Answer: small barrel gun
Explanation:
It is noted that short barrel guns have a higher muzzle velocity for bullets compared to longer barrel guns.
Acceleration is determined by the change in velocity with respect to time.
For short barrel guns, the bullet reaches its muzzle velocity more quickly, leading to greater acceleration than that of bullets from long barrel guns.
Answer:
0.0016 cm
Explanation:
= The thermal expansion coefficient for brass = 
= The thermal expansion coefficient for glass = 
= Temperature change = 
= Original radius = 4 cm
The change in radius is described by
The radius difference between the lid and the jar
The gap measures 0.0016 cm or 0.000016 m
x₂ = 16 g m₂ / k. The spring's behavior adheres to Hooke's law, expressed as F = k x. For equilibrium illustrated in Newton's diagram, F - W = 0 and k x₁ = m₁ g, leading to k = g m₁ / x₁. In an elevator moving upward with acceleration, the relation adjusts to F - W = m a, which gives F = m (g + a). Compression becomes K x₂ = 4 m (g + 3g), simplifying to x₂ = 4m / k (4g) and ultimately x₂ = 16m2 / k g.
2×10⁻⁷ Ωm. From the problem, we have R = 4ρL/πd². Hence, solving for ρ, we get ρ = Rπd²/4L. When both the length and diameter are doubled while keeping the resistance fixed, the new resistivity is derived as ρ' = 2(1×10⁻⁷), resulting in ρ' = 2×10⁻⁷ Ωm.
