The law of conservation of momentum states that, if left alone, the total momentum of two interacting objects that make up a system remains the same.
Answer:
Displacement by cyclist is zero.
Explanation:
In the given question bicyclist is travelling in a rectangular track having P , Q and R edges.
The bicyclist starts from P and travel through Q and R and returned to P again.
We need to find its displacement.
We know displacement of a body is its difference between its initial position to final position.
Here in the given question the bicyclist returns to P again.
Therefore, total displacement by bicyclist is zero.
Hence, this is the required solution.
Answer: #.37 times greater
Explanation: Volume of a sphere is: V = ·π·r³
Since it is given the diameter of the basketball and the softball, their ratios are r₁ = 3in and r₂ = 2in, in which index 1 represents the basketball and index 2, the softball.
Calculating the volume of basketball:
V₁ = . 3.14 . 3³
V₁ = 113.04 in³
Calculating the volume of softball:
V₂ = . 3.14 . 2³
V₂ = 33.5 in³
Comparing one volume with the other:
= = 3.37
We have that V₁ = 3.37V₂
This means the volume of a basketball is 3.37 times greater than the volume of a softball.
Answer: heyyy want to talk your question
Explanation:
Answer:
3.6 × 10¹² nanoseconds
Explanation:
Hour is the unit of time. Seconds is the SI unit of time.
Hour and seconds are related as:
1 hour = 60 minutes
1 minute = 60 seconds
So,
1 hour = 60 ×60 seconds = 3600 seconds
Thus,
3600 seconds are in one hour
Also,
1 sec = 10⁹ nanoseconds
Thus,
3600 sec = 3600 × 10⁹ nanoseconds = 3.6 × 10¹² nanoseconds
Thus,
<u>3.6 × 10¹² nanoseconds are in one hour.</u>
