Answer:
The magnitude of the vector A is <u>51 m.</u>
Explanation:
Given:
The horizontal component of a vector A is given as:
The vertical component of a vector A is given as:
Now, we know that, a vector A can be resolved into two mutually perpendicular components; one along the x axis and the other along the y axis. The magnitude of the vector A can be written as the square root of the sum of the squares of each component.
Therefore, the magnitude of vector A is given as:
Now, plug in 44.4 for , 25.1 for and solve for the magnitude of A. This gives,
Therefore, the magnitude of the vector A is 51 m.
Answer:
Option A
Incandescent
Explanation:
While low pressure sodium light bulb produces the highest lumens per watt, it's incandescent light bulb that produces the lowest lumens per watt. It's important to note that incandescent lights operate at the same wattage as fluorescent lights to give out same amount of light but they produce the lowest lumens per watt compared to fluorescent lights.
Answer:
1. s
2. m
3. start m/s
4. end m/s
5. m/s^2
Explanation:
1. t is the suffix for the time and it is related to seconds [s]
2. d is the suffix for distance and it is related to meters [m]
3. Vi is the suffix for the initial velocity and it is related to meters per second [m/s]
4. Vf is the suffix for the final velocity and it is related to meters per second [m/s]
5. a is the suffix for the acceleration and it is related to meters per squared second [m/s^2]

Answer:
x₂ = 16 g m₂ / k
Explanation:
The spring in all cases must comply with Hooke's law
F = k x
Newton's diagram for equilibrium has
F - W = 0
k x₁ = m₁ g
k = g m₁ / x₁
When the elevator moves you have a clarification
F-W = m a
F = m (g + a)
Compression is
K x₂ =4 m (g + 3g)
x₂ = 4m / k (4g)
x₂ = 16m2 / k g
