In neutral state the atom got an equal number of protons (+) and electrons (-). If you lose and electron then you will have 1 more proton than electron, so you have a +, but if you gained an electron, then you'd have one more electron than protons, so you'd get a -.
<span>Fx: carbon has 6 protons and 6 electrons. If carbon loses an electron, then the carbon atom would have 6 protons and only 5 electrons, then you'd have 6+ and 5-, which is 1 more plus and minuses, so you have C+. </span>
<span>If Carbon gained an electron, then you'd have 6+ and 7-, which is 1 more minus than pluses, so you'd have C-. </span>
<span>Last example, if you gained 2 electrons, then you'd have 6+ and 8-, which is 2 more minuses than pluses, which would give you an C-- (Also known as: C2-)</span>
For example, a bonfire/campfire and a burning candle
Answer:
1. Speed and velocity both involve a numeric rate describing the distance traveled by a body in a unit of time. However, speed describes the rate of a body traveling in any direction in a unit of time, while velocity describes the rate of a body traveling in a particular direction in a unit of time.
2. Answers may vary, but should resemble the following:
Average velocity explains the velocity the body traveled overall, not taking into consideration each spot in the trip. If a car moves at 65 km/h on average, it may have slowed down for some parts and sped up for others. Overall though, it would have made a certain distance of travel within a specified unit of time that totals the average velocity of 65 km/h.
Instantaneous velocity explains the velocity of a body at a particular instant of the trip. The instantaneous velocity of a car stopped at a stop sign would be 0 m/s even if it was moving before and will continue to move after this stop. The velocity at that particular instant is the instantaneous velocity.
Uniform velocity is when the distance being covered is changing uniformly with time. For example, if a car moves 20 km every 30 minutes and continues to do so in the same direction, it's traveling with a uniform velocity.
3. a=v2−v1t
a=20 m/s−60 m/s6 s
a=−406
a = –6.7 m/s2
4. v2 = v1 + at
v2 = 14 m/s + (3 m/s2 × 6 s)
v2 = 14 + 18
v2 = 32 m/s
5. v=st
v=375 km5 h
v = 75 km/h
6. First, convert the minutes to seconds. Since there are 60 seconds in one minute, multiply:
60 × 15 (minutes) = 900 seconds
s = v × t
s = 6 m/s × 900 s
s = 5,400 m
7. t=sv
t=80 km35 km/hr
t = 2.29 hr
8. a=v2−v1t
a=50 m/s−15 m/s4 s
a=35 m/s4 s
a = 8.75 m/s2
9. vav=v1+v22
vav=15 m/s+50 m/s2
vav=65 m/s2
vav = 32.5 m/s
10. a=v2−v1t
a=0 m/s−11.5 m/s3.5 s
a = –3.29 m/s2
Explanation:
Newton also understood that white light can be separated into its components because each ray of color is deviated by the glass of the prism by a different amount. He realized, for example, that red light is consistently less deviated than violet light.
Answer: It is B 38% have a good day :DDD
