(a) The average speed from A to B would be 1.76 metre per second and the average velocity from A to B would also be 1.76 metre per second
<span>(b) The average speed from A to C would be 1.73 metre per second and the average velocity from A to C would be 0.87 metre per second</span>
Answer:4.05 s
Explanation:
Given
First stone is drop from cliff and second stone is thrown with a speed of 52.92 m/s after 2.7 s
Both hit the ground at the same time
Let h be the height of cliff and it reaches after time t
For second stone
---2
Equating 1 &2 we get
Answer:
bouyant force - the upward force on an object in a fluid
boiling point - the temperature at which a liquid becomes a gas
solubility - the ability of a substance to dissolve in another
conductivity- the ability to transfer heat or electricity
density - the amount of mass in a given volume
The maximum energy that can be transferred by the electrical generator is 2.7×10¹³ Joules.
We can use the equation of electric power and electric energy.
Electric Power: This can be defined as the ratio of the electric energy to the time of electrical equipment.
⇒ Formula
- P = E/t............... Equation 1
⇒Where:
- P = Maximum electric power
- E = Maximum electric Energy
- t = time.
make E the subject of the equation
- E = Pt................. Equation 2
From the question,
⇒ Given:
- P = 1.5×10⁹ W
- t = 5 hours = (5×60×60) seconds = 18000 seconds = 1.8×10⁴ s
⇒ Substitute these values into equation 2
- E = (1.5×10⁹)(1.8×10⁴)
- E = 2.7×10¹³ Joules.
Hence, the maximum energy that can be transferred by the electrical generator is 2.7×10¹³ Joules.
