Pretty much any element(in your case sodium) contain these properties.
Atoms can be an ion, but not all ions are atoms. The difference between an atom and an ion has to do with net electrical charge. An ion is a particle or collection of particles with a net positive or negative charge. ... A stable atom contains the same number of electrons as protons and no net charge
Answer:
His average speed was 10.3199 m/s.
Explanation:
Answer:
The velocity of ball is 23.19 m/s
Explanation:
Given that,
Mass of football player = 80.0 kg
Mass of ball = 0.430 kg
Distance = 0.538
We need to calculate the time
Using equation of motion

We need to calculate the velocity
Using formula of velocity

We need to calculate the velocity of ball
Using conservation of momentum

Put the value into the formula

The velocity of ball is 23.19 m/s
Answer:
The correct answer should be high amplitude : )
Explanation:
A high energy wave is characterized by a high amplitude, a low energy wave is characterized by a low amplitud
Answer:
d = 2*0.87 = 1.75 cm
Explanation:
by using flow rate equation to determine the speed in larger pipe



= 591.10 cm/s
= 5.91 m/s
by Bernoulli's EQUATION


solving for v2
v2 = 10.53 m/s
diameter can be determine by using flow rate equation



r = 0.87 cm
d = 2*0.87 = 1.75 cm
