<h3>Question:</h3>

•What is the all time speed record for completing the iditarod?

Answer:

•In 2016, Dallas broke his own record, finishing in 8 days, 11 hours, 20 minutes and 16 seconds. In 2017, Mitch Seavey broke all previous records by finishing in 8 days, 3 hours, 40 minutes and 13 seconds, which currently stands as the fastest winning time for the Iditarod.

A mobile phone is 35% efficient. Over half an hour 11 kJ of energy is transferred to the phone.

kramer

Energy Transferre=11KJ
Efficiency=35%

<h3>☆Usefully transferred energy:-</h3>

$\\ \sf\longmapsto 35\%\:of 11$

$\\ \sf\longmapsto 35\%\times 11$

$\\ \sf\longmapsto \dfrac{35}{100}\times 11$

$\\ \sf\longmapsto \dfrac{385}{100}$

$\\ \sf\longmapsto 3.85KJ$

$\\ \sf\longmapsto 3850J$

How does the heat transfer (a change in temperature) that occurs through ocean currents affect the land?

vlabodo [156]

Answer:

Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth's land would be habitable.

A projectile is launched horizontally off a cliff. If the projectile is launched with more velocity, the time it spends in the a

Sedaia [141]

Answer:

If the projectile is launched horizontally the time it remains in the air will remain constant even if we increase the horizontal velocity.

Explanation:

The vertical displacement will be the same irrespective of the horizontal velocity assuming the projectile is launched from same height. The formula for vertical displacement is given by:

$y = v_{oy} - 1/2gt^{2}$

where, y = vertical displacement, t = time,

g = acceleration due to gravity,

$v_{oy}$ = Initial vertical velocity

Since, projectile is launched horizontally, therefore $v_{oy} = 0$

so the equation becomes

$y = - 1/2gt^{2}$

The above equation shows that time spend in air is not dependent on horizontal launched velocity as there is no horizontal velocity in the formula therefore the time in air will remain constant even if we increase the horizontal velocity.
