Answer:
Explanation:
B = Magnetic field =
r = Radius of rim = 16 m
t = Time = 90 seconds
A = Area of rim =
EMF is given by
The magnitude of the induced emf between the hub and the rim is .
Answer:
weight =m x g =2kg × 10m/s 2 = 20N
<h3>Formulas:</h3>
weight = m × gravity
=unit for weight is newtons
Mass=weight ÷ gravity
= unit for mass is kilograms
Gravity=weight ÷ mass
=unit for gravity is 10m/sec 2
Voltage = Current (I) × Resistance (R)
V = 10 × 28.5 = 285v
The speed of light: 299,782,458 m / s
The speed of sound: 340.29 m / s
Light is faster
B is the correct hdjdjdjd
