Part 2: Identify the independent, dependent, and constant variables

Physics
1 answer:
diamong [38]2 years ago
4 0
ANSWER:

IV, Type of dish detergent. DV, height of foam. CV, type of container, amount of water in container, temperature of water, time the container is agitated.

Explanation:

Independent variable(IV)- what you change during the experiment.
dependent variable(DV)- what you're measuring during an experiment. The dependent variable is DEPENDENT because it's results DEPEND on the independent variable at play.
Constant variables(CV)- things that do not change in order to isolate the tested variables as much as possible.

kompoz [17]

Answer:

103063860 Pa

Explanation:

\rho = Density of seawater = 1030 kg/m³

g = Acceleration due to gravity = 9.81 m/s²

h = Depth at which pressure is being measured = 10.2 km

The gauge pressure is given by

p=\rho gh\\\Rightarrow p=1030\times 9.81\times 10.2\times 10^3\\\Rightarrow p=103063860\ Pa

Therefore, the gauge pressure at a depth of 10.2 km is 103063860 Pa

Suppose a 2.0×10−62.0×10−6-kgkg dust particle with charge −1.0×10−9C−1.0×10−9C is moving vertically up a chimney at speed 6.0 m/
ipn [44]

Answer:

Explanation:

mass of particle m = 2 x 10⁻⁶ kg

charge q = 1 x 10⁻⁹ C

electric field E = 2000 N/C

force on charge = E q

= 2000 x  1 x 10⁻⁹

acceleration = force / mass

= 2000x10⁻⁹ / 2 x 10⁻⁶

= 1 m /s²

initil velocity u = 6 m /s

distance s = 4 x 10⁻²

time = t

s = ut + .5  t²

4 x 10⁻² = 6t + .5 x 1 x t²

t² + 12t - .08 = 0

= .0067 s .

= 6.7 ms .

The highest barrier that a projectile can clear is 12.2 m, when the projectile is launched at an angle of 13.0 ° above the horiz
Orlov [11]

consider the motion in vertical direction

v = initial velocity in the vertical direction = ?

v' = final velocity in the vertical direction at the highest point = 0 m/s

a = acceleration due to gravity = - 9.8 m/s²

h = maximum height = 12.2 m

Using the kinematics equation

v'² = v² + 2 a h

0² = v² + 2 (- 9.8) (12.2)

v = 15.5 m/s

let assume that velocity of launch be v₀

θ = angle of launch = 13

vertical component of the velocity of launch is given as

v = v₀ Sinθ

15.5 = v₀ Sin13

v₀ = 69 m/s

When an object is fully magnetized, all of its magnetic domains will be ?
Lemur [1.5K]

Answer:

When all of the domains are aligned, the material is said to be magnetically saturated. When a material is magnetically saturated, no additional amount of external magnetization force will cause an increase in its internal level of magnetization.
