Answer:
Explanation:
Given that
F=2x³
Work is given as
The range of x is from x=0 to x=D
W=-∫f(x)dx
Then,
W=-∫2x³dx from x=0 to x=D
W=- 2x⁴/4 from x=0 to x=D
W=-2(D⁴/4-0/4)
W=-D⁴/2
W=1/2D⁴
The correct answer is F
120 km/3 hours. 40/1=?/3 1x3=3 hours so 40x3=120 km
Answer:
The amount of charge on a single proton is equal to the amount of charge possessed by a single electron. A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.

Answer:
6.8 s
Explanation:
Let's say the west end of the field is position 0 m and the east end of the field is position 250 m.
The position of kitten A is:
x = 0 + 25 t
And the position of kitten B is:
x = 250 - 12 t
The kittens collide when they have the same position:
25 t = 250 - 12 t
37 t = 250
t ≈ 6.8 s
I think the statement is false. It is not only the battery life that would distinguish one type of mobile computer from another. There are other aspects that would characterize every mobile computer. It could be the brand, the size, the operating system, the hardware specifications like the RAM, processor and the video card. Every mobile computer would vary depending on the brand, model and intended use.
