A baseball player hits a ball with 36 N of force. With that force, it causes the ball to accelerate at 120 m/s2. What is the mass of the baseball?
Answer:
0.3 kg
Explanation:
This can be dealt with using (a simplified version of) Newton's Second Law:
Force = mass x acceleration
We need to re-arrange the formula to get the mass of the ball isolated, on its own side of the equation. So we get:
mass = force/acceleration
So, now we just need to substitute the number we do have to get:
mass = 36/120 = 0.3 kg

supermarket is pure honey or not.
Answer:
i would test it and get real honey to see if the ingredients are the same
Explanation:
Explanation:
Water Test: In a glass of water, put a spoon of honey, if your honey is dissolving in water then it's impure. Pure honey has a thick texture that will settle at the bottom of a cup or a glass. –Vinegar Test: Mix a few drops of honey into vinegar water, if the mixture starts to foam, then your honey is impure.

1. Imagine doing the same virtual experiment using wood as the bottom material, instead of glass or water. Predict how the light would interact with the wood.
The wood can't do the same function as done by the water and glass in the same virtual experiment due to its different chemical composition.
The light will not pass through the wood due to its translucent behaviour that prevents light to pass through it as compared to water and glass which are transparent materials and light can easily pass through it.
So using wood as a bottom material instead of glass and water will not perform the same function as perform by water and glass in the same virtual experiment so we can conclude that wood can't perform the same function in the experiment.

Why do planets orbit faster as they get closer to the Sun?
The orbit becomes smaller closer to the Sun.
The orbit becomes smaller closer to the Sun.
The eccentricity changes as the planet gets closer to the Sun.
The eccentricity changes as the planet gets closer to the Sun.
The force of gravity increases closer to the Sun.
The force of gravity increases closer to the Sun.
The Sun's magnetism causes a "sling shot" effect.
Explanation:
The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.

a scientist uses 52g of Na2SO4 for a chemical reaction. how many moles of Na atom does the compound contain a) 0.366 b) 0.732 c) 8.422 d)16.845
Answer:
b). 0.732
Explanation:
52g Na₂SO₄ x 1 mol Na₂SO₄ x 2 mol Na
------------------------- -------------------- = 0.732 mol Na
142.04 g Na₂SO₄ 1 mol Na₂SO₄
Atomic Mass Units
Na₂ = 22.99 x 2 = 45.98
S = 32.06
O₄ = 16 x 4 = 64
Na₂SO₄ = 45.98 + 32.06 + 64 = 142.04
There are 2 moles of Na in 1 mole of Na₂SO₄

Calcular el valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a una temperatura de 17° C.
El valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a una temperatura de 17°C es 47.56 atmósferas.
La presión osmótica se puede calcular usando la siguiente ecuación:
[tex] \pi = \frac{nRT}{V} [/tex] (1)
En donde:
n: es el número de moles = 2 moles
R: es la constante de los gases = 0.082 L*atm/(K*mol)
T: es la temperatura = 17 °C = 290 K
V: es el volumen = 1 L
Introduciendo lo valores anteriores en la ecuación (1), tenemos:
[tex] \pi = \frac{nRT}{V} = \frac{2 moles*0.082 L*atm/(K*mol)*290 K}{1 L} = 47.56 atm [/tex]
Por lo tanto, la presión osmótica es 47.56 atmósferas.

the source of gases for the secondary atmosphere of the earth was _______
The source of gases for the secondary atmosphere of the earth was Volcanic Eruptions.
What is Secondary Atmosphere ?
The scientist think that the atmosphere today is completely different from what it used to be originally and therefore they call it secondary atmosphere.
Internal volcanic activity or the deposit of debris from comet collisions produce a secondary atmosphere.
The secondary atmosphere is thought to have formed as a result of the numerous volcanic eruptions that occurred from the start of Earth's early periods.
Although each volcano is unique, they all emit gases such as H₂O, CO₂, SO₂, H₂S, HCl, N₂, NO₂, and others.
These gases are formed due to melting of the Earth's crust.
Volcanic activity renew the atmosphere's molecules.
These molecules are not the Nitrogen and Oxygen that make up the atmosphere today.
