the velocity of the air is94.25V kg/s
Calculation :
Assuming velocity of air through spherical shell = V m/s
then flux = ρ *π **V kg/s
=1.2 *π **V = 94.25V kg/s
Rate of change of distance. Rate of change of displacement. The velocity of a moving object can never be negative.
Velocity is the directional velocity of a moving object as an indicator of the observed rate of change of position from a given reference frame.
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) versus change in time (Δt), given by the formula v = Δs/Δt.

Answer:
Velocity = 94.85m/s
Explanation:
<u>Given the following data ;</u>
Height = 1200m
Vertical distance = 1050m
To find the time, we would use the second equation of motion;
Substituting into the equation, we have;
t = 11.07 secs
To find the velocity;
Mathematically, velocity is given by the equation;
Substituting into the above equation;
Velocity = 94.85m/s
Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.

180° is the phase angle. An AC source is linked in series with a resistor, an inductor, and a capacitor. Inductive reactance rises with frequency because an alternating current has a time-averaged rate of change that is proportional to frequency.
Impedance of RLC series circuit
2= P²R² + (XL-X₁) ²
Here & 4 tan² (x₁=X₂) $ R +1 180° tan (XL R tan 180° = XL-X C R XL-XC R ..
XL-XC R X₁-X ₁ = 0 XL = Xc 2 = √√√ R² + 0² 2 2 = R
Resonance is the condition in question here. When induction occurs as well as capacitive reactances equal are equivalent but cancel due to the fact that they have degrees of phase separation. During resonance, Impedance is very low.

Answer:
Temperature is a measure of the average energy of molecular motion in a substance. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was in increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased.
Absolute zero is the lowest temperature in Kelvin which all motion stops. Absolute zero is called 0 Kelvin (0 K), and it is equivalent to –273.15°C or –459.67°F.
