Answer:
The pressure of the tire will be 4.19 atm
Explanation:
The ideal gas equation is:
p0 * V0 / T0 = p1 * V1 / T1
Since V0 = V1 because the volume of the tire doesn't change
p0 / T0 = p1 / T1
p1 = p0 * T1 / T0
We need absolute temperatures for this equation
16 C = 289 K
45 C = 318 K
Now we replace the values:
p1 = 3.71 * 318 / 289 = 4.19 atm
Answer:
14
Explanation:
The total no of protons and neutrons in an atomic nucleus is called mass number, nucleon number or atomic mass number. It is denoted by A.
In this problem, we need to find the nucleon number of carbon-14 i.e. mass number of carbon -14. 14 with carbon shows its mass number.
Hence, the nucleon no of carbon-14 is 14.
U=1/2kx2

Answer:
O Column 1 should be titled "Time," and Column 2 shouldbe titled "Velocity,"
O Column 1 should be titled "Velocity," and Column 2 should be titled "Time."
O Column 1 should be titled "Time," and Column 2 should be titled "Acceleration."
O Column 1 should be titled "Acceleration," and Column 2 should be titled "Time."
Answer:
Explanation:
Let's use the kinematic equation
s = ut + ½at²
Where
s = distance fallen
u = initial velocity
t = time taken
a = acceleration
Here the hammer is dropped so a = g = gravitational acceleration
u = 0 because the hammer is dropped.
So by substituting you get,
1000 = 0 + ½×10×t²
t² = 200
t = 14.14 s
