Answer: 
Explanation:
Given
Mass of the elevator is 
Time period of ascension 
cruising speed 
Distance moved by elevator during this time
Suppose Elevator starts from rest
Distance moved
Gain in Potential Energy is
Average power during this period is
The formula for Celsius to Fahrenheit is T(°F)<span> = </span>T(°C)<span> × 1.8 + 32
Your answer would be 68 degrees Fahrenheit</span>
The correct answer is
<span>c the friction force from the road
In fact, the friction force between the road and the tires of the car acts as centripetal force, keeping the car in circular motion.</span>
Answer:
Mg will replace Ag in a compound
Explanation:
A single replacement reaction is driven by the position of ions on the activity series.
As a rule of thumb, the position of metal ions on the activity series determines their reactivity.
Metal ions that are above another are more reactive and they will displace those that are lower.
Generally, activity increases as we go up the group.
Mg ions are higher than Ag ions on the series so, Mg will displace Ag from a solution.
a hypothesis is given to explain a phenomena which has not been explained earlier.
it can proved by an experiment if that experiment gets the other results regarding that particular phenomena in agreement with that being predicted by the hypothesis and if result doesnt match the prediction then the hypothesis is again totally discarded at times.
