Answer:
The ion has more protons than electrons.
Explanation:
Answer:
Explanation:
height lost h = 300 sin60
= 259.8 m .
gravitational potential energy = mgh
= 5000 x 9.8 x 259.8
= 1273 x 10⁴ J
Kinetic energy
= 1/2 mv²
= .5 x 5000 x 60²
= 900 x 10⁴ J
there is loss of kinetic energy = 373 x 10⁴ J.
This loss in energy is due to kinetic friction that came into action when the sled slipped downwards.
The lost energy is converted into heat energy or thermal energy.
Answer:
utilization / effects
Explanation:
Utilization equipment are those equipment that makes use of electric energy for the purpose of chemical, electronic, lighting, heating, electro-mechanical or other alike purposes. Hence utilization best suits the first question mark in the question. Secondly, there are associated effects when current flows through a conductor, not responses.
1. Jumping off a building
2. Hitting a tennis ball
3. Swinging a bucket of water in a circle
Answer:
7.8 mm
Explanation:
Wavelength = λ = 710 nm = 710×10⁻⁹ m
Distance between light sources = L = 9 m
Diameter of pinhole = d = 1 mm = 1×10⁻³ m
Rayleigh Criterion
Distance between difraction pattern is 7.8 mm.
