Definition:
Speed = (distance covered) / (time to cover the distance).
Speed in the first example = (10 meters) / (1 second) = 10 m/s .
Speed in the second example = (20 meters) / (2 seconds) = 10 m/s.
Apparently, it is. This little exercise demonstrates it.
Answer:
the final temperature = 74.33°C
Explanation:
Using the expression Q = mcΔT for the heat transfer and the change in temperature .
Here ;
Q = heat transfer
m = mass of substance
c = specific heat
ΔT = the change in temperature
The heat Q required to change the phase of a sample mass m is:
Q = m
where;
is the latent heat of vaporization.
From the question ;
Let M represent the mass of the coffee that remains after evaporation is:
ΔT = 
where;
m = 2.50 g
M = (240 - 2.50) g = 237.5 g
= 539 kcal/kg
c = 1.00kcal/kg. °C
ΔT = 
ΔT = 5.67°C
The final temperature of the coffee is:
ΔT
where ;
= initial temperature = 80 °C
= (80 - 5.67)°C
= 74.33°C
Thus; the final temperature = 74.33°C
Answer: Not balanced
Explanation: In order to balance this equation the coefficients are the following:
6 CO2 + 6H2O = > C6H12O6 + 6O2
Answer:
D. It has a central nucleus composed of 35 protons and 45 neutrons,
surrounded by an electron cloud containing 35 electrons.

The analogous formula for magnetic fields is the Ampere's law.
To find the answer, we need to know about the Ampere's law of magnetism.
<h3>What's Ampere's law of magnetism?</h3>
Ampere's law states that the close line integral of magnetic field around a current carrying loop is directly proportional to the current enclosed within it.
<h3>What's is the mathematical expression of Ampere's law?</h3>
Mathematically, Ampere's law is
B•dl= μ₀I
Thus, we can conclude that the analogous formula for gauss law is the Ampere's law in magnetism.
