Explanation:
Answer:8.28 km
Explanation:
Given
First it drifts 2.5 km
Secondly it drifts 4.70 km
After that it drifted along east direction 5.1 km
After that it drifts 7.2 km
After that it drifts 2.8 km
=+
for direction
south of east
To solve this problem it is necessary to apply the concept related to root mean square velocity, which can be expressed as
Where,
T = Temperature
R = Gas ideal constant
n = Number of moles in grams.
Our values are given as
The temperature is
Therefore the root mean square velocity would be
The fraction of velocity then can be calculated between the escape velocity and the root mean square velocity
Therefore the fraction of the scape velocity on the earth for molecula hydrogen is 0.1736
Answer:
If a runner exerts 350 J of work to generate 175 W of power, it took the runner 2 seconds to do the work.
Explanation:
Power is defined as the speed with which a job is done. In other words, power is a given amount of work done in a given unit of time. That is, it is the amount of work per unit of time that some object or system produces.
Its expression is:
where:
- P: Power developed by the force doing the work. Its unit of measure in the International System is the Watt (W)
- W: Work. Its unit of measure in the International System is the Joule (J)
- t: Time during which the work is carried out. Its unit of measurement in the International System is the second (s).
In this case:
Replacing:
and solving you get:
t= 2 s
