If you're looking for distance, you have to multiply the time and speed.
0.75 × 45 = 33.75
The rabbit hopped 33.75 m.
Choice-B is the true one.
To solve the problem it is necessary to apply the concepts related to Byle's Law and Avogadro's Law.
The ideal gas equation would help us find the final solution to the problem, defined by

Where,
T= Temperature of the gas
R = Universal as constant
n = number of moles
V = Volume
P = Pressure
For our case we have that the mass of Zn is 2.2g in moles would be
[/tex]

We know that 1 mole of hydrogen gas is proceed by 1 mole of zinc and the result is
, then Hydrogen can produce the same quantity,

Applying the previous equation we have that



Therefore the volume of hydrogen gas is collected is 0.829L
Answer and Explanation:
distance will be 2×3.14 (pie)×r
displacement will be 2r (diameter)
the motion is uniform circular motion as the object is moving in a circular path with uniform motion
