6859.079 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²
Magnitude of the force of the track on the car when the car is at the top of the loop is 6859.079 N
Answer: B. Increases
Explanation:
An electron is a negatively charged particle, while a proton is positively charged.
Opposites attract so as it approaches the proton the force of attraction will increase.
Answer:
electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
Explanation:
Since there are 3 links in the spring, the angel θ for
equilibrium of the spring is the angle where there are no nte motion of the
spring. It can be easily be solve by jus diving 360 by the number of links.
360/3 = 120 degree is the angle of equilibrium
