Answer:
a cold air mass and a warm air mass merge together
The spring formula:
Force = - (spring constant) · (distance stretched or squashed)
6 N = - (spring constant) · (33 cm)
= - (0.33 m) · (spring constant)
Spring constant = - (6 N) / (0.33 m)
= - 18.18 N/meter .
The negative signs means that the spring always wants to go in the
opposite direction from where you forced it, and return to its relaxed
length. If you stretch it, it tries to get shorter, and if you compress it,
it tries to get longer.
<span>Birds which famous for performing a ritualized mating dance are: The Grebes
Grebes most commonly live near a fresh water source.
They conducted this ritual because When two Grebes with opposite sex dances near each other, they will release some sort of pheromones that make them attracted to one another. </span>
Answer:
10kg
Explanation:
Weight is "how much does gravity drag this down".
Mass is "how much matter is there here".
The relation is:
where is the weight, is the mass and is the gravitational acceleration (roughly equal to 10N/kg on Earth).
From the task we know that:
So let's input it into the relation:
