Multiply 25 * 8 = 200
So the cheetah has gone 200 miles in 25 seconds
The correct answer is D. the star is getting farther away.
When the light has red-shifted, it shows that everything is moving away from a certain point. This is known as the Doppler effect and proves the Big Bang (which would be the center point that everything is moving away from). Just as a 'for your information', blue shift is when the star is moving towards us.
Hope I helped :)
Answer:
Explanation:
N = 65
Area, A = 0.1 x 0.2 = 0.02 m^2
R = 10 ohm
ω = 29.5 rad/s
B = 1 T
(a) at t = 0
e = N x B x A x ω
e = 65 x 1 x 0.02 x 29.5
e = 38.35 V
(b) The maximum rate of change of magnetic flux is equal to the maximum value of induced emf.
Ф = 38.35 Wb/s
(c) e = NBAω Sinωt
e = 65 x 1 x 0.02 x 29.5 x Sin (29.5 x 0.05)
e = 38.174 V
(d) Maximum torque
τ = M B Sin 90
τ = N i A B
τ = N e A B / R
τ = 65 x 38.35 x 0.02 x 1 / 10
τ = 5 Nm
Answer:
Technician B is correct
Explanation:
Charging systems works on the principle of magnetism. Charging system uses electromagnetic induction to generate electrical energy.
Electromagnetic principles states that voltage will be produced when there is a motion between conductor and the magnetic field.
The material that transmits most light is d) clear glass.
Explanation:
Depending on whether objects can transmit light or not, they can be classified into three types:
- Opaque: an object opaque does not transmit light at all (light cannot pass through an opaque object). Examples of opaque objects are metals
- Translucent: translucent objects allow light to pass partially through them. Examples of translucent objects are fluids
- Transparent: transparent objects allow light to pass through them. An example of transparent objects is clear glass
In this problem, we have the following objects:
- Umbrella: it is opaque, light does not pass through it
- Blanket: it is opaque, light does not pass through it
- Mirror: It is opaque, since it reflects light (light does not pass through it)
- Clear glass: it is a transparent object
Therefore, the material that transmits most light is d) clear glass.
