In order to increase the amount of work completed, it is necessary to decrease the force applied to an object. decrease the time
wlad13 [49]
<span> <span> The answer to your question is: increase the force applied to the object.

Two items are provided as a basis for that conclusion:
1. According to Newton's Second Law of Motion, the formula for finding force is: F = ma
where F is the force,
m is the mass of an object,
and a is the acceleration of the object.

And 2: work = force x distance or W = F x d.</span></span>

RideAnS [48]
Reflection occurs in many scenarios in our everyday life. Reflection occurs
when light travels in one medium and comes into contact with another.
However, what if a light wave is moving from one location to another but
the mediums stay the same, what happens to that light wave?*

it will reflect with the same amount of intensity

A jet airliner moving initially at 612 mph (with respect to the ground) to the east moves into a region where the wind is blowin
Ganezh [65]

Answer:

966.22 mph

Explanation:

Velocity of plane with respect to wind (Vp,w)= 612 mph east

velocity of wind with respect to ground, (Vw,g) = 362 mph at 15° North of

east

Write the velocities in vector form

V_{p,w}=612\widehat{i}

V_{w,g}=362\left ( Cos15\widehat{i}+Sin15\widehat{j} \right )= 349.67\widehat{i}+93.69\widehat{j}

Use the formula for the relative velocity

V_{p,w}=V_{p,g}-V_{w,g}

Where, V(p,w) is the velocity of plane with respect to wind

V(p,g) is the velocity of plane with respect to ground

V(w,g) is the velocity of wind with respect to ground

So, V_{p,g}=V_{p,w}+V_{w,g}

V_{p,g}=\left ( 612+349.67 \right )\widehat{i}+93.69\widehat{j}

V_{p,g}=961.67\widehat{i}+93.69\widehat{j}

Magnitude of velocity of lane with respect to ground

V_{p,g} = \sqrt{961.67^{2}+93.69^{2}}

V(p,g) = 966.22 mph
