Answer:
Therefore,
We can use Computer to surf internet for 5.7 hours.
Explanation:
Given:
For Clothes Dryer,
Current, I = 14 A
Voltage, V = 240 V
Time, t = 33 min = 33 × 60 = 1980 s
For Computer,
Current, I = 2.7 A
Voltage, V = 120 V
To Find:
Time, t = ? For Computer to surf with the Energy of Clothes Dryer,
Solution:
According to Joule's Law, Energy in joules for voltage "V" and Current "I" for time "t" second is given as,
For Clothes Dryer
Substituting the values we get
Now for Computer we have E = 6652.8 kJ, then time will be
Again we have,
Substituting the values we get
Time in Minutes,
Time in hours again we have to divide minutes by 60
Therefore,
We can use Computer to surf internet for 5.7 hours.
Answer:
no
Explanation:
i don,t think so the averge of the car speed is faster
The average net force exerted is 36000 N.
<u>Explanation</u>:
According to Newton's 2nd law of motion,
The net force acting upon the object is the product of mass and acceleration of an object.
Force = ma
where m represents the mass,
a represents the acceleration.
Acceleration = (change in speed) / (change in time)
Acceleration = (45 m/s) / (7 sec) = (45 / 7) m/s²
Force = (5,600 kg) x (45 /7 m/s²)
Force = (800 x 45) Newtons
Force = 36000 Newtons.
Don’t trust the people that give you these file things to click on it’s a scam!
That's true.
Magnets attract some metals such as iron, nickel, etc.
Hope this helps~
