The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.
As the speed is a scalar quantity as it has the only magnitude in it. Therefore, the average speed is also stated as a scalar quantity.
Hence, the correct answer is (B)
Answer:
The appropriate answer is "0.9152 seconds".
Explanation:
The given values are:
Maximum speed,
v = 8.85 m/s
Acceleration,
u = 9.67 m/s²
Now,
⇒ 
By putting the values, we get
⇒ 
⇒ 
⇒
Dark matter is called dark because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect or emit electromagnetic radiation, and is therefore difficult to detect.
