The seat belt is applying a force in the opposite direction.
Explanation:
It varies with altitude, but at sea level, it's 9.8 m/s².
Answer:
Option C. The chloroplasts contain chlorophyll pigments requires for photosynthesis.
The focal length of the converging lens based on the arrow placed 3 centimeters to the left and the imaged formed 3 cm to the right is 1.5 cm.
<h3>
Focal length of the converging lens</h3>
The focal length of the converging lens is determined by applying the following converging lens formula.
1/f = 1/v + 1/u
where;
- v is the image distance = 3 cm
- u is the object distance = 3 cm
- f is the focal length = ?
1/f = 1/3 + 1/3
1/f = 2/3
f = 3/2
f = 1.5 cm
Thus, the focal length of the converging lens is 1.5 cm.

Answer:
38.7 units
Explanation:
a = 3.00 t² – 4.20 t
Integrate to find velocity as a function of time.
v = ∫ a dt
v = ∫ (3.00 t² – 4.20 t) dt
v = 1.00 t³ – 2.10 t² + C
The object starts at rest, so at t = 0, v = 0.
0 = 1.00 (0)³ – 2.10 (0)² + C
0 = C
v = 1.00 t³ – 2.10 t²
Integrate to get position as a function of time.
x = ∫ v dt
x = ∫ (1.00 t³ – 2.10 t²) dt
x = 0.250 t⁴ – 0.700 t³ + C
Find the difference in positions between t = 4.50 and t = 0.
Δx = [0.250 (4.50)⁴ – 0.700 (4.50)³ + C] – [0.250 (0)⁴ – 0.700 (0)³ + C]
Δx = 0.250 (4.50)⁴ – 0.700 (4.50)³
Δx = 38.7
The object moves 38.7 units.
