Answer:
270 m
Explanation:
We can find the distance travelled by the car by using the following suvat equation:
where
s is the distance travelled
u is the initial velocity
v is the final velocity
t is the time
For the car in this problem,
u = 0
v = 45 m/s
t = 12 s
Substituting into the equation, we find:
Answer:
Explanation:
Given
Temperature of Hot reservoir 
Temperature of Cold reservoir 
Heat reservoir 
Work done 
heat Exhaust 
L.H.S=R.H.S
thus it follows first law
Cycle Efficiency
Carnot efficiency is less than cycle thus it violates second law
Answer:
0.5 V
Explanation:
The electric potential distance between different locations in an electric field area is unaffected by the charge that is transferred between them. It is solely dependent on the distance. Thus, for two electrons pushed together at the same distance into the same field, the electric potential will remain at 1 V. However, the electric potential of one of the two electrons will be half the value of the electric potential for the two electrons.
Answer;
light fixtures
Explanation;
Radioactive isotopes have a variety of applications. They are useful because either we can detect their radioactivity or we can use the energy they release.
These uses includes;
- Radioactive Dating; Radioactive isotopes are useful for establishing the ages of various objects.
- Medical Applications; Radioactive isotopes have numerous medical applications; sterilization of equipment, diagnosing and treating illness and diseases.
- Detection of leaks in building structures
- Irradiation of Food; the radiation emitted by some radioactive substances can be used to kill microorganisms on a variety of foodstuffs, extending the shelf life of these products. etc.
