Rina8888 [55]

Density formula is:
D = m / V
Volume of the matchbox car:
V = 46 ml - 41 ml = 5 ml = 0.005 l = 0.005 dm³
D = 10 g / 0.005 dm³
D = 2000 g / dm³ = 2 kg / dm³ = 2 × 10 ^(-3) kg/m³

A boat sounds a fog horn on a day when both the sea water and the air temperature are 25.0° C. The speed of sound in sea water i

Yanka [14]

Answer:

C) 2.24 s

Explanation:

Speed of sound in air at 25 degree = 346 m /s

Speed of sound in sea water = 1533 m/s

Time taken by sound to reach dolphin

= 1000 / 1533 = 0.6523 s

Time taken by sound to reach boatman

1000/ 346

= 2.89 s

Difference

= 2.89 - .6523

= 2.24 s

A load consists of a 70-Ω resistor in parallel with a 90-μF capacitor. If the load is connected to a voltage source vs(t) = 160c

Dimas [21]

Answer:

Power delivered by the source will be 182.912 watt

Explanation:

We have given a load is consist of a resistor of 70 ohm in parallel with $90\mu F$ capacitance

Voltage source is given $v_s(t)=160cos(2000t)$

So maximum value of voltage source is 160 volt

So rms value $v_{r}=\frac{v_m}{\sqrt{2}}=\frac{160}{1.414}=113.154volt$

We know that average power delivered by the source will be equal to average power absorbed by the resistor

So power absorbed by the resistor $P=\frac{v_r^2}{R}=\frac{113.154^2}{70}=182.912watt$

So power delivered by the source will be 182.912 watt
