Answer:
(a). The velocity is 0.099 m/s.
(b). The position is 19.75 m.
Explanation:
Given that,
The deceleration is
We need to calculate the velocity at t = 25 s
The acceleration is the first derivative of velocity of the particle.
On integrating
....(I)
At t = 0, v = 10 m/s
Put the value of C in equation (I)
The velocity is 0.099 m/s.
(b). We need to calculate the position at t = 25 sec
The velocity is the first derivative of position of the particle.
On integrating
At t = 0, s = 15 m
Put the value in the equation
The position is 19.75 m.
Hence, (a). The velocity is 0.099 m/s.
(b). The position is 19.75 m.
Answer:
1) The energy released during nuclear fission or fusion, especially when used to generate electricity is called nuclear energy.
2) It is not renewable because it is an element that has no way whatsoever to regenerate or replicate itself, nor gets created by any natural terrestrial means, neither makes itself available by arriving from outer space (like sunlight). There is a limited amount of it available on the Earth, and every bit you use is a bit you’ll never have available again (as Uranium atoms get destroyed by the fission process).

Answer:
4A
Explanation:
Current is charge per time. So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.
2 × 2A = 4A
I dont know if it right but <span>Use a universal power adapter. This is perhaps the most obvious solution to your battery woes. Readily found at most retail outlets that carry electronics, a universal power adapter can range anywhere in price from $30 to $100 or more. The adapter comes with multiple tips, one of which will likely fit your laptop’s charging port. When plugged in, the adapter will not only power your laptop, but will charge its battery as well.</span>
