Answer:
Magnets are employed to generate electricity.
Explanation:
Magnets' characteristics are employed to generate electricity. Electrons are pulled and pushed by moving magnetic fields. When you move a magnet around a coil of wire, or a coil of wire around a magnet, the electrons in the wire are pushed out and an electrical current is created.
Question:
The question is incomplete. The mass and radius of the orbit was not added. Find below the remaining part of the question and the answer.
Rank from largest to smallest.
A) m=200 kg and L= 5000m
B) m=400 kg and L=2500m
C)m=100kg and L=2500m
D)m=100kg and L=10000m
E)m=800kg and L=5000m
F)m=300kg and L=7500m
Answer:
Fe > Ff > Fa = Fb = Fd > Fc
4*10^6 N > 2.25*10^6 > 1 *10^6 N = 1 *10^6 N = 1 *10^6 N > 0.25*10^6 N
Explanation:
The force experienced by the satellite is given by the formula;
Fc = kmL
where;
k = constant = 4π²/T²
m = mass of satellite
L = radius of orbit
Since, all the satellites complete the circular orbit in the same amount of time. The constant k does not affect the force value.
A) The force acting on satellite A from their rocket is given as follows:
Fa = kmL
Fa = 200 * 5000
= 1 *10^6 N
B) The force acting on satellite B from their rocket is given as follows:
Fb = kmL
=400 *2500
= 1*10^6 N
C) The force acting on satellite C from their rocket is given as follows:
Fc = kmL
= 100 *2500
= 0.25*10^6 N
D) The force acting on satellite D from their rocket is given as follows:
Fd = kmL
= 100 *10000
= 1*10^6 N
E) The force acting on satellite E from their rocket is given as follows:
Fe = kmL
= 800 *5000
= 4*10^6 N
F) The force acting on satellite F from their rocket is given as follows:
Ff = kmL
= 300 *7500
= 2.25*10^6 N
The ranking is given as:
Fe > Ff > Fa = Fb = Fd > Fc
4*10^6 N > 2.25*10^6 > 1 *10^6 N = 1 *10^6 N = 1 *10^6 N > 0.25*10^6 N
Explanation:
An object's weight depends on the pull of the gravitating object but the object'<u>s mass is independent of the gravity. </u>
If the velocity of the chair is constant, then the net force acting on it is zero.
The force you exert to keep it going is equal and opposite to the force of friction.
Answer:
The area of the liquid surface does not affect the pressure.
