In #8, the distance and the (magnitude of displacement) are equal, because he crawled in a straight line.
Displacement = (straight-line distance from start-point to end-point) in the direction from start to end, regardless of what route was actually followed.
Displacement = 5m, in the negative direction.
In #9 . . . distance will be the same. Displacement is going to be the same magnitude, but in the positive direction.
This is so simple that it's hard to talk about.
In #8, "What was the bug's distance ?". "Distance was 5 meters.". "What was the bug's displacement ?", "Displacement was 5 meters backwards."
In #9, What was the bug's distance ?". "Distance was 5 meters.". "What was the bug's displacement ?", "Displacement was 5 meters forward."
Answer:
Negative electric charges
Answer:
The amount that is "vented" out by "the fans" is <u>$0.50</u> for 10 hours.
Option: a
<u>Explanation</u>:
"Energy discharged by air in every hour" can be determined by,
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat (units J/kg∙K)
∆T = 10 hours
Q = 576 × 1.00 × 10
Q = 5760 kJ/hours
W = 1.6 kwh
We know that, “Coefficient of performance” (COP)
Given that, COP = 3.2
W = 0.5 kwh
The unit cost of electricity is $0.10/kWh
The unit cost of electricity is $0.10/kWh
Unit electricity cost for 10 hours = 0.5 × 10 × 0.1$
Unit electricity cost for 10 hours = $0.5
The amount that is "vented out" by "the fans" is $0.50 for 10 hours.
Answer:
The correct answer is B. 0.64 m/s²
Explanation:
According to the Newton's Second law of motion acceleration of an object by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.
Mathematically,
F ∝ a
F = ma
Given data:
Force = F = 35 N
Mass = m = 55 kg
acceleration = a = ?
F = ma
a = F/m
a = 35/55
a = 0.64 m/s²
Explanation:
A small piece of energy is called as Electron. It cannot be broken down further into smaller pieces. Photon is a basic unit of light. Photons always travel. They are in a continuous motion. So when electron needs energy, They absorb light. The light is absorbed or emitted in the form of photons. Each photon contains energy which is absorbed by the electron to gain its energy. After absorbing the photon, electron moves towards a higher energy level. So when an electron absorbs a photon, energy is gained by the electron.
