Momentum = mass × velocity
P = mv
P = 0.08 × 14
= 1.12 kgms^-1

With Uranus at an average distance of 2.88 billion kilometres from the Sun and Neptune at an average distance of 4.5 billion kilometres it would be very easy to point out which of the gas giants is the coldest, but if you were you were to say that Neptune was the coldest, you’d be wrong.<span>Given that we expect planets further from the Sun to be colder than those closer, this does make Neptune and Uranus quite a mysterious pair. Uranus and Neptune are brimming with volatiles such as water, methane and ammonia and due to their composition in comparison to Jupiter and Saturn, which are comprised mainly of hydrogen and helium, are labelled the ice giants. Scientists have measured how hot Uranus and Neptune should be and have found that Uranus is very cold and very dim</span>
No, the pins do not have the same velocity when they are knocked down.
Explanation:
Speed is a scalar quantity while Velocity is a vector quantity.
A scalar quantity has one component that is the magnitude of that quantity. A vector quantity on the other hand has two components. First is the magnitude of the quantity and the second component is the direction.
Velocity is a vector quantity and it has two components; the magnitude which is the same as the speed and the direction.
In the given situation, the pins when knocked down have same speed but the direction is different. If one component of a vector quantity changes, the quantity is said to be different. We cannot say that two bodies moving with same speed in different directions have same velocities.

I think the correct answer from the choices listed above is option D. The force most responsible for holding the nucleus of an atom together is the strong nuclear force of attraction between particles in the nucleus. It <span>is also </span>responsible<span> for binding the quarks and gluons into protons and neutrons. </span>
Answer:
In a truss bridge, two long - usually straight members known as chords - form the top and bottom; they are connected by a web of vertical posts and diagonals. The bridge is supported at the ends by abutments and sometimes in the middle by piers.
