They are rotating because the earth never stops rotating.
Answer:
the speed of the satellite is 12,880.53 km/h
Explanation:
Given;
radius of the circular orbit, r = 24,600 km
time taken to revolve around Earth, t = 12 hours
The circumference of the satellite is calculated as;
L = 2πr
L = 2π x 24,600 km
L = 49,200π km
L = 154,566.36 km
The speed of the satellite;
v = L/t
v = 154,566.36 / 12
v = 12,880.53 km/h
Therefore, the speed of the satellite is 12,880.53 km/h
1.Iron atoms tend to form regions, clusters. These are what become magnetized and then affected by magnetic fields
Answer 2
.When two magnets are brought near each other, like poles repel; opposite poles attract.
2) When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.
Answer:
224236.76 W
Explanation:
Power: This can be defined as the rate of change of energy. The S.I unit of power is Watt(W).
From the question,
P = E/t ......................... Equation 1
Where P = power, E = Energy or work, t = time.
But,
E = Wt×d.................. Equation 2
Where Wt = Total weight of the passengers, d = distance.
Substitute equation 2 into equation 1
P = (Wt×d)/t.............. Equation 3
Given: Wt = 590×150 =88500 N, d = 244 m, t = 96.3 s.
Substitute into equation 3
P = (88500×244)/96.3
P = 224236.76 W
Two things that aren't involved in speed: -- the straight-line distance between the start- and end- points. -- the direction from start-point to end-point.
