Answer:
.50 M
Explanation:
5*.50=2.5 + 2*.25=.5 = 3n
6*.50= 3N
Final answer is .50M
The answer is A I believe. Hope this helps!
Complete question:
The recoil of a shotgun can be significant. Suppose a 3.6-kg shotgun is held tightly by an arm and shoulder with a combined mass of 15.0 kg. When the gun fires a projectile with a mass of 0.040 kg and a speed of 380 m/s, what is the recoil velocity of the shotgun and arm–shoulder combination?
Answer:
The recoil velocity of the shotgun and arm–shoulder combination is 1.013 m/s
Explanation:
Given;
combined mass of the shotgun and arm–shoulder, m₁ = 15 kg
mass of the projectile, m₂ = 0.04 kg
speed of the projectile, u₂ = 380 m/s
let the recoil velocity of the shotgun and arm–shoulder combination = u₁
Apply the principle of conservation of linear momentum;
m₁u₁ + m₂u₂ = 0
m₁u₁ = - m₂u₂
Therefore, the recoil velocity of the shotgun and arm–shoulder combination is 1.013 m/s
Answer:
Tides occur 2 times a day.
Explanation:
Because that's what left over after removing the moon's average gravitational pull at each different location on earth.
The meridian directly opposite the Prime one ... roughly down the middle of the Pacific Ocean ... is the meridian of <em>180° longitude, both East and West.</em>
Technically, it should also be the International Date Line, but it's not. The International Date Line has been defined with several kinked segments in it, in order to avoid having it cut through the few islands that lie along 180°.
If it were allowed to do that, there would be nations that would have two different calendar dates on the same island. Kids who live on one side and go to school on the other side would constantly be either cutting school or showing up on Saturday, and people would be missing their dental appointments on the other side. Much easier just to put a kink in the International Date Line so that whole country is on the same calendar date.
