R=62.5/5=12.5
So the answer is 12.5 kilometers per hour
I'm sure is true hopefully.
Answer:
three fourths, because the angles are complementary
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Answer:
20.0mL
Step-by-step explanation:
The general gas formula is expressed as;
P1V1/T1 = P2V2/T2
P1 and P2 are the initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
T1 and T2 are the initial and final temperature respectively
If the temperature and pressure are both doubled, then;
P2 = 2P1 and T2 = 2T1
Given
V1 = 20.0mL
Required
New volume V2
Substitute the given parameters into the formula above as shown;
P1V1/T1 = P2V2/T2
20P1/T1 = (2P1)V2/(2T1)
20 = 2V2/2
20 = V2
Hence the new volume is also 20.0mL
