<span>Heat comes from stove flame to the sauce pan by radiation through infrared energy, heat conducts the metal of the sauce pan; Convection brings cool water to the hot surface at the bottom of the hot sauce pan until all or most of the water is hot enough to boil.</span>
Answer : Option D) 90°N and 90°S
Explanation : The latitudes which are given in the options are the angle to be measured in the direction of north and south respectively taking equator as the central line.
When it is 90°N and 90°S it means it forms an right angle and faces towards north and south respectively with respect to the equator, so there are high chances of pointing towards the Arctic and Antarctic regions respectively; therefore giving greater probability of finding glaciers.
1575 N
Explanation:
Step 1:
Let us consider that 350 J of energy is spent by that person to push a couch to 4.5 m from its initial position.
Let F be the force required and E be the energy spent and D be the distance traveled by the couch from its initial state.
In Physics, Work done = Force / Displaced distance
Step 2:
Let the work done be 350 J and Distance be 4.5 m
Then Force exerted = 
The power delivered by the elevator is 34496 W.
<h3>What is power?</h3>
Power is the rate at which energy is used up.
To calculate the power delivered by the elevator, we use the formula below.
Formula:
- P = mgh/t.............. Equation 1
Where:
- P = Power delivered by the elevator
- m = Total mass on the elevator
- g = acceleration due to gravity
- h = Height
From the question,
Given:
- m = 1.1×10³ kg
- h = 40 m
- t = 12.5 s
- g = 9.8 m/s²
Substitute these values into equation 1
- P = 1.1×10³×40×9.8/12.5
- P = 34496 W.
Hence, the power delivered by the elevator is 34496 W.
