Answer:
Therefore, beats per minute did increase for 36.
Step-by-step explanation:
48: 2/3=x:1
48=2/3 × x
x=3/2×48
x=72
81:3/4=x:1
81=x×3/4
x=4/3×81
x=108
Therefore, beats per minute did increase for 36.

Step-by-step explanation:
Answer:
y = 3
Step-by-step explanation:
Subtract 11 from both sides to get:
2y = 6
Then divide both sides by 2 to isolate y:
y = 3
Answer:
The recoil velocity of the gun is
and is pointing in opposite direction to the velocity of the bullet.
Step-by-step explanation:
Use conservation of linear momentum, which states that the momentum of the bullet (product of the bullet's mass times its speed) should equal in absolute value the momentum of the recoiling gun (its mass times its recoil velocity).
We also write the mass of the bullet in the same units as the mass of the gun (for example kilograms). Mass of the bullet = 0.010 kg
In mathematical terms, we have:
