Electrical energy is caused by moving particles that have a negative or positive charge. These charged particles are called electrons. The faster the electrons are moving, the more electrical energy they carry. Electrical energy commonly moves through a wire in an electrical circuit.

What is the wavelength of a 2500 kg truck traveling at a rate of 75km/h?
Pepsi [2]

m = mass of the truck traveling = 2500 kg

v = speed of the truck traveling = 75 km/h = 75 (km/h) (1000 m/ 1 km) (1 h /3600 sec) = 20.83 m/s

h = plank's constant = 6.63 x 10⁻³⁴

λ = wavelength of truck = ?

according to de broglie's principle, wavelength of truck is given as

λ = h/(mv)

inserting the values in the above equation

λ = (6.63 x 10⁻³⁴)/((2500) (20.83))

λ = 1.3 x 10⁻³⁸ m

the element copper cu has two naturally occurring isotopes. 69% of all coopers consist of atom with 34 neutrons, 31% of all samp
solniwko [45]
Answer : Average atomic weight of copper atoms will be 63.62 u. 

Explanation : For calculating average atomic weight for any given atom we use this formula,

m = Σm_{i} X % abundance

where, m - avg atomic mass of isotope.
and m_{i} - mass of isotope

on solving we get, 
m = [63 u X (69/100)] + [65 u X (31/100)] = 63.62 u.
