Mr. Hitch taught us about sedimentary, metamorphic, and igneous rocks. He described how they were formed, what they contain, and showed us samples of each. He is a good geologist.
The missing word and answer is: geologist.
Answer:
Capacitor
Explanation:
Capacitor ; A capacitor is a passive two-terminal electrical component that can store energy in an electric field electrostatically. It works as a small rechargeable battery that stores electricity. However, unlike a battery, it can charge and discharge in the split of a second. Capacitors are widely used to build different types of electronic circuits.
Answer:
Explanation:
M = 1.989 x 10^30 kg
R = 6.96 x 10^8 m
G = 6.67 x 10^-11 Nm²/kg²
Let the velocity is v.
v = 6.17 x 10^5 m/s
Answer:
= 8
Explanation:
noise from power mower = 106 dB
noise from rock concert = 115 dB
we would be applying the formula for the decibel level of sound to get the intensities.
(B) = 10 log \frac{I}{I₀}
I = intensity of sound
I₀= reference intensity = 10^{-12} W/m^{2}
- intensity of the power mower
106 = 10 log \frac{I}{10^{-12}}
10.6 = log \frac{I}{10^{-12}}
10^{10.6} = \frac{I}{10^{-12}}
I = 10^{10.6} x 10^{-12}
I of power mower = 0.0398 W/m^{2}
- intensity of the rock music
115 = 10 log \frac{I}{10^{-12}}
11.5 = log \frac{I}{10^{-12}}
10^{11.5} = \frac{I}{10^{-12}}
I = 10^{11.5} x 10^{-12}
I of rock music = 0.316 W/m^{2}
now the ratio of the intensity of the rock music to the power mower
= \frac{0.316}{0.0398}
= 8
False<span>, well designed weight training programs actually target most of the muscles in the body. A good weight training program includes many compound exercises to activate multiple muscle groups and promote muscle hypertrophy. Some isolation exercises may also be included to target a specific muscle and help it grow.</span>
