Answer:
the answer is points wand sun.
Explanation:
Answer:
110 g
Explanation:
q = mCΔT
where q is heat, m is mass, C is specific heat capacity, and ΔT is change in temperature.
Given q = 250 J, C = 0.228 J/g/°C, and ΔT = 10.0 °C:
250 J = m (0.228 J/g/°C) (10.0 °C)
m = 110 g
Answer:
The value of developed electric force is 
Solution:
As per the question:
Mass of the droplet = 1.8 mg = 
Charge on droplet, Q = 
Distance between the 2 droplets, D = 0.40 cm = 0.004 m
Now, the Electrostatic force given by Coulomb:
The magnitude of force is too low to be noticed.
Answer: B
To measure a lower-pitched sound wave, you would
measure fewer compressions per second. Pitch <span>relates to frequency by measuring how many times a second the
particles vibrate. Therefore, the lower-pitched sounds, the fewer compression waves or sound waves are produce because low-frequency
sounds have greater distance between each wave.</span>
Moreover,
the frequency of a wave is measured as the number of complete
back-and-forth vibrations of a particle of the medium per unit of time. <span>The universal unit for frequency used is
the Hertz (abbreviated Hz), where 1
Hertz = 1 vibration/second. </span>
Among the choices, the most appropriate unit for measuring volume is cubic centimeters. When measuring the volume of an object, 3 dimensions of an object is taken into consideration. By mathematical analysis, it is understandable that the unit would then be cubed since you would be multiplying 3 dimensions.
