5.5-7=-1.5 time interval would be 5 hrs.
you then take the -1.5 ÷ 5hrs = -.3
Answer:
Explanation:
Geosynchronous orbit (GSO): Orbits with an altitude of approximately 35,786 km (22,236 mi). Such a satellite would trace an analemma (figure 8) in the sky. Geostationary orbit (GEO): A geosynchronous orbit with an inclination of zero.
Answer:
A always point toward the sun
Answer:
The magnetic force can act from a distance because of the magnetic field that is created around it. It can be defined as imaginary lines around the magnet upto which it has magnetic force.
If a piece of iron is put into the magnetic field but has a slight distance from the magnet, it will be pulled towards the magnet because it is in its magnetic field.
The south pole and the north poles of the magnet has effect on each other. Same poles repeal each other and opposite poles attract each other resulting in forming a field of attraction or repulsion.
The imaginary lines created are known as magnetic field which is responsible for the magnetic force from a distance.
Answer:
Angular acceleration,
Explanation:
It is given that,
Displacement of the rotating wheel,
Time taken, t = 2.9 s
Initial speed of the wheel,
Final speed of the wheel,
Let is the angular acceleration of the wheel. Using the third equation of kinematics to find it as :
So, the angular acceleration of the wheel is . Hence, this is the required solution.
