Answer:100 K
Explanation:
We know that Freezing Point of water is at 1 atm
Converting it to Kelvin we get 273.15 K
Boiling Point of water is
converting it to Kelvin we get 373.15 K
Difference in the number we get =373.15-273.15=100 K
Temperature difference is independent of degree and will remain same for Celsius and Kelvin
Answer:
Option D: Four times the original speed.
Explanation:
A centripetal force accelerates a body by changing the direction of the body's velocity without changing the body's speed.
The speed(v) is therefore constant, thereby making the magnitudes of the of the acceleration and the force constant.
The formula used to calculate the Centripetal force is given below:
where F represents the Centripetal force, m represents the mass of the moving body, v represents the speed or velocity at which the body is moving and r represents the radius.
Making the speed the subject of the formula:
Therefore, when the radius (r) is changed to 4r, i.e r = 4r
speed(v) becomes
After comparing, the difference between the speeds is Four times the original speed.
