Answer:
The correct option 50.0 m (<u>the units of the answers are wrong, they should be in meters and not in millimeters</u>).
Explanation:
From the first second we can find the acceleration of the object:
Where:
: is the final position = 2.00 m
: is the initial position = 0
: is the initial speed = 0 (starts from rest)
t: is the time = 1 s
The acceleration is:
Now, we can find the distance after 5 seconds:
Therefore, the correct answer is 50.0 m. All the options have the units in millimeters and not in meters hence, the units of the options are wrong.
I hope it helps you!
Answer:
Rs. 480.00
Explanation:
1kW = 1000W
therefore 500W = 0.5kW
20 × 24hrs = 480hrs in total.
0.5kW × 480hrs = 240kWh
if rs. 2 for 1kWh
then, 240kWh × 2 = Rs. 480.
Answer:
A) 1.5 V
B) 4.5 V
Explanation:
A) Batteries in parallel have the same voltage as an individual battery.
V = 1.5 V
B) Batteries in series have a voltage equal to the sum of the individual batteries.
V = 1.5 V + 1.5 V + 1.5 V
V = 4.5 V
Explanation:
The initial kinetic energy is
The final kinetic energy is
The work done W on the car is
The power expended P is
E= 0.6
Constant sigma is 5.6704004× 10∧ (-8)
The area is LC = 2× .8 = 1.6m∧2
to convert degrees celcious to Kelvin =303K
The equation is
P = e ? AT∧4.
Then the answer is 460 watts.
