They cause an increase in temp of earths atmosphere or warming by absorbing solar energy. hope this helps
Explanation:
The given statement is absolutely true. this is because magnitude of a vector is always non negative, it can not be zero unless its a zero vector. So, in the given question, final position vector of a moving object has a smaller magnitude than the initial position vector, so, magnitude is neither zero nor negative. Hence, it has a positive magnitude.
The time of flight of the launched particle will be 2v₀ sinθ / g.
<h3>What is kinematics?</h3>
The study of motion without considering the mass and the cause of the motion.
A projectile is launched from level ground with an initial speed v₀ at an angle θ with the horizontal. If air resistance is negligible.
Then the time of flight of the launched particle will be given as,
Determine how long it requires the projectile to reach its highest point in order to calculate the flight duration. Just twice as long as the maximum altitude is the travel time.
At maximum height, 
.
The time to reach maximum height is given as
The time of flight is given as,
Substituting in 
, then we have
The time of flight of the launched particle will be 2v₀ sinθ / g.

Explanation:
Achievement is one of the psychosocial needs identified by the psychologist Henry Murray. The motivation to achieve is a need or desire to attain a certain standard of excellence. People with high achievement motivation don’t just try hard; they are also realistic in the goals they set for themselves. People with low achievement motivation set goals that are either very easy to attain or too ambitious.
