Answer:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
Step-by-step explanation:
We know that the temperature of the freezer is never greater than -2°C. Yesterday the temperature was -10°C but it increased at a steady rate of 1.5°C per hour. We calculate how long in hours and minutes did the temperature increase inside the freezer.
We conclude that the difference in temperature is 8°C.
We get:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
Answer:
d) F2 = -F1.
Step-by-step explanation:
According to Coulomb's law of forces on electrostatic charges, the force of attraction is proportional to the product of their charges, and inversely proportional to the square of their distance apart.
What this law means is that both particles will experience an equal amount of force on them, due to the presence of the other particle. This force is not just as a result of their individual charges, but as a result of the product of their charges. Also, the force is a vector quantity that must have a direction alongside its magnitude, and the force on the two particles will always act in opposite direction, be it repulsive or attractive.
Answer:
5x + 15 = -5x - 15
10x = -30
x = -3
y = 5(-3) + 15 = -15 + 15 = 0
(-3,0)
