The answer is b
300,000 km
Answer:
17.0 m s^-1
Explanation:
This question can be answered using suvat equations: (I'm assuming you know what these are)
s = 34.0 m
u = 0
v = ?
a = N/A
t = 4.00s
The only suvat equation that doesn't contain "a" is s = (u+v/2)t.
Make "v" the subject so v = 2s/t.
v = (2 x 34.0)/4.00 = 17 m/s
Answer:
20000 pounds
Explanation:
Generally 1 gallon of fuel burnt gives of 20 pounds of CO₂
Difference in the gallons of fuel burnt
The 20 mpg car burns 1000 gallons of fuel more than the 30 mpg car
The amount of CO₂ would be
The fewer pounds that the 30 mpg car would release is 20000 pounds
Answer:
hypothesis, sorry if I'm wrong
The answer is 323 K.
<u>Explanation:</u>
The Celsius temperature scale is equal to - 273.15.
One kelvin is equal to the change of thermodynamic temperature that results in a change of thermal energy kT by 1.380649 * 10^−23 J.
Convert degrees Celsius to kelvins with this simple formula:
kelvins = [degree C] + 273.15
The formula to convert Celsius to kelvins is degree C + 273.15.
50 degree celsius = 50 + 273.15
= 323.15 = 323 K.
