Makovka662 [10]2 years ago

4 0

Answer:

Explanation:

work done = change in kinetic energy, assuming there are no energy losses.

work done = 1/2 × m × change in v^2

= 1/2 × 2.2 × ( 26^2 - 0^2)

= 1/2 × 2.2 × 676

= 743.6 joules

A violin has a string of length

Shtirlitz [24]

Answer:

1.9kHz

Explanation:

Given data

wavelength $\lambda= 0.32m$

velocity $v= 622 m/s$

We know that

$v= f* \lambda\\\\f= v/ \lambda$

substitute

$f= 622/ 0.32\\\\f= 1943.75\\\\f= 1.9kHz$

Hence the frequency is 1.9kHz

A series RCL circuit consists of a 50 Ω resistor, 500 Ω capacitor, and a 500 Ω inductor. What is the angle of impedance?

lbvjy [14]

Answer:

Zero

Explanation:

here, the inductive reactance and the capacitive reactance is same, so this is the condition for resonance.

In the condition for resonance,

the circuit and the voltage in the circuit is in the same phase and the impedance of the circuit is minimum which is equal to the resistance of the circuit.

The phase angle is given by

$tan\phi =\frac{X_{L}-X_{C}}{R}$

Which statement is true about an object that sinks in water?

bogdanovich [222]

It is about density. The less dense object will tend to float when put into the water. For example, oil is denser than water so the result of the mixture would make oil float. Sinking objects would only mean that it has an equal or greater mass than water.
