What are Newtons Laws famous for
Answer:
Why are Newton's laws of motion important? Newton's laws of motion are important because they are the foundation of classical mechanics, one of the main branches of physics. Mechanics is the study of how objects move or do not move when forces act upon them.

Different between sound wave and water wave
Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They're also called longitudinal waves because the air vibrates along the same direction as the wave travels.

An amateur astronomer has just discovered a dwarf planet in an orbit past Pluto. Choose the best unit of measure to describe how far out in the solar system it is from the Sun.
A measuring cylinder contains 80 cm3 of a certain liquid. The liquid is poured
into an empty beaker of mass 48 g. The total mass of the beaker and the liquid
was found to be 136 g.
(a) Calculate the mass of the liquid in grams.
(b)Calculate the density of the liquid in gcm-3
Answer:
1.5 g/cm
3
Let d be the density of fluid.
So , Initial reading of balance, F
1
=30dg N
After the level reaches 50cm
3
Final reading of balance , F
2
=50dg N
Given that difference between final and initial reading is 30g
i.e, F
2
−F
1
=30 g
⟹50dg−30dg=30g
⟹20dg=30g
⟹d=
20g
30g
⟹d=1.5g/cm
3
So, density of fluid is 1.5g/cm

A cliff diver dove off a cliff at 8 m/s and landed in the water 21 m away from the cliff. How high is the cliff?
The vertical height of the cliff on which the diver drove off is 33.76 m.
The given parameters;
horizontal velocity of the diver, v = 8 m/shorizontal distance traveled by the diver, X = 21The time of motion of the cliff diver is calculated as follows;
[tex]t = \frac{X}{v} \\\\t = \frac{21}{8} \\\\t = 2.625 \ s[/tex]
The vertical height of the cliff is calculated as follows;
[tex]h = v_0_y t + \frac{1}{2} gt^2\\\\h = 0 + 0.5 \times 9.8 \times 2.625^2\\\\h = 33.76 \ m[/tex]
Thus, the vertical height of the cliff on which the diver drove off is 33.76 m.

Composition varies in the asteroid belt. Inner-belt asteroids tend to be rich in ____. Outer-belt asteroids tend to be rich in ____.
Inner-belt asteroids tend to be rich in SILICATE, whereas outer-belt asteroids tend to be rich in CARBON. An asteroid is a rocky object (much smaller than a planet), which orbits around the Sun.
The asteroids are composed of different elements (e.g., carbon, nitrogen, hydrogen, oxygen, silicate, etc).
The asteroid belt is a region in the Solar System, located between the orbits of Mars and Jupiter.
The size of the asteroids localized in the asteroid belt range from a few meters to almost 1000 kilometers (km) wide.
Approximately half mass of the asteroid belt is composed of only four asteroids (i.e., Ceres, Vesta, Pallas, and Hygiea).

Eva's pillows are really old and very flat. She is very used to them, so she thinks that they are fine. What would be a healthier option?
А. Fuller pillows that keep her neck straight
B. Stacking pillows so that her head is elevated.
C. Eliminating pillows and just sleeping on the mattress.
D. Using the pillows to get her feet higher than her head.
Answer:
I think c
Explanation:
have a good day/night/ whatever
Fuller pillows that keep her neck straight. The correct option is A.
Thus, Broader pillows that properly support her neck and head would be a better choice. Better sleeping posture and a lower incidence of neck and back pain can both be encouraged by pillows that keep the neck and spine in their natural alignment.
Flat pillows could not offer enough support, which could result in poor alignment and long-term discomfort or suffering.
Stacking pillows in Option B may provide some elevation, but it might not necessarily provide the essential neck and spine support. Option C (without using pillows) can fail to give the head and neck the necessary support and cushioning.
Thus, Fuller pillows that keep her neck straight. The correct option is A.
