Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
Explanation:
Answer:
1570 V
Explanation:
N = 100
diameter = 2 m
radius = 1 m
B = 5 tesla
initailly the angle between the area vector of the coil and the magnetic field is zero and then the angle becomes 180 degree.
t = 2 s
Let Φ be the initial magnetic flux.
Φ = B A Cos 0 = 5 x 3.14 x 1 x 1 x 1 = 15.7 Wb
Let Φ' be the final magnetic flux
Φ' = B A Cos 180 = - 5 x 3,14 x 1 x 1 x 1 = - 15.7 Wb
According to the law of electromagnetic induction, the induced emf developed is equal to the rate of change of magnetic flux linked with the coil.


newton 1st law: w no external force, a body will stay at rest or in constant uniform motion.
a motor raises the car up the tower. cuz it moves w/ constant vel, there is no external force: the motor force is the same n in opposity direction as the gravity force on car.
Yes everything is made of cells because without cells our being can't stay together.
