<h3><u>Answer;</u></h3>
4 waves
<h3><u>Explanation;</u></h3>
Wavelength of one wave = 0.25 meters
Length of the rope = 1 meter
Therefore;
Number of waves = Length of the rope/wavelength of one wave
= 1/0.25
= 4 waves

Answer:
A. mass
Explanation:
<u>Mass</u> determines the quantity of inertia for an object. Mass is the quantity that depends upon the inertia of an object. The inertia that an object has is directly proportional to the mass of the object.
An object that has more mass has a greater tendency as compared to the object that has less mass to resist changes in its state of motion.
Answer:
t = 20 s
Explanation:
145 m = 9 m/s × t – 35m
We can obtain the value of t in seconds by doing the following:
145 m = 9 m/s × t – 35m
Add 35 m to both side as shown below:
145 m + 35 m = 9 m/s × t – 35m + 35 m
180 m = 9 m/s × t
Divide both side by 9 m/s
t = 180 m / 9 m/s
t = 20 s
Therefore, the value of t is 20 seconds.
