Answer:
0.84 m
Explanation:
Given in the y direction:
Δy = 0.60 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
0.60 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 0.35 s
Given in the x direction:
v₀ = 2.4 m/s
a = 0 m/s²
t = 0.35 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.4 m/s) (0.35 s) + ½ (0 m/s²) (0.35 s)²
Δx = 0.84 m
Answer:
both experience forces or at least a force
Explanation:
it would go in the direction the other object
(second object, the one that crashed) was going
si if going right then right if left then left
plus or minus
The answer is a. Chemical energy.
Photosynthesis is a process in plants wherein light energy is converted to chemical energy, which is then stored as glucose. This is stored in the chloroplasts.
Photosynthesis is divided into two stages: the light and dark stage. In the light stage, the light energy is converted into ATP and NADPH, these are like the energy cells of the plant. After the light stage, the ATP and NADPH that were produced are used in the dark stage. The dark stage will use these energy cells to transform carbon dioxide into sugar.
What is the direction of the frictional force?
Answer:
Direction of friction is always opposite to relative motion
Explanation:
Friction always resist the relative motion of two surface so it is always opposite to the direction of relative velocity
What is the direction of the normal force?
Answer:
It is perpendicular to the contact plane
Explanation:
Normal force is the perpendicular force which is always at 90 degree with the contact surface
How does the frictional force depend on the normal force?
Answer:
![F_f = \mu F_n](https://tex.z-dn.net/?f=F_f%20%3D%20%5Cmu%20F_n)
Explanation:
Friction force is directly proportional to the normal force so we can say it is given as
![F_f = \mu F_n](https://tex.z-dn.net/?f=F_f%20%3D%20%5Cmu%20F_n)
Let the x-axis be parallel to the incline and the y-axis rise from the incline at a right angle. By Newton's second law, if there is no acceleration in the y-direction (perpendicular to the plane), what must be the magnitude of the normal force?
Answer:
![F_n = mg cos\theta](https://tex.z-dn.net/?f=F_n%20%3D%20mg%20cos%5Ctheta)
Explanation:
Normal force is equal to the component of the weight opposite to the direction of normal force
![F_n = mg cos\theta](https://tex.z-dn.net/?f=F_n%20%3D%20mg%20cos%5Ctheta)
Use Newton's second law and the x-components of the forces to find the acceleration. m/s2
Answer:
![a = gsin\theta](https://tex.z-dn.net/?f=a%20%3D%20gsin%5Ctheta)
Explanation:
As we know that
![F_{net} = ma](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20ma)
![mg sin\theta = ma](https://tex.z-dn.net/?f=mg%20sin%5Ctheta%20%3D%20ma)
![a = gsin\theta](https://tex.z-dn.net/?f=a%20%3D%20gsin%5Ctheta)
Answer:
i think the answer to this is D
