Answer:
= 591.45 T/s
Explanation:
i = induced current in the loop = 0.367 A
R = Resistance of the loop = 117 Ω
E = Induced voltage
Induced voltage is given as
E = i R
E = (0.367) (117)
E = 42.939 volts
= rate of change of magnetic field
A = area of loop = 7.26 x 10⁻² m²
Induced emf is given as
= 591.45 T/s
Explanation:
x = 3.00 – 2.00t + 3.00,
Distance of object at 2 second,
x (t=2) = 3(4) - 2(2) +3
x (t=2) = 12-4 +3
x (t=2) = 11 m
Distance of object at 3 second,
x (t=3) = 3(9) - 2(3) +3
x (t=2) = 27 - 6 + 3
x (t=2) = 24 m
a) the average speed between t = 2.00 s and t = 3.00 s,
Average speed =
Average speed =
Average speed =
Average speed =
Average speed = 11.66
b) the instantaneous speed at t = 2.00 s and t = 3.00 s,
Instantaneous speed =
Instantaneous speed(v) = 6t - 2
Instantaneous speed,v(t=2 to t=3) = 18-2-12+2
Instantaneous speed, v = 6
c) the average acceleration between t = 2.00 s and t = 3.00 s
average acceleration =
average acceleration =
average acceleration = 11.66
d) the instantaneous acceleration at t = 2.00 s and t = 3.00 s
instantaneous acceleration =
instantaneous acceleration =6
instantaneous acceleration = 6
e) for x =0
0 = 3.00 – 2.00t + 3.00
a = 3, b=-2, c=3
t=
t=
t=
general solution of this equation gives imaginary value. Hence, the given object is not at rest.
Answer:
Explanation:
Given
Child falls a height of
Applying conservation of energy we can write
Loss in Potential energy=Gain in kinetic energy
Thus child reaches a velocity of 4.42 m/s
