Answer:4s^-1
Explanation:Tangential Acceleration=v^2/r=(20)²/100=400/100
Answer:
(a) 17634.24 Ω
(b) 0.0068 A
Explanation:
(a)
The formula for inductive inductance is given as
X' = 2πFL................... Equation 1
Where X' = inductive reactance, F = frequency, L = inductance
Given: F = 60 Hz, L = 46.8 H, π = 3.14
Substitute into equation 1
X' = 2(3.14)(60)(46.8)
X' = 17634.24 Ω
(b)
From Ohm's law,
Vrms = X'Irms
Where Vrms = Rms Voltage, Irms = rms Current.
make Irms the subject of the equation
Irms = Vrms/X'...................... Equation 2
Given: Vrms = 120 V, X' = 17634.24 Ω
Substitute into equation 2
Irms = 120/17634.24
Irms = 0.0068 A
Answer: Energy from the core travels by radiation through the radiative
zone, then by convection through the convection zone.
Explanation:
You have traveled 390 km. In order to find your answer all you have to do is multiply your speed which is 130 km/h by 3 hrs. That's my friend is how you get your answer! Have a great day!
Answer:

Explanation:
Momentum is the product of mass and velocity.

The mass of the truck is 2,000 kilograms and the velocity is 35 meters per second.

Substitute the values into the formula and multiply.

The truck's momentum is <u>70,000 kilograms meters per second.</u>
