The skier's speed at time <em>t</em> is

<em>v</em> = (23 m/s²) <em>t</em>

To reach a speed of 9.3 m/s, the skier would need

9.3 m/s = (23 m/s²) <em>t</em>

<em>t</em> = (9.3 m/s) / (23 m/s²)

<em>t</em> ≈ 0.404 s

This problem has been solved!

RideAnS [48]

Answer:

Option (a)

Explanation:

We will discard options that don't fit the situation:

Option b: <em>Incorrect </em>since if the driver "hits the gas" then velocity is augmenting and it's not constant.

Option c and d: <em>Incorrect </em>since the situation doesn't give us any information that could be related directly to the terrain or movement direction.

Option a: Correct. At <em>stage 1</em> we can assume the driver was going at constant speed which means acceleration is constantly zero. At <em>stage 2 </em>we can assume the driver augmented speed linearly, this is, with constant positive acceleration. At <em>stage 3 </em>we can assume the driver slowed the speed linearly, with constant negative acceleration.

Two positive charges of magnitude 20 micro C and 100 micro C are placed at a distance of 150cm. Calculate the force of repulsion

Luba_88 [7]

$first \: positive \: charge = q1 = 20$

$1micro \: = {1}^{ - 6}$

$1q = 20 \times 10 {}^{ - 6}$

$second \: charge = q2 = 100 \times 10 {}^{ - 6}$

$formula = f = \frac{k \times q1 × q2}{d {}^{2} }$

remember

$k = 9 \times {10}^{9}$

change distance 150cm to 1.5m

putting values

f = $\frac{9 \times 10 {}^{9} \times 20 \times 10 {}^{ - 6} \times 100 \times {10}^{ - 6} }{1.5 {}^{2} }$

A quantity that does not have direction is referred to as a

Hatshy [7]

B

A quantity which does not depend on direction is called a scalar quantity. Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude. ... The resulting motion of the aircraft in terms of displacement, velocity, and acceleration are also vector quantities.
