Answer:

D. Select fresh, small flowers that will match the décor

Explanation:

This question would probably fall under Floral Design instead of Physics, but selecting these small flowers can help create a better visual look and floral design overall.

A Chinook salmon can jump out of water with a speed of 6.70 m/s6.70 m/s . How far horizontally dd can a Chinook salmon travel th

aksik [14]

Answer:

R = 3.88 m

Explanation:

As the Chinook salmon leaves the water till it gets back into the water it is performing a projectile motion with the following parameters:

V₀ = Launch Speed = 6.7 m/s

θ = Launch Angle = 29°

R= Range of Projectile= Horizontal Distance Covered by Chinook salmon= ?

The value of the range of a projectile is given by the following formula:

R = (V₀² Sin 2θ)/g

R = [(6.7 m/s)² Sin {(2)(29°)}/(9.8 m/s²)]

R = [(6.7 m/s)² Sin (58°)/(9.8 m/s²)]

<u>R = 3.88 m</u>

Ask Your Teacher The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 2.0 rev/s

adell [148]

Answer:

$\theta = 20\ rev$

Explanation:

Case 1

Given,

initial angular speed = 0 rev/s

final angular speed = 2 rev/s

time, t = 7 s

angular acceleration of the washer

$\alpha = \dfrac{\omega_f-\omega_i}{t}$

$\alpha = \dfrac{2-0}{7}$

$\alpha = 0.286\ rev/s^2$

using equation of rotational motion

$\omega_f^2 = \omega_i^2 + 2 \alpha \theta_1$

$2^2 = 0^2 + 2\times 0.286 \times \theta_1$

$\theta_1 = 7 rev$

Case 2

Given,

initial angular speed = 2 rev/s

final angular speed = 0 rev/s

time, t = 12 s

angular acceleration of the washer

$\alpha = \dfrac{\omega_f-\omega_i}{t}$

$\alpha = \dfrac{0-2}{13}$

$\alpha = -0.154\ rev/s^2$

using equation of rotational motion

$\omega_f^2 = \omega_i^2 + 2 \alpha \theta_2$

$0^2 = 2^2 + 2\times (-0.154) \times \theta_2$

$\theta_2 = 13 rev$

total revolution in this case

$\theta = \theta_1 + \theta_2$

$\theta =7 +13$

$\theta = 20\ rev$

total revolution of the washer is equal to 20 rev.

4. An object is thrown vertically upward with a speed of 25 m/s. How much time passes before it

vlada-n [284]

Answer:

<em>Option b is correct: 4.1 s</em>

Explanation:

<u>Vertical Launch</u>

An object launched thrown vertically upward where air resistance is negligible, reaches its maximum height in a time t, given by the equation:

$\displaystyle t=\frac{v_o}{g}\qquad\qquad[1]$

Where vo is the initial speed and g is the acceleration of gravity g=9.8 $m/s^2$ .

Once the object reaches that point, it starts a free-fall motion, whose speed is (downward) given by:

$v_f=g.t\qquad\qquad[2]$

The object considered in the question is thrown with vo=25 m/s. The time taken to reach the maximum height is given by [1]:

$\displaystyle t=\frac{25}{9.8}=2.551\ sec$

The object starts its falling motion and at some time, it has a speed of vf=15 m/s. Let's find the time by solving [2] for t:

$\displaystyle t=\frac{15}{9.8}=1.531\ sec$

The total time taken by the object to go up and down is

$t_t=2.551\ s+1.531\ s=4.081\ s$

a. This option is incorrect because it's far away from the answer.

d. This option is incorrect because it's far away from the answer.

b. This option is correct because it's a good approximation to the calculated answer.

e. This option is incorrect because it's far away from the answer.

c. This option is incorrect because it's far away from the answer.
