Answer:
90 km/h
Explanation:
we just divide the distance by the time to get the speed.
Answer:
Fran's upstream time = 37.93 hrs
Fran's downstream time = 30.13 hrs
Explanation:
given data
speed in still water = 2.62 km/h
River flows = 0.3 km/h
Fran to swim upstream = 88 km
solution
we will apply here distance formula that is
distance = speed × time ...................1
put here value
so here
Fran's upstream speed = 2.62 km/h - 0.3 km/h = 2.32 km/h
Fran's downstream speed = 2.62 km/h + 0.3 km/h = 2.92 km/h
so
Fran's upstream time = = 37.93 hrs
Fran's downstream time = = 30.13 hrs
Answer:
latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion, and the heat of sublimation is the energy
Explanation:
<span>The transit or passage of a planet across the disk of the Sun may be thought of as a special kind of eclipse. As seen from Earth, only transits of the inner planets Mercury and Venus are possible. Planetary transits are far more rare than eclipses of the Sun by the Moon.</span>
