Answer:
Stretch in the spring = 0.1643 (Approx)
Explanation:
Given:
Mass of the sled (m) = 9 kg
Acceleration of the sled (a) = 2.10 m/s
²
Spring constant (k) = 115 N/m
Computation:
Tension force in the spring (T) = ma
Tension force in the spring (T) = 9 × 2.10
Tension force in the spring (T) = 18.9 N
Tension force in the spring = Spring constant (k) × Stretch in the spring
18.9 N = 115 N × Stretch in the spring
Stretch in the spring = 18.9 / 115
Stretch in the spring = 0.1643 (Approx)
The answer is 3+5+4 = 10+3 so then you have to add the number to the part of the equation and you will get the answer of five
Answer: yes
Explanation: Assuming a it's moving 20m/s in the west direction and slowing down at a rate of -5m/s² (deceleration), the negative sign would imply the westward direction because -5 west is the same thing as +5 east. So, the boat is moving 20m/s west direction and accelerating at 5m/s² east direction.
Other examples of these are: Cars and and tricycles.
All of the above
As it's given that
- A uniform electric field in the z direction
Means the plane it's perpendicular to it xy plane.
Hence all are correct
Shortwave radios have a higher frequency than ultraviolet light
