Answer:
Because of height and lower atmospheric pressure.
Explanation:
Atmospheric pressure affects aerodynamic drag, lower pressure means less drag. At the altitude of Denver the air has lower pressure, this allows baseball players to hit balls further away.
Another aerodynamic effect is the Magnus effect. This effect causes spinning objects to curve their flightpath, which is what curveball pitchers do. A lower atmospheric pressure decreases the curving of the ball's trajectory.
Answer:
Positive velocity and negative acceleration
Explanation:
An object moving in the positive direction has a positive velocity.
An object that's slowing down while moving in the positive direction has a negative acceleration.
Answer: Well there is a simple solution which is death..
Answer:
C : 1.4*10^(-11) N.
Explanation:
q_1 = q_2 = 1.6 * 10^(-19)
R^2 = (1)^2 + (4)^2 = 1.7 * 10^(-17) m^2
The coulomb's law is as follows:
F_e = k*q_1*q_2 / R^2
F_e = k*q^2 / R^2
F_e = (9.0*10^9) * (1.6 * 10^(-19))^2 / 1.7 * 10^(-17)
F_e = 1.35 * 10^(-11) N
Hence, answer closes to obtained is option C : 1.4*10^(-11) N.
