5 is the tripoid stand
Thanks have a bangtastic day
2. Motivation is the internal desire
<u>Answers</u>
same distance from the mirror as the object
same size
lateral inversion
<u>Explanation</u>
The image formed by a plane mirror is formed at equal distance from the mirror as the object is.
The size of the image is the same as the size of the object.
The image is laterally inverted. This means that, when a person lifts his right hand, his or her image will raise it's left hand.
Answer: 1.4mi/hr²
Explanation:
Blank 1: We know that acceleration is the change in velocity/change in time
Using this, we know that the acceleration will be: (50-15)/25 = 1.4
Blank 2: mi/hr²
As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases
<h3>Static frictional force</h3>
Since the static frictional force between the block and the plane is given by F = μN where
- μ = coefficient of static friction and
- N = normal force on plane = component of weight of block perpendicular to the plane = Wcosθ where
- W = weight of block and
- θ = angle of inclined plane
Now, F = μN
F = μWcosθ
Since μ and W are constant, we see that
F ∝ cosθ and cosθ ∝ θ
So, F ∝ θ
Since the static frictional force is directly proportional to the angle the plane makes with the horizontal, when the angle the plane makes with the horizontal is increased, the static friction between the block and the plane increases.
So, As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases
