She covered 25 meters in 10 seconds.
Her SPEED is (25 m) / (10 s) = 2.5 m/s .
We don't have any way to describe her velocity, because we don't know what DIRECTION she ran.
Answer:
Explanation:
To give a solution to the exercise, it is necessary to consider the concepts related to magnetic flux and Faraday's law of induction. Faraday's law states that the voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as an edge changes over time.
It is represented under the equation,
Where,
is the induced electromotive force
N = Number of loops
= Time
= Magnetic Flux
For definition the change in magnetic flux is:
Where,
B= Magnetic field
Substituting at the first equation we have
Our values are given by,
N = 1 turn
r = 1.6mm
Replacing,
<em>Therefore the magnitud of the induced emf around a horizontal circle of tissue is </em>
That transition produces one of the lines in the "Lyman series". A photon is emitted with a wavelength of 102.57 nm, in the ultraviolet.
Answer:
Explanation:
initial velocity, u = 0
final velocity, v = 60 mph = 26.8 m/s
time t = 10 s
Let a be the acceleration and s be he distance traveled.
Use first equation of motion
v = u + a t
26.8 = 0 + a x 10
a = 2.68 m/s
Use second equation of motion
s = ut + 1/2 at²
s = 0 + 0.5 x 2.68 x 10 x 10
s = 134 m
As, 1 m = 3.28 ft
So, s = 134 x 3.28 ft
s = 439.6 ft
