Answer:
-40 °C
Key Takeaways: When Does Fahrenheit Equal Celsius? Celsius and Fahrenheit are two temperature scales. The Fahrenheit and Celsius scales have one point at which they intersect. They are equal at -40 °C and -40 °F.
There’s 10mm in a cm: 22mm
Answer:
The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.
Answer:
1 I am not sure but I tried
Answer:
Explanation:
Let initial mass of the moving car is m it is moving with the speed of v m/s.
Thus, Kinetic energy of the car is given by,
Initial Kinetic energy =
Now the velocity of moving car is changed to 3v where as its mass remains the same.
Thus, Kinetic energy of the car is given by,
Final Kinetic energy =
Final Kinetic energy =
The change in kinetic energy is given by,
Change in kinetic energy
= Final kinetic energy - initial kinetic energy
= -
=
Thus, when the speed of a moving car is tripled, kinetic energy is
