Answer:
Explanation:
To calculate the red shift you use the following formula:
\tetha: angle between the observer and the motion of the body
v: speed of the body
c: speed of light
for motion with angle 90° (transversal motion):
- A red dwarf moving away from Earth at 39.1 km/s :
- A yellow dwarf moving transversely at 15.1 km/s (angle = 90°):
- A red giant moving towards Earth at 23.3 km/s (angle = 0°):
- A blue dwarf moving away from Earth at 25.9 km/s
- A red dwarf moving transversely at 14.1 km/s
Answer:
Time taken to reach your destination will be 10hours
Explanation:
Recall the formula for Speed;
speed=Total distance/Total time taken
Speed=2km/h
Total distance=20km
Time taken=x
let x be the unknown time taken
Input each values into the formula;
2=20/x
Making x subject of the equation
x=20/2
x=10
Total time taken =10hours.
Answer:
Yes, the carters are always facing the Earth as the moon orbits.
Explanation:
Yes, you can. Remember that in electrophysics, opposite charges attract. Since there is a stand of rotation, it allows the rod with both ends having opposite charges to rotate. Now, if you place the unknown charge near the set-up, it could turn clockwise or counterclockwise. When the set-up turns such that the negative end is approaching the unknown charge, that charge must be positive. Otherwise, the unknown charge is negative.
