The muscles of the body are part of the musculoskeletal system but would not operate without the nervous system providing the impulses that cause the muscles to act. Correct answer: C The nervous system controls all activities within the human body, including the muscles. It sends messages between the brain and the muscles very quickly using nerve impulses (action potentials).
Nervous is the system that provides impulse
Answer:
207.50°C
Explanation:
Mass of metal (M1) = 440g
Volume of water = 400mL
Initial temperature of water (T2) = 20°C
Final temperature of the mixture (T3) = 35.80°C
Specific heat capacity of the metal (C1) = 0.3850J/g°C
Specific heat capacity of water = 4.184J/g°C
Density of water = 1g/mL
Temperature of metal (T1) = ?
Heat lost by the metal = Heat gained by the water
Q = MC∇T
Q = heat energy
M = Mass
C = specific heat capacity
∇T = change in temperature
M1C1(T1 - T3) = M2C2(T3 - T2)
M2 = ?
Density = mass / volume
Mass = density * volume
Mass = 1g/mL * 400mL
Mass = 400g
M1C1(T1 - T3) = M2C2(T3 - T2)
400 * 0.3850 (T1 - 35.80) = 400 * 4.184 * (35.80 - 20)
154(T1 - 35.80) = 1673.6 * (15.8)
154T1 - 5513.2 = 26442.88
154T1 = 26442.88 + 5513.2
154T1 = 31956.08
T1 = 31956.08 / 154
T1 = 207.50
The initial temperature of the metal was 207.50°C
Sodium Chloride (NaCl)
B.
Vinegar (CH3COOH)
C.
Baking Soda (NaHCO3)
D.
Bleach (NaClO)
Sodium Chloride (NaCl) can be classified as a salt
Explanation:
Sodium chloride is an "ionic compound" is known as salt. The ratio in which the sodium(Na) and chloride(Cl) present in sodium chloride in NaCl is 1:1. It is found in seawater and is accountable for the salinity of the seawater. Also, NaCl is the extracellular fluid for various multicellular organisms.
When refined, it becomes in its 'edible' form and is used in food preservatives. Whereas, the large quantity of sodium chloride is used in various industries.
B a nonmetal bonds with another nonmetal
C a metal bonds with a nonmetal
D three nonmetals bond together
Answer: the reason why the balance increases is because it is heavier so that's why it increases more
Explanation: the definition for balance is the ability to move or to remain in a position without losing control or falling. : a state in which different things occur in equal or proper amounts or have an equal or proper amount of importance.
Mass is the amount of matter something is made from. Big things are generally more massive than small ones. If you have a lump of iron or copper and take it to different places on Earth (or even the Moon) to measure it's mass, you'll always get the same result.
Weight is a measurement of how much the force of gravity acts on a given amount of mass. The force of gravity varies slightly all over Earth so, while your lump of iron has the same mass, its weight varies: it might weigh a little bit more in Bangladesh than it does in Tibet. What about on the Moon? Gravity is about one sixth the strength on the Moon as it is on Earth. So things weigh only one sixth as much on the Moon as they do on Earth, even though their mass is exactly the same in both places. Why are things heavier on Earth? Essentially because Earth is so much more massive than the Moon. It attracts objects with more force—and that gives them more weight.
hope this helps you!!!!!!!!!!!!!!!!!
