Answer:
7.468 kN
Explanation:
Here the force of 7468 Newton is given.
Some of the prefixes of the SI units are
kilo = 10³
Mega = 10⁶
Giga = 10⁹
The number is 7468.0
Here, the only solution where the number of significant figures is kilo
1 kilonewton = 1000 Newton


So 7468 N = 7.468 kN
According to the information given, the Heisenberg uncertainty principle would be given by the relationship

Here,
h = Planck's constant
= Uncertainty in velocity of object
= Uncertainty in position of object
m = Mass of object
Rearranging to find the position

Replacing with our values we have,


Therefore the uncertainty in position of electron is 
Each of those choices has some truth to it, but three of the five choices also include some nonsense.
A. The voltage <em>divides proportionally</em> among all resistors in the circuit.
<em>B. </em> As more resistors are added, the current will decrease. <em>True,</em> because the total resistance will increase.
C. The <em>sum </em>of the voltage drops will be the total voltage in the circuit.
D. The current is the same <em>through</em> all resistors in the circuit.
<em>E.
</em> The equivalent resistance will be greater than the individual resistors. <em>True,</em> because the equivalent resistance is the sum of the individual resistors.
Answer:
Converted to heat energy
Explanation:
Some of the elastic potential energy is transformed into heat energy. When we stretch a rubber band, it is often observed that the rubber becomes warmer after the stretch and even during the stretch.
Some energy in the band initially at rest will be converted into elastic potential energy and heat energy as it is stretched .
- The heat energy is not usually accounted for since the major concern most times is the elastic energy.
- In this process, heat energy becomes a waste energy.
- By deducing the efficiency, we would find that this transformation is not efficient as predicted by one of the laws of thermodynamics.
Answer:
a) 0.05719 km/s^2
b) 0.00921 km/s^2
Explanation:
average acceleration can be calcuated as follows
a)
- In the initial time (
), just before of race start the rocket is at rest. So
.
- After 3.22 s the rocket reach 663 km/h, So
and the
. We convert units from km/h to km/s to have the same time units (seconds) the velocity would be:

(take into accoun that 1 h=3600 s)
and acceleration is:

b)
acceleration while stopping is calculate with the same formula but now
-we define the initial time (
) the instant just before begining the stopping. At this instant the velocity is 663 km/h which is the same as 0.18467 km/s.
-After 20 seconds the rocket stops. So tex]t_f=20 s[/tex] and 
So, acceleration is:
