Given data in the problem :-
- Acceleration (a) = 4.0 m/s^2
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 34 m/s
- Distance travelled by aircraft (S) = ?
From Newton's Laws of Motion we know that ,
v = u + at [t = Time taken by aircraft to cover the distance]
⇒ 34 = 0 + 4t
⇒ t = 34/4 s
∴ t = 8.5 s
From Newton's Laws of Motion we also know that ,
S = u.t + 1/2a.t^2
⇒ S = 0×8.5 + 1/2 × 4 × (8.5)^2 m
∴ S = 144.50 m
Thus the distance travelled by the aircraft while accelerating is 144.50 meter .
Answer:
Explanation:
First, define 
( electromotive force )-is the unit electric charge imparted by an energy source. In this case the generator.
The peak emf is:
=
Substituting 
and the value for peaf 
gives:
Total length=
=
=
Hence, wire's length is 171.43m
I think the best way to answer to this kind of question because some of the elements are missing specially the mass of the book is just states the variables and assigned as the mass of an object. So the initial velocity of an object starts at zero and increase rapidly by 9.8 m/s^2 because it is due to gravity
Answer:
D.
Explanation:
Newton's Law of Gravitation states that:
If the masses of each object is small, then 
would be very small, making the gravitational force between the two objects hard to detect - as it itself would be very small.
Given Information:
Potential difference = V = 450 V
Current = I = 0.80 A
time = t = 1 ms = 0.001 s
Required Information:
(a) Energy = E = ?
(b) Total charge = q = ?
Answer:
(a) Energy = 0.36 J
(b) Total charge = 8x10⁻⁴ C
Explanation:
(a) What is the energy delivered by this pulse
The energy is given by
E = V*I*t
Where V is the potential difference, I is the current flowing and t is the time.
E = 450*0.80*0.001
E = 0.36 J
(b) what is the the total charge that flows?
We know the current is the rate of charge
I = q/t
q = I*t
q = 0.8*0.001
q = 0.0008
q = 8x10⁻⁴ C
