Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.Feb 14, 2013
The magnitude of velocity for this car is equal to 1.5 m/s.
<u>Given the following data:</u>
- Momentum of car = 3,000 kgm/s.
To calculate the magnitude of velocity for this car:
<h3>What is momentum?</h3>
In Science, momentum simply means a multiplication of the mass of an object and its velocity.
Mathematically, momentum is giving by the formula;

Making velocity the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Velocity = 1.5 m/s.

This loss of stable old ice has set up additional losses of sea ice cover each summer because the thinner younger ice is more easily melted during the recent warmer summers. Because of their dependence upon the sea ice for food, these changes can directly affect the carrying capacity of the Arctic for polar bears. Mark this as the brainliest answer please
