That's a true statement ... not a question.
When the kinetic energy of an object changes, energy
may be transferred either to or from the object.
Given that,
Mass of ring = m
Mass of sphere = M
Radius = R
Distance = √8R
We need to calculate the intensity of gravitational field
Using formula of intensity
Put the value into the formula
We need to calculate the force of attraction between the ring and the sphere
Using formula of attraction force
Where, M = mass of sphere
E = intensity of gravitational field
Put the value into the formula
Hence, The force of attraction between the ring and the sphere is
Answer: a) 0.04kW = 40W
b) 0.05
Explanation:
A)
Thermal efficiency of the power cycle = Input / output
Input = 10 kW + 14,400 kJ/min = 10 kW + 14,400 kJ/(60s) = 10 kW + 14,400/60 kW.
Output = 10 kW
Thermal Efficiency = Output / Input = 10kW / 250kW = 0.04KW = 40W
B)
Maximum Thermal Efficiency of the power cycle = 1 - T1/T2
Where T1 = 285kelvin
And T2 = 300kelvin
Maximum Thermal Efficiency = 1 - T1/T2 = 1 - 285/300 = 0.05
Answer:
C) If an ice cube is placed into a boiling water, then it will melt in less than 2 minutes.
Explanation:
<span>Ans: The source Address field specifies the station that sends the frame.
The format of an Ethernet frame includes a destination address at the beginning which contains the address of the device which is sending the frame. And, the source address tells us which station the information is received from. </span>
