Answer:
The y-component of the normal force is 45.74 N.
Explanation:
Given that,
Mass of the crate, m = 5 kg
Angle with hill, 
We need to find the y component of the normal force. We know that the y component of the normal force is given by :

So, the y-component of the normal force is 45.74 N. Hence, this is the required solution.
Answer:
1. Convection (Moving Water)
2. Radiation (Sunlight)
3. Conduction (Direct Contact)
4. Convection or Radiation (Most Likely Convection) (Moving Air/Sunlight)
5. Convection (Moving Air)
6. Radiation (Feeling Heat)
Explanation:
See Above
Answer:
The two possible frequencies of the other player's note are 437.3 Hz and 442.7 Hz
Explanation:
Given Data
f₁=440 Hz
fₐ=2.7 beats per seconds
The beat frequency is equal to the difference in the frequencies of the two original waves:
So
f
=|(f₁±fₐ)|
First to Solve for (-) Sign we get
f=|(440-2.7)|
f=437.3 Hz
Now for Solve for (+) Sign we get
f=|(440+2.7)|
f=442.7 Hz
The two possible frequencies of the other player's note are 437.3 Hz and 442.7 Hz
