(d) is increasing its velocity by 2.0 m/s every second.
An acceleration of 2 m/s² means that the object is is increasing its velocity by 2.0 m/s every second.
<h3>What is an acceleration?</h3>
The rate at which an object's velocity changes over a predetermined period of time is referred to as its acceleration. Acceleration is mathematically defined as an object's change in velocity divided by the amount of time it took for that change to occur.
The positive sign of the acceleration denotes a change in velocity that is positive and growing, whereas the negative sign denotes a change in velocity that is decreasing.
Consequently, an acceleration of 2 m/s² indicates that the object's velocity is increasing by 2 m/s every second.

The speed of the disturbances in The waves should remain the same since they are all electromagnetic waves (C=3*10^8m/s)
Answer:
20kph
Explanation:
Since she travels 100kpm in 5 hours and 100 divided by 5 is 20 she would travel 20km in one hour
Answer:
The Tension in the cable is 392.3N. The vertical reaction at the hinge (fixed end) is 850.3N.
The tension in the cable was calculated using the principles of moments which states that the total sum of the clockwise moments is equal to the total sum of anticlockwise moments on a system in equilibrium.
Explanation:
Sum of Clockwise moments = Sum of anticlockwise moments
900×1 + 200×3 + 90×6 = T×Sin120 × 6
900 + 600 + 540 = 5.20T
T = 2040/5.20 = 392.3N
Summing vertical forces
R + Tsin120 = 900 +200+90
R + 392.3sin120 = 1190
R + 339.7 = 1190
R = 1190 - 339.7
R = 850.3N
