Answer:
B. plasma.
Explanation:
There are four main states of matter:
1. solid
2. Liquid
3. Gas
4. Plasma
Plasma is a state in which 99% of all matter present in the universe exists. It is highly conducting ionized gas. The electric field and magnetic field dominate the behavior of plasma. Plasma is electrically neutral but the positive and negative particles are unbound.
Plasma is the most common state of matter in the universe.
Any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. The force has the magnitude
F = mv^2 / r
Where f is the centripetal force
M is the mass
V is the velocity
R is the radius
19 N = m ( 0.54 m/s)^2 / 0.36 m
Solving for m
M = 23.5 kg
Answer:
23
Explanation:
True or False
Answer:
True
Explanation:
The object is at rest, which means it's not moving, so there is no net force on it, according to Newton's First Law.

Answer:
I think the answer is, Both humans and whale embryos have a tail and a backbone (I'm not sure).
Explanation:
This is because, both human and whale embryos have a tail and a backbone.
Hope this helps! :D
Gammadecay is the production of extremely high-frequency electromagnetic radiation . Gamma decay is the right answer from all types of decay.
Gammadecay is the production of extremely high-frequency electromagnetic radiation in order to stabilize the unstablenucleus. You must be well-versed in the various energylevels found in an atom.
The Nucleus has its own amount of energy. Gamma decay is the nucleus' method of transitioning from a higher energy level to a lower energy level by emitting high energy photons.
Hence gamma decay is the right answer for all types of decay. Because photons have no mass.

b. be 870 mm higher in the arm connected to the gas cylinder.
c. be 118 mm higher in the arm connected to the gas cylinder.
d. be 118 mm higher in the arm open to the atmosphere.
P = absolute pressure in gas container connected to open-end U-tube = 116 kPa = 116000 Pa
we know that, 1 atm = 101325 Pa and 1 atm = 760 mm of Hg , hence
P = 116000 Pa (1 atm/101325 Pa) (760 mm of Hg/1 atm)
P = (116000 x 760/101325) mm of Hg
P = 870.07 mm of Hg
P₀ = atmospheric pressure = 752 mm Hg
Level of mercury is given as
P' = P - P₀
inserting the values
P' = 870.07 - 752
P' = 118 mm
so correct choice is
d. be 118 mm higher in the arm open to the atmosphere.
The level of mercury in the tube would be 118 mm higher in the arm connected to the gas cylinder, as determined by converting kPa to mm Hg and calculating the pressure difference between the gas pressure and atmospheric pressure.
In order to solve this problem, we need to convert all units to the metric units system for consistency. First, let's convert the pressure of the atmosphere from mm Hg to kilopascals (kPa), knowing that one atmosphere which equals 760 mm Hg is approximately 101.3 kPa.
So, the atmospheric pressure is (752 mm Hg / 760 mm Hg) * 101.3 kPa ≈ 100.4 kPa.
The difference between the gas pressure and the atmospheric pressure gives the pressure of the mercury in the tube, since pressures are additive. So, the pressure difference is 116 kPa - 100.4 kPa = 15.6 kPa.
Finally, we convert this pressure in kPa back to mm Hg to get the height difference. By doing the inverse conversion, we get 15.6 kPa * (760 mm Hg / 101.3 kPa) ≈ 118 mm Hg. Therefore, the level of mercury in the tube will be 118 mm higher in the arm connected to the gas cylinder, corresponding to the option
c. be 118 mm higher in the arm connected to the gas cylinder.
