The piston in the cylinder head of a locomotive has a stroke (twice the amplitude) of 1.0 m. If the piston moves with simple harmonic motion with an angular frequency of 200 rad/min, what is its maximum speed?
Angular frequency of the piston, ω = 200 rad/ min
Stroke = 1.0 m
Amplitude, A = 1.0 / 2
= 0.5 m
The maximum speed (vmax) of the piston is given by the relation:
Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10-2 cm, mounted coaxially within a cylindrical anode with a radius of 0.5580 cm. The potential difference between the anode and cathode is 275 V. An electron leaves the surface of the cathode with zero initial speed v(initial) = 0). Find its speed v(final) when it strikes the anode.
A proton follows the path shown in (Figure 1). Its initial speed is v0 = 1.4 x 10^6 m/s.
Part A What is the proton's speed as it passes through point P? Express your answer to two significant figures and include the appropriate units.
A company has cash of $100 million, accounts receivable of $600 million, current assets of $1.2 billion, accounts payable of $400 million, and current liabilities of $900 million. What is its acid-test (quick) ratio?
A proton is released from rest at the positive plate of a parallel-plate capacitor. It crosses the capacitor and reaches the negative plate with a speed of 45000 m/s.
What will be the final speed of an electron released from rest at the negative plate?
