<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:
20g
Explanation:
Given parameters:
Quantity of heat = 240calories
Initial temperature = 80°C
Final temperature = 68°C
Unknown:
Mass of water = ?
Solution;
To solve this problem, we use the expression:
Q = m c (t₂ - t₁)
Q is the quantity of heat
m is the mass
c is the specific heat = 1 cal/g°C
t₂ is the final temperature
t₁ is the initial temperature
Insert the parameters and solve;
Change in temperature is an absolute value
240 = m x 1 x (68 - 80)
m = 20g
