What must be the initial velocity of a rocket that accelerates for 10.2 seconds at 5.31 m/s2 and covers 3912 m?
A. 276 m
B. 356 m/s
C. 107 m/s
D. 384 m/s
Answer: B
Explanation: 3912=10.2v +1/2(5.31)(10.2)^2 -> v≈ 356.45 (B)

what is the frequency of a ocean wave that is traveling at a speed of 45 m/s if it has a wavelength of 3 meters? please show work
Answer:
15 miles per hour
Explanation:
45/3=15
Answer:
15 Hz or Hertz
Explanation:
To find the frequency of a wave, divide the velocity by the wavelength.
f=velocity/wavelength
We know the ocean wave is traveling at 45 meters per second, and it has a wavelength of 3 meters. Therefore, the velocity is 45 m/s and the wavelength is 3 m.
velocity=45
wavelength=3
Substitute these values into the formula.
f=45/3
Divide 45 by 3
f=15
Add appropriate units. Frequency uses Hertz or Hz.
f=15 Hertz
The frequency of the ocean wave is 15 Hertz.
What two charges could increase electrical force between objects
Answer:
From Coulomb’s Law of electrostatics the force of attraction or repulsion between two charged bodies is inversely proportional to the square of the distance between their two centers.
If the distance between them is doubled then the force is one-fourth of the original force.
If the distance between them is halved then the force is four times than the original force.

Answer: A
Biology
Explanation:
Psychological researchers study genetics in order to better understand the biological factors that contribute to certain human behaviour.
Because bodies with a particular genetic code are related in some certain behavioral forms and actions such as thought, feelings, attitude e.t.c
