Newton's second law states that (Force is mass times acceleration). Out of the given options, “a 10 kg ball thrown with a 50 Newton force”, an example have the greatest acceleration.
<u>Explanation:
</u>
To do the calculation, we already have the formula given derived from Newton’s second law of motion. To know the acceleration, we can simply modify the formula as,
For the 10kg ball threw in 50N, we have mass = 10 kg and Force = 50 N
Acceleration =
Similarly for 1 kg ball threw in 0.5N, substituting the values, we get
,
Acceleration =
For launching 50kg student by catapult of 100N,
acceleration =
For accelerating 500 kg car in 1000N engine,
acceleration =
Answer:
B. 832 m/s
Explanation:
(1/2) (0.015) v^2 = (3/2) (1.5) (8.31) (278)
0.0075 v^2 = 5197.905
v^2 = 693054
v = 832.49
Answer:
the speed of the nerve impulse in miles per hour is 201.59 mi/hr
Explanation:
Given;
the speed of the nerve impulse, v = 90.1 m/s
To convert this speed in meters per second to miles per hour, we use the following method;
1,609 meter = 1 mile
3,600 s = 1 hour
Therefore, the speed of the nerve impulse in miles per hour is 201.59 mi/hr
Answer:
<u>Aluminium</u>
Explanation:
aluminum is the perfect heat shield material offering excellent protection against excessive exhaust system heat. Ultra-high-temperature ceramics,(UHTC), such as zirconium diboride (ZrB2) and hafnium diboride (HfB2) may be of choice.
