By definition we have the momentum is:
P = m * v
Where,
m = mass
v = speed
Before the impact:
P1 = (0.048) * (26) = 1.248 kg * m / s
After the impact:
P2 = (0.048) * (- 17) = -0.816 Kg * m / s.
Then we have that deltaP is:
deltaP = P2-P1
deltaP = (- 0.816) - (1,248)
deltaP = -2,064 kg * m / s.
Then, by definition:
deltaP = F * delta t
Clearing F:
F = (deltaP) / (delta t)
Substituting the values
F = (- 2.064) / (1/800) = - 1651.2N
answer:
the magnitude of the average force exerted on the superball by the sidewalk is 1651.2N
As the particles in a soup reach the boiling point, the kinetic energy of the molecules will start increasing and ultimately bubbles will be created in the soup and it will slowly start to vaporize. Boiling point of a liquid is the temperature at which the vapor pressure of the liquid will become equal to the atmospheric pressure.<span> </span>
We have that for the Question,it can be said that the field has a <u>value </u>of
From the question we are told
a small object with a charge of magnitude q creates an electric field. at a point 1.0 m to the north of the charge the field has a value of 2.0 n/c directed south. at a <em>point </em>0.5 m to the west of the <em>charge </em>the field has a value of
<h3> Electric
field </h3>
Generally the equation for the <em>electric</em> field is mathematically given as

The displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.
A longitudinal wave is a wave that vibrates the medium in the same direction in which the wave energy travels.
The answer would be C.
