Answer:
Explanation:
Change in magnetic flux = no of turns x area of coil x change in magnetic field .
= 139 x π R² x ( 92.1 - 57.7 ) x 10⁻³
= 139 x 3.14 x 2.13²X 10⁻⁴ x 34.4 x 10⁻³
= 6.8118 x 10⁻³ Weber
rate of change of flux = change of flux / time
= 6.8118 x 10⁻³ / .175
= 38.925 mV .
Answer:
f =63.64Hz
Explanation:
The equation of the transverse periodic wave
y = 0.005 sin(20.0x + 2ft)
From the equation we can deduce that
Amplitude A = 0.005
Wave number K = 20
Angular frequency w = 2πf
We are asked to find the frequency (f)
the formular for the wave number is given as K = 2π / lambda
Lambda = 2π/ K
Lamda is the wavelength
= 2 × 3.142 /20
= 0.3142m
The velocity of the wave is expressed as v = frequency × lamba (wavelength)
Frequency = velocity / wavelength
f = 20/ 0.3142
f = 63.65Hz
Answer:
the distance from the location of the center of gravity to the location of the center o mass for this system is 1.13m
Explanation:
Given that
m₁=4.4kg
x₁=+1.1m
m₂=3.7kg
x₂=+0.80m
m₃=2.9kg
x₃=+1.6m
The position of the center of mass is
Xcm = [m₁x₁ +m₂x₂ +m₃x₃]/(m₁+m₂+m₃)
= [(4.40kg)(1.1 m)+(3.70 kg)(0.80 m)+(2.90 kg)(1.60 m)]/(4.4 kg + 3.70 kg+2.90 kg)
= 1.13 m
The position of the center of gravity is 1.13m
Therefore, the distance from the location of the center of gravity to the location of the center o mass for this system is 1.13m
Yes, but it's a null vector .So,no vector can have a component at right angle to itself unless it is a zero vector.
Answer:
It would be static discharge and conduction
Explanation:
The conduction of static energy is pulled throughout the clothes and left over static electricity is what causes the spark.
