The answer would be, "1/560 seconds".
Answer:
Nuclear energy is that released by dividing the nuclei of heavy atoms (also called under the name Nuclear Fission)
Explanation:
In this process, a large amount of heat is generated that can be used to obtain mechanical energy, which is used to generate electrical energy.
Nuclear energy is a sustainable source of energy having a low impact on the environment.
Answer:
Correct answer: 11. Total distance d = 200m ; 12. Vav = 3.63m/s ;
13. Total displacement Dt = 0m ; 14. V₂(10s-15s) = 0 m/s ;
15. V₃(15s-40s) = 4 m/s ; 16. V₁(0s-10s) = 6 m/s > V₄(40s-55s) = 2.67 m/s
Explanation:
The whole movement can be divided into four stages.
In the first stage the subject moves 60m in a positive direction for 10s,
in the other it is stationary for 5s, in the third it moves 100m in the opposite (negative) direction for 25s and in the fourth in the positive 40m for 15s.
11. Total distance = 60 + 0 + 100 + 40 = 200m
12. The formula for calculating the average speed (velocity) is
Vav = (S₁ + S₂ + S₃ + S₄) / (t₁ + t₂ + t₃ + t₄)
Vav = (60 + 0 + 100 + 40)/ (10 + 5 + 25 + 15) = 200/55 = 3.63 m/s
13. The movement started from the origin and ended at the origin
Total displacement is zero meters.
14. The speed between 10s and 15s is zero, because he did not move.
15. V₃ = S₃/t₃ = 100/25 = 4 m/s
16. V₁ = S₁/t₁ = 60/10 = 6 m/s and V₄ = S₄/t₄ = 40/15 = 2.67 m/s
V₁ > V₄

Answer:
A) max = Eo = 375 V/m, B) B = 125 10⁻⁸ T
, C) f = 9.50 101⁴ Hz, D) λ = 3.158 10⁻⁷ m, E) T = 1.05 10⁻¹⁵ s
, F) invisible for humans G) v = c = 3 10⁸ m/s
Explanation:
The expression given for the electric field is
E = 375 cos (1.99 107x + 5.97 105t)
The general formula for the electric field of a transverse traveler is
E = Eo cos (kx-wt)
Where k is the wave number and w the angular velocity
A) The amplitudes as electric is
Emax = Eo = 375 V / m
B) the electric and magnetic field are related
E / B = c
B = E / c
B = 375/3 108
B = 125 10⁻⁸ T
C) angular velocity and frequency is related
.w = 2π f
f = w / 2π
f = 5.97 10¹⁵ / 2π
f = 9.50 101⁴ Hz
D) the speed of light has the formula
c = λ f
λ = c / f
λ = 3 10⁸ / 9.50 10¹⁴
λ = 3.158 10⁻⁷ m
E) The period
T = 1 / f
T = 1 / 9.5 10¹⁴
T = 1.05 10⁻¹⁵ s
F) let's reduce the wavelength nm
λ = 3.158 10⁻⁷ m (10⁹nm / 1m)
λ = 3.158 10²nm = 315.3 nm
The visible radiation range is between 400nm and 700nm. This radiation is ultraviolet and is invisible humans
G) All electromagnetic radiation has a speed at the speed of light (c)
v = c = 3 10⁸ m/s
Answer:
A
Explanation:
Ionic bonds work when a metal gives an electron to a nonmetal and this difference in charge is how they bond.
