Answer:small barrel gun
Explanation:
Given
Muzzle velocity of bullet is greater in short barrel gun as compared to larger barrel gun
acceleration is given by change in velocity with respect to time
In case of short barrel bullet time taken by bullet to reach its muzzle velocity is less therefore acceleration of small barrel bullet is more compared to long barrel bullet.
A dark-colored (igneous rock,) commonly extrusive from volcanic eruptions and composed primarily of the minerals of calcic plagioclase and pyroxene, and sometimes olivine. Basalt is the fine-grained equivalent of gabbro.
Answer:
The fractional Intensity 
= 0.0146
Given:
wavelength of the light, 
slit and screen separation difference, D = 130 cm = 1.3 m
distance of the point from the center of the principal maximum, y = 4.10 mm = 0.041 m
slit width, d = 0.420 mm = 
Solution:
To calculate the fractional intensity, we use the given formula:
(1)
For very small angle:
(2)
where
Using eqn (2):
Now, using eqn (1):
If the planet earth has no land masses, the idealized zonal
precipitation pattern would likely have regions that are wet in the equator and
there will be more of mid-latitudes if the earth has no land masses at all and
it does not exist.
Answer: The scientist should revise the question to address a gap in knowledge.
Explanation:
The scientist should revise the question to address a gap in knowledge. is the correct option this is because of the fact that on revising the question as well as observing the findings of the other scientists the scientist may realize the fact that what other variable can be used for the purpose of the experiment and what other factor can be included in framing the question. This will help in evolution of the same findings by many researchers. This will add up more knowledge in the overall research procedure.
