Obviously, for its latitude.
Do this type of thing but change it a little bit. This is a conservation of momentum problem. The initial momentum of the system (gun + bullet) is zero, as neither is moving.
There fore, after the gun is fired, the total momentum must still be zero.

The negative sign tells us that the gun travels in a direction opposite to that of the bullet.
<h2>
Answer: The Systeme international (International System of Units
)</h2>
The International System of Units (SI) is used in almost every country in the world (<em>except Burma, Liberia and the United States</em>).
This system was created in 1960 by the 11th General Conference of Weights and Measures in France and is made up of seven basic units:
-Ampere (electric current)
-Kelvin (temperature)
-Second (time)
-Meter (length)
-Kilogram (mass)
-Candela (luminous intensity)
-Mol (amount of substance) *added to the system in 1971
Plus an unlimited number of derived units from the main ones.
The molecular geometry of both F2 and HF is linear.There are only two atoms which are covalently bonded and thus, the bonding scheme with the atoms looks like this;
F --- F
H---F
So, both are linear.
Answer:
d) The image would be dimmer
Explanation:
When inverted image of an object is viewed on a screen from the side facing a converging lens, the
lens focuses the diverging, and blurred light rays from the distance object through refraction of the rays two times.Then the rays is converge by the double bending cl at a focal point behind the lens inorder for a sharper image to be be observed.
But when an opaque card is then introduced to cover only the upper half of the lens then the image becomes dimmer because of the reduction in the light intensity on the screen by 50%
