Answer: buzzer.

The working principle of a buzzer is the conversion of electrical energy to sound energy.

The switch just cuts or permits the flow of current, the motor convertes electrical or other kind of energy into mechanical energy, a bulb converts electrical energy into light and a battery converts chemical energy into electrical energy.

The density of blood is 1.05 kg/m3, find the mass of a bag of blood for a transfusion, if the volume is 1.5 m3.
hoa [83]

(1.5 m^3) • (1.05 kg/m^3) = 1.575 kg.  That's quite a bag you've got there !  1 m^3 is like 264 gallons of blood.  Hope the poor patient survives the transfusion. Also, the actual density of blood is around 1.05 g/cm^3, or 1050 kg/m^3. The blood they're giving the guy in this question is about 18% less dense than the AIR in his hospital room, and they're pumping 264 gallons of it into him. Maybe THAT'S his whole problem.

A potential difference of 18 V is applied to a resistor whose resistance is 240 Ω . What is the current that flows through the r
leonid [27]

Answer:

0.075A

Explanation:

V = IR

where V - voltage, I - current, R - resistance

Hence, 18 = I * 240

I = 18/240

I = 0.075A

For a birthday gift, you and some friends take a hot-air balloon ride. One friend is late, so the balloon floats a couple of fee
LuckyWell [14K]

Answer:60 kg

Explanation:

Given

mass of people =1140 kg

and balloon is neutral when 1140 kg is loaded in the balloon .

when another person come balloon started descending at the rate of 0.49 m/s^2

For initial condition

F_b=mg

F_b=1140\times 9.8=11.172 KN

For second case

(1140+m)\times 9.8-F_b=(1140+m)\times 0.49

(1140+m)\times (9.8-0.49)=11.172 \times 10^3

1140+m=1200

m=60 kg
