In case of an object sitting at rest on another base, there are two equal and opposite forces – Normal force and the gravity.
Answer: Option A
<u>Explanation:
</u>
When an object is placed at rest position on another object, there is a force exerted by the surfaces of the two contact objects. This force is denoted as Normal Force.
When an object such as a box is placed on a shelf, its surface exerts a contact force on the base of the shelf- The Normal force directed upward. Meanwhile, the gravity stays at its action and tries to pull the box towards itself.
Both of these forces however are equal and opposite and therefore, there is zero net force on the box. That's why it remains at rest, holding on Newton's third law.
It would be alto. I hope that is one of your answers.
Answer:
a) Species change over time; some traits become more common, others less. This process of change is driven by natural selection. The traits that become more common are the ones that are “adaptive” or “increase fitness” (that is, a creature's chances of living longer and producing more offspring)
Explanation:
because it is
Answer:
32°
Explanation:
From the diagrammatic representation of the question,
Point A is the pilot point of view from the airplane
Point C is the foot of the first tree
Point D is the foot of the second tree
Line AB is the height of the airplane from the ground level.
Line CD is the distance between the two trees
Considering ΔABC,
tan 33°
BC = 5000 / tan 33°
BC = 7,699.41 feet
BD = BC + CD
BD = 7,699.41 + 300
BD = 7,999.41 feet
Considering ΔABD,
tan θ
tan θ
tan θ = 0.6250
θ = tan⁻¹ 0.6250
θ = 32°
