If there was no friction the car will continue to move at a constant speed in a straight line.
Answer:
I = 11.26 mA
Explanation:
given,
V = 0.7 V length = 80 m
diameter = 0.2 mm = 0.02 cm
radius = 0.01 × 10⁻² m
ρ for gold wire = 2.44 × 10⁻⁸ ohm-m at 20 °C
A = cross sectional area = π r² = π (0.01 × 10⁻² )²
= 31.4× 10⁻⁹ m²
R = 62.165 Ω
I = 11.26 mA
Answer:
all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
Explanation:
Electrostatic interactions, have many rare manifestations in nature, which causes many reasons to study them.
- Lightning is a very striking form of electricity
- The biological processes are governed by currents of inanes and potential differences
- The transfer of nutrients and fertilizers to plants is with ion exchange, electrostatic forces
- all modern electronics is based on electricity
- the electric charge in very dry places, creates high currents that can create fires or kill people
In summary all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
The physics is involved in many daily activities,
Forrxample,
1. At the time of wake up when the alarm clock rings, the sound from the alarm clock is studied by using physics, the angular motion of the pins on the clock.
2. The oscillation and time period of the minute, second and hour hand.
3. The tranformation of our energy from food to the energy for motion of our body.
4. The balance of our house equipments on the tab
Answer:
clouds can consist of dry air mixed with liquid water drops, ice particles, or both. low, shallow clouds are mostly made of water droplets of various sizes. thin, upper level cloud are made of tiny ice particles.
