Answer:

Length of the Pendulum is 14.4 cm

Explanation:

Time period of simple pendulum is given by

T=2\pi \sqrt{\frac{L}{g} } \\

time taken for one oscillation is

T=\frac{time taken}{oscillations} \\T=\frac{8.75}{15} \\T=0.583 s

Pendulum length on the earth surface is

L=\frac{T^2g}{4\pi^2 }\\L=\frac{0.583\times 9.8}{4\pi^2 } \\L=0.144 m

Length of the Pendulum is 14.4 cm

Speedy, the super-swift squid, swims sideways at 5.3 m/s. If he suddenly uses his ink jet to accelerate at 15 m/s/s for 2.1 s, w
san4es73 [151]
Use v = vi + at
v = 5.3 m/s + (15 m/s^2)(2.1 s)
v = 5.3 m/s + 31.5 m/s
v = 36.8 m/s

An auto race takes place on a circular track. A car completes one lap in a time of 18.0 s, with an average tangential speed of 4
eduard

Answer:

(A) 0.3488 rad/sec

(B) 124.246 m                

Explanation:

We have given car completes one revolution in 18 sec'

So time period T= 18 sec

Tangential speed v = 43.4 m/sec

(A) Angular velocity is given by \omega =\frac{2\pi }{T}=\frac{2\times 3.14}{18}=0.3488rad/sec

(B) Tangential velocity is given v = 43.4 m /sec

We know that v=\omega r

r=\frac{v}{\omega }=\frac{43.4}{0.3488}=124.426m

When ionic bonds form compound structures in a solid state, they arrange in latticed, crystalline patterns.
Phantasy [73]

Answer:

Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound.

Part 2: Identify the independent, dependent, and constant variables
diamong [38]
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.
