Answer:
1).....for the specific heat capacity(c) of water is 4200kg/J°C..
....guven mass(m)=320g(0.32kg)
...change in temperature(ΔT) =35°C
from the formula
Q=mcΔT
Q=0.32Kg x 4200kg/J°C x 35°C
Q=47,040Joules
Answer:
24 hours and 50 minutes
Explanation:
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
the instrument used to measure the volume of a liquid, mass, length, and density is a graduated cylinder
the main 3 units of measurement in the metric system are meters, grams, and liters
Answer: The complete nuclear symbol will be 
Explanation:
The nuclear symbol is written as: 
where Z= atomic number , A = mass number X = symbol of element
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For an electrically neutral atom,
Atomic number = Number of electrons = Number of protons = 8
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Mass number = 8 + 10 = 18
Thus complete symbol will be
