Answer:
It is easier for sound waves to go through solids than through liquids because the molecules are closer together and more tightly bonded in solids.
Explanation:
The temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a calorimeter can be calculated using the following expression:
E = mc∆T
Where;
- E = energy in joules
- m = mass
- c = specific heat capacity = 4.18J/g°C
- ∆T = change in temperature
400 = 10 × 4.18 × ∆T
400 = 41.8∆T
∆T = 400/41.8
∆T = 9.57°C
Therefore, the temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.

Answer
Susan can process wind speed data from different regions.
Explanation
A Doppler radar is used in weather forecasting in measuring the direction and speed of objects such as drops of precipitation. It determines if the movement occurring in the atmosphere is horizontally towards or way from the radar. Susan can obtain velocity data about objects at a distance which might be water droplets thus be able to predict a coming weather
