B- Predict the damages due to an earthquake
Answer:
Yes they have gotten better overtime
Explanation:
The elephant has more inertia than the dog so it takes more force to change the motion of the elephant.
Answer:
The answer to your question is Power = 0.98 W or 9.8 x 10⁻⁴ kW
Explanation:
Data
Power = ?
mass = 100 g = 0.1 kg
distance = 1 m
gravity = 9.8 m/s²
Formula
Power = Work / time
Process
1.- Calculate the Work
Work = Force x distance
Force = mass x gravity
Work = mass x gravity x distance
Work = (0.1 kg)(9,8)(1)
Work = 0.98 J
2.- Calculate the power
Power = 0.98 J / 1 h
Power = 0.98 W or 9.8 x 10⁻⁴ kW
Answer : The pressure at this new altitude is, 364.2 mmHg
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 760 mmHg
= final pressure = ?
= initial volume = 62.3 L
= final volume = 130 L
Now put all the given values in the above equation, we get:
Thus, the pressure at this new altitude is, 364.2 mmHg
