A weather balloon, rising vertically at 25.0 m/s, releases an instrument package when it is 100. meters above the ground. How ma

Illusion [34]

Answer:

7.74 seconds

Explanation:

u = 25 m/s

h = - 100 m

Let it takes time t to hit the ground.

Use second equation of motion

$h = ut-\frac{1}{2}gt^{2}$

$-100 = 25t-4.9t^{2}$

$4.9t^{2}-25t-100=0$

$t=\frac{25\pm \sqrt{625+4\times 4.9\times 100}}{2\times4.9}$

$t=\frac{25\pm 50.84}{9.8}$

Take positive sign as time can never be negative.

t = 7.74 s

Thus, the package takes 7.74 seconds to reach the ground.

Suppose you have a polarized light source in your lab that has an intensity of 1288 W/m2, where the electric field oscillates in

IRINA_888 [86]

Answer:

644 W/m²

0 W/m²

Explanation:

$I_0$ = Initial intensity of light = 1288 W/m²

$\theta$ = Angle of filter

Intensity of light is given by

$I=I_0cos^2\theta\\\Rightarrow I=1288\times cos^2(45)\\\Rightarrow I=644\ W/m^2$

The intensity of the transmitted light is 644 W/m²

$I=I_0cos^2\theta\\\Rightarrow I=1288\times cos^2(90)\\\Rightarrow I=0\ W/m^2$

The intensity of the transmitted light is 0 W/m²

A car is on a cruise control driving in a circle. Which are constant and which are changing? Speed, Velocity. Is the car acceler

grandymaker [24]

Answer:

Only the speed is constant.

The acceleration and velocity are changing.

Explanation:

The velocity of an object refers to its speed in a specific direction. Due to the fact that the car is driving in a circle, the direction of the car is changing. This makes the car not to have a constant velocity as this value changes each time the car makes a bend on the circular path. <em>(which is pretty much all the time).</em>

<em />

The acceleration is a direct derivative of the velocity of the car. As a result, if the velocity is changing, the acceleration is also changing.

<em />

Speed is a scalar quantity. This means it does not deal with the direction of the car. It only deals with how fast the car is moving. The car is on cruise control. this means that the speed of the car does not change.
