Initial launch velocity, u = 0
Acceleration, a = 300 m/s²
Duration, t = 8.0 s
The distance traveled is
h = ut + (1/2)*a*t²
= (0 m/s)*(8 s) + 0.5*(300 m/s²)*(8 s)²
= 9600 m
Answer: 9600 m
Answer: 4.64 × 10^7 mg
Explanation:
Given:
T =1299g + 45.1kg
Convert kg to g
T = 1299g + 45.1kg ×1000g/kg
T = 1299g + 45100g
T = 46399g
T= 4.64 × 10^4 g
Convert to milligram
T = 4.64 × 10^4 g × 1000mg/g
T = 4.64 × 10^7 mg
Therefore, 1299g + 45.1kg = 4.64 × 10^7 mg
Hydraulic jacks, automobile brakes and even the lift generated on airplane wings can be explained using Pascal's principle. Pascal's principle is based on the idea that fluids at rest are incompressible, allowing very large forces to be transmitted with the application of a smaller force.
<h2>Answer:</h2>
<u>The correct answer is </u><u>(A) The chemical energy in the food is converted to mechanical energy to give the body energy to move.
</u>
<h2>Explanation:</h2>
The chemical energy in food can be converted to another form of chemical energy when it is stored as glucose or fat. The chemical energy in our food can also be converted to mechanical energy in the form of muscle movement and it provides us energy to travel and move from one place to another pace. The entire energy is not converted to mechanical though, it is also converted into heat energy.
Distance traveled by car =14m
Total time taken =2sec
Speed =distance / time
=14m/2sec
speed=7 m/sec
