Answer:
The charge of an atom is the number of protons minus the number of electrons.
That is not true
They both have nuclei or we would not be living now
The amount of heat needed to raise the temperature of an object is obtained through the equation,
H = m(cp)(20) + m (heat of fusion) + m(cp) (dT)
where H is heat, m is mass, cp is specific gravity, and dT is the change in temperature. The specific gravity of water is 0.5 cal/g.C. The third term is for water and cp is equal to 1 cal/g.C. Substituting the values,
815 cal = (5 g)(0.5 cal/g.C)(20C) + (80 cal/g)(5 g) + 5(1)(T2)
The value of T2 is 73 degrees C.
Answer:
The answer is Observation.
For you to observe the things around you then you need to use all your sense organs....
Answer:
Explanation:
Given that,
Force applied to a soccer player, F = 56.6 N
The mass of the ball, m = 0.46 kg
We need to find the acceleration of the soccer ball. The force acting on the ball is given by :
F = ma
Where
a is the acceleration
So, the required solution is 
.
