that explains whether the ball rolling down the hill

experiment should be used is; The experiment shows the ball falls toward

the bottom of the hill, so it provides direct evidence that gravity pulls an

object downward. They should use it.

Reason:

The equation for the velocity of a ball falling down a hill is [tex]v = \sqrt{\dfrac{10}{7} \cdot g \cdot h}[/tex]

Therefore, by increasing the height from which the ball rolls down the hill,

the velocity of the ball increases, which indicates that the ball is

accelerating, and therefore, being acted on by a force, the force of gravity.

Therefore;

Given that the ball falls or moves with increasing speed towards

the bottom of the hill, which shows that the motion is due to Earth's pull

known as the gravitational force, the experiment should be used.
