Answer: They create antibodies.
Answer a kind of radiation including visible light, radio waves,gamma rays,and x-rays,in which electric and magnetic fields vary simultaneously
Explanation:
One thing you should notice. It is kind of weird. Ke has no direction so that fact that it has velocities associated with it does not matter. It becomes a scaler (something measured by amount alone).
General Formula
Ke = 1/2 m v^2
Formula for this problem
Ke = 1/2 m (v2)^2 - 1/2 m (v1)^2
Givens
m = 1200 kg
v2 = 100 km/hr = 100 km/h * [1 hour / 3600 sec] * [1000 m/ 1km] = 27.8 m/s
v1 = 50 km / hr = 13.9 m/s
Substitution and work.
================
delta Ke = 1/2 1200 (27.8)^2 - 1/2 1200 (13.9)^2
delta Ke = 463704 - 115926
delta Ke = 34778 Joules
delta Ke = 34.8 kJ
The change is 34.8 kJ which means that the vehicle gains 34.8 kJ
Answer:
Explanation:
The diffraction pattern is given as
Sinθ = mλ/ω
Where m=1,2,3,4....
Now, when m=1
Sinθ = λ/ω
Then,
ω = λ/Sinθ
The width of the central bright fringe is given as
y=2Ltanθ. From trigonometric
Then,
θ=arctan(y/2L)
Given that,
y=0.052m
L=0.55m
θ=arctan(0.052/2×0.55)
θ=arctan(0.0473)
θ=2.71°
Substituting this into
ω = λ/Sinθ
Since λ=544nm=544×10^-9m
Then,
ω = 544×10^-9/Si.2.71
ω = 1.15×10^-5m.
