Answer:
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Explanation:
The pressure will 14. 0 g of co exert in a 3. 5 l container at 75°c is 4.1atm.
Therefore, option A is correct option.
Given,
Mass m = 14g
Volume= 3.5L
Temperature T= 75+273 = 348 K
Molar mass of CO = 28g/mol
Universal gas constant R= 0.082057L
Number of moles in 14 g of CO is
n= mass/ molar mass
= 14/28
= 0.5 mol
As we know that
PV= nRT
P × 3.5 = 0.5 × 0.082057 × 348
P × 3.5 = 14.277
P = 14.277/3.5
P = 4.0794 atm
P = 4.1 atm.
Thus we concluded that the pressure will 14. 0 g of co exert in a 3. 5 l container at 75°c is 4.1atm.

Answer:
<em>The input power is 200 W</em>
Explanation:
<u>Motor Efficiency</u>
The efficiency of a motor can be calculated as follows:
Where:
β = efficiency
Po = Output power
Pi = Input power
Solving for Pi:
The efficiency is β=0.75 and the output power is Po=150 W, thus the input power is:
The input power is 200 W
Answer: 55m
Explanation:
Given the following :
Driving speed = 90km/hr
Inattentive period (time) = 2.2s
Distance during inattentive period =
(driving speed * time)
Converting driving speed from km/hr to m/s
1000m = 1km
3600s = 1hour
Therefore,
90km/hr = (90 * 1000) / 3600
90km/hr = (90000)/ 3600 = 25m/s
Therefore ;
Distance during inattentive period =
(driving speed * time)
Distance during inattentive period = (25m/s × 2.2s) = 55m
Distance traveled during inattentive period is 55m
Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass (gasp, shudder, the horror!) then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.
