Answer:
E = 1440 kJ
Explanation:
It is given that,
Power of a cooker oven is 800 W
Voltage at which it is operated is 230 V
Time, t = 30 minutes = 1800 seconds
We need to find the electrical energy used by the cooker oven. The product of power and time is equal to the energy consumed. So,
So, electrical energy of 1440 kJ is consumed by the cooker oven.
The two forces should be equal therefore:
2.10 * Fa = Fa + 2 * F * cos 18
simplifying the right side:
2.10 * Fa = Fa + 1.902 * F
1.10 Fa = 1.902 F
<span>F / Fa = 0.578</span>
No thats false. If your trying to say is true that people BELIEVED that then yes its true people believed it but if your talking about that question then its false
let's use first equation of motion to solve this ;
Velocity after 30 seconds = 170 m/s
Answer:0.45ohms
Explanation:
Let R be there equivalent resistance
1/R=1/r+1/r+1/r
1/R=1/5+1/1+1/1
1/R=1/5+2
1/R=(1+10)/5
1/R=11/5
Cross multiplying we get
11R=5
Divide both sides by 11
11R ➗ 11=5 ➗ 11
R=0.45ohms
