In this case, the movement is uniformly delayed (the final
rapidity is less than the initial rapidity), therefore, the value of the
acceleration will be negative.
1. The following equation is used:
a = (Vf-Vo)/ t
a: acceleration (m/s2)
Vf: final rapidity (m/s)
Vo: initial rapidity (m/s)
t: time (s)
2. Substituting the values in the equation:
a = (5 m/s- 27 m/s)/6.87 s
3. The car's acceleration is:
a= -3.20 m/ s<span>^2</span>
d. lower frequencies and low energy.
Explanation:
Microwaves and infrared waves are lower frequencies and lower energy waves.
They are both non-ionizing radiation.
- Microwaves and infrared waves are both electromagnetic waves.
- They do not require a material medium to be propagated in nature.
- They have little energy because the have very low frequency.
- They also have very long wavelengths.

I think it is 7 in the first row and 6 in the second. I am very sorry if wrong :D
1. In construction. When constructing roads, building
2. In Engineering, when engineering we use physics such as calculations.
3. At home
4. In industries, industries use chemicals and so on.
5. In tailoring, we use the knowledge of physics like when sowing.
6. In carpentry, we use calculations.
7. In Hospitals, we use physics we balancing
8. In Sites, we use energy.
