A 6-column table with 2 rows. The first column labeled number of washers has entries 1, 2. The second column labeled initial vel

ocity v subscript 1 (meters per second) has entries 0.11, 0.13. The third column labeled final velocity v subscript 2 (meters per second) has entries 0.28, 0.36. The fourth column labeled time to travel 0.25 meters t subscript 1 (seconds) has entries 2.23, 1.96. The fifth column labeled time to travel 0.5 meters t subscript 2 (seconds) has entries 3.13, 2.61. The sixth column labeled Acceleration a = StartFraction (v subscript 2 minus v subscript 1) over (t subscript 2 minus t subscript 1) EndFraction (meters per second squared) has entries 0.19 and empty. The acceleration of the car with two washers added to the string would be

Answer:

A) The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be  10  m/s2.

B) The mass of 3 washers, when converted to kg, is  0.0147  kg.

C) The applied force of 3 washers will increase the applied force on the car to 0.147 N.

Thich of the following is a chemical property2
Dimas [21]

Answer:

"Freezing point  and ability to react with oxygen" are chemical properties

Explanation:

The change of liquid into solid is the freezing point. The melting point is more than the freezing point in certain cases of mixtures for certain organic compounds like fats. As soon as the mixture freezes it becomes solid and which results in change in the composition from the liquid and solid in this way the it drastically reduces the freezing point. The melting point gets higher due to the pressure. This happens due to the release of heat of which results in the rise of temperature to the freezing point .Also the reaction of elements with oxygen which leads to formation of new substance is also an chemical property

If 507 g FeCl2 were used up in the reaction FeCl2 + 2NaOH Fe(OH)2(s) + 2NaCl, how many grams of NaCl would be made?
Ket [755]
Number of moles of FeCl2 used = mass/ molar mass 
Number of moles = 507/126.751 = 4.
If one mole of Fe reacts with two moles of sodium 
Then 4 moles of Fe produces 8 moles of sodium.
Number of moles of sodium = mass/molar mass
Molar mass of sodium chloride = 23 +35.5 = 58.5 g/mol
Hence mass = 8 * 58.5 = 468 g. Hence Option A.

7.The following symbol is used to represent the particles in what type of radiation?Select one:a. Alphab. Betac. Gammad. Neutron
laiz [17]

Explanation:

The emission of a beta particle is the result of the rearrangement of the unstable nucleus of the radioactive atom in order to acquire stability. For that, a phenomenon occurs in the nucleus, in which a neutron decomposes giving rise to three new particles: a proton, an electron (β particle), and a neutrino. The antineutrino and electron are emitted. The proton, however, remains in the nucleus.

The symbol is used to represent beta particles.

Answer: b. Beta
