a) Imagine that it's raining towards Ox, so x-component is 2
b) Rain towards Oy: 4.
c) V=(2, 4)
What you see rising from the road ... and call "heat waves" ...
are rising currents of air. The air that's been heated by
contact with the hot asphalt rises. (Why ? By being heated,
it becomes less dense than the other air around it, and the
buoyant force of being a less dense substance in a more dense
fluid makes it rise (float) ).
If we want to paint a complete picture, we can find all three
types of heat transfer going on here:
1). The air getting heated by direct contact with the hot road ==> conduction
2). The hot air rising through the cooler air around it ==> convection
3). How the road got so hot in the first place ==> radiation, from the sun
<span>the mountains that are formed between two large faults are known as : d. fault-block mountains
Fault-block mountains are commonly consist of several large blocks of rocks which length could spread for hundreds of kilometers.
These mountains were created by the tectonic process from the Earth's crust</span>
A fuel injection system that does not use a sensor to measure the amount (or mass) of air entering the engine is usually called speed density type of system.
<h3>What is speed density fuel injection system?</h3>
Speed density fuel injection system is a fuel delivery method.
This system relies on a combination of sensor and an intake air temperature sensor to measure the amount (or mass) of air entering the engine.
Thus, a fuel injection system that does not use a sensor to measure the amount (or mass) of air entering the engine is usually called speed density type of system.

Answer:
false here is why :)
Explanation:
Regular, moderate-intensity physical activity reduces the risk of developing coronary heart disease and can reduce the likelihood of dying from heart disease.
hope this helped.
