Answer:
c- heat for electricity generation process comes from nuclear fission
Explanation:
nuclear fission is splitting of atoms to release energy held at nucleus of atoms
Answer:
1: is A
2: is C
Explanation:
1: because all other option would imply that the truck was not moved from from its previous position due to the lack of work / force exerted by the car
2: this is because the less dense ball will have less opposing force action on it causing it to move / accelerate / go at a faster speed
Heya!!
For calculate aceleration, lets applicate second law of Newton:

<u>Δ Being Δ</u>
F = Force = 183 N
m = Mass = 367 kg
a = Aceleration = ?
⇒ Let's replace according the formula and clear "a":

⇒ Resolving

Result:
The aceleration is <u>0,49 meters per second squared (m/s²)</u>
Good Luck!!
Answer:
Tech A is right.
Explanation:
Its the ability of quartz crystal that if we apply a mechanical stress on them by an applied force then they can produce the electricity or voltage. This phenomenon of producing electricity by squeezing a crystal is termed as piezoelectricity or a piezoelectric effect.
The distance travelled during the given time can be found out by using the equations of motion.
The distance traveled during the time interval is "13810.8 m".
First, we will find the deceleration of the motorcycle by using the first <em>equation of motion</em>:

where,
vi = initial velocity = (518 km/h)
= 143.89 m/s
vf = final veocity = 60 % of 143.89 m/s = (0.6)(143.89 m/s) = 86.33 m/s
a = deceleration = ?
t =time interval = 2 min = 120 s
Therefore,

a = -0.48 m/s²
Now, we will use the second <em>equation of motion </em>to find out the distance traveled (s):

<u>s = 13810.8 m = 13.81 km</u>
