Why is honesty especially important in a scientist when the results of an experiment go against predictions❓❔
kramer
Because other scientists and science in general rely on their collegues' research which in turn allows development of our knowledge on the given subject. The more dont-to-earth reason may be safety. If someone performs an experiment without knowledge of its true results it might result in some danger to the safety of those perforning it without knowledge of all the risks.

You went 100 miles north and 14
skad [1K]

Answer:

82 degrees

Explanation:

consider your staying point to be the center of a circle. this center has the coordinates (0, 0).

the radius of the circle is the distance you walked East (14 miles).

I assume your teacher means as "angle of displacement" the angle between the East-West line going through your starting point and the direct line from your starting point to your current position.

then the 100 miles North is tan(displacement angle)×14.

as it is the same, if you first went North and then East, or the other way around. you end up at the same point, with the same coordinates.

so, again.

100 = 14×tan(angle)

tan(angle) = 100/14 = 50/7 = 7.142857...

the displacement angle is then 82 degrees.

What will be the change in momentum caused by a net force of 120N acting on an object for 2 seconds?
Vinvika [58]

The change in  momentum is 240 kgm/s

<u>Explanation:</u>

Given:

Force, F = 120N

Time, dt = 2 sec

Change in momentum, dP = ?

We know,

F = \frac{dP}{dt}

On substituting the value we get:

120 = \frac{dP}{2}\\ \\dP = 240 kgm/s

Therefore, change in  momentum is 240 kgm/s
