Answer:
v = 16 m/s
Explanation:
It is given that,
Acceleration of a particle along x -axis is 
At t = 0s, its velocity is 6 m/s
We need to find the velocity at t = 4 s
It means that the initial velocity of the particle is 6 m/s
Let v is the velocity at t = 4 s
So,
v = u + at
So, the velocity at t = 4 s is 16 m/s.
The units used to measure speed and velocity are as follows: m/s, Km/h, and mph.
That depends on which angle you picked first, because that determines
which angles "the other two" are.
If you picked the right angle (90°) first, before you asked the question,
then the other two are acute angles, and they're also complementary

Explanation:
Momentum is defined as the product of mass by velocity, and can be calculated by means of the following expression.
where:
P = Momentum [kg*m/s]
m = mass = 10 [g] = 0.01 [kg]
v = velocity = 400 [m/s]
i)
![P=0.01*400\\P=4[kg*m/s]](https://tex.z-dn.net/?f=P%3D0.01%2A400%5C%5CP%3D4%5Bkg%2Am%2Fs%5D)
ii)
The momentum of the gun is equal to zero, because it does not move before being fired, the weapon only moves after having fired the weapon.
iii)
Since the momentum is conserved before and after the shot, the same momentum given to the bullet is equal to the momentum received by the gun.
![v_{recoil}=P/m\\v_{recoil}= 4/2\\v_{recoil}=2[m/s]](https://tex.z-dn.net/?f=v_%7Brecoil%7D%3DP%2Fm%5C%5Cv_%7Brecoil%7D%3D%204%2F2%5C%5Cv_%7Brecoil%7D%3D2%5Bm%2Fs%5D)
Answer:
Despite being such prominent feature on our planet, much of the mid-ocean ridge system remains a mystery. While we have mapped about half of the global mid-ocean ridge in high resolution, less than one percent of the mid-ocean ridge has been explored in detail using submersibles or remotely operated vehicles. so therefore we do not have enough information about them to know what will happen
Explanation:
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The speed of spreading affects the shape of a ridge slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.
