Answer:
B) No.
Explanation:
Okay,so,
this is equation is y=mx +b
mx represents the slope
and b represents the y-intercept
in order to figure this out you need to plot the y-intercept first
that makes its (0,-6) because the 6 is negative in the equation
4x is also equal to 4/1 since we dont know what x is
we have to do rise over run for this
you go up 4 spots on the y intercept from -6 because 4 is positive
then you go to the right 1 time because 1 is positive.
this leaves you at (1,-2)
so, (2,2) is NOT a solution
The sugar cube experiment in the laboratory gives us a good approximation of the amount of energy that can be derived from the sugar cube because the amount of energy is neither created or destroyed, it is just converted to another form. If the energy from the sugar cube is converted to other form in the lab then, it is possible that same amount of energy will be derived.
force=mass x acceleration
acceleration= velocity/time
given that m=2300kg
v = 15m/s
t = 0.54s
f= 2300 x 15/0.54
f =2300×27.777
f=63888.89
The amount of energy required to raise the temperature of one gram of water by one celsius degree is called a calorie.
<h3>How can you define calorie?</h3>
In physics, we can define it as a unit of measurement that defines the amount of energy to raise the temperature of 1 gram of water by 1°C. Each material has its unique calorie, however by definition we use water as it is the lowest of all the elements.
Normally, calorimetry is directly linked with the thermal capacity that an element has to contain heat.

Answer: The distance between the charges is r=0.44m
Explanation
Step one
Using the formula
F = (k q1*q2) /r²
F = electric force
k = Coulomb constant
q1, q2 = charges
r = distance of separation
Step two
Given data
F=179N
q1 and q2=+68.0 µC and +56.0 µC
k=8.98755 × 10^9 N
r=?
Step three
Inputting our values we have
179=8.9875×10^9(68*10^-6*56*10^-6)/r²
179=(8.9875*10^9*3.8*10^-9)r²
179=34.15/r²
Make r subject of formula we have
r²=34.15/179
r²=0.190
r= √0.190
r=0.44m
Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
