Explanation:
Answer:
Power rating on the blender = 3809.52 Watts
Explanation:
We have expression for power equal to ratio of work and time,
Energy used by blender = Work done by electricity = 0.8 MJ = 
Time of using blender = 3.5 minutes = 210 seconds
So power of blender = 800000/210 = 3809.52 Watts
Power rating on the blender = 3809.52 Watts
Answer:
The final pressure of the whole system is 34.80 atm.
Explanation:
Given that,
Volume = 45.0 ml
Volume of first bulb = 77.0 mL
Pressure = 8.89 atm
Volume of second bulb = 250 mL
Pressure = 2.82 atm
Volume of third bulb = 21.0 mL
Pressure = 8.42 atm
We need to calculate the final pressure of the whole system
Using formula of pressure

Where,
= pressure of first bulb
= pressure of second bulb
= pressure of third bulb
= initial pressure of tube
= Volume of first bulb
=Volume of second bulb
= Volume of third bulb
= Initial volume of tube
Put the value into the formula



Hence, The final pressure of the whole system is 34.80 atm.
V=d*t
Since d=75km=75000m
t=1.5h=3600*1.5= 5400s
=>V=75000*5400
=405000000m/s=4.05*10^8m/s
