scoray [572]3 years ago
7 0

Answer:

1.02  m/s

Explanation:

Speed change = (final speed) - (initial speed)

Final speed = (initial speed) + (acceleration) x (time)

So Speed change = (acceleration) x (time)

(4.3 min) x (60 sec /min) = 258 seconds

Speed change = (0.0046 m/s²) x (258 seconds)

Speed change = 1.02m/s

Parallaxes of stars are sometimes measured relative to the positions of galaxies or distant objects called quasars. Why is this
Elenna [48]

Answer:

quasars are massive celestrial bodies that are far or remotely placed emitting large energy radiations.

parallax is the best way of determining distances between astronomical bodies and parallaxes of stars are measured relative to a quasar to minimise the measurement error. each observations is stimulated with the basic angle variations leading to minimum uncertainty in the results as the assumptions in the measurements are as minimal as possible.

zvonat [6]

Answer:

32.40 N

Explanation:

Acceleration due to gravity on the moon is 1.62 m/s².

W = mg

W = (20 kg) (1.62 m/s²)

W = 32.40 N

What is the maximum energy EmaxEmaxE_max stored in the capacitor at any time during the current oscillations
DanielleElmas [232]

Complete Question

An L-C circuit has an inductance of 0.350 H and a capacitance of  0.290 nF . During the current oscillations, the maximum current in the inductor is 2.00 A .

What is the maximum energy E_{max} stored in the capacitor at any time during the current oscillations?

Express your answer in joules.

Answer:

The value is   E_{max} =   0.7 J

Explanation:

From the question we are told that

   The inductance is L  =  0.350 \  H

    The capacitance is C =  0.290 \ nF =  0.290 *10^{-9 } \ F

   The current is  I  = 2 \ A

Generally the maximum energy is mathematically represented as

        E_{max} =  \frac{1}{2}  *  L  *  I^2

=>       E_{max} =  \frac{1}{2}  *   0.350  *  2^2

=>     E_{max} =   0.7 J
