I believe it is C. because if driving through a flood it could wreck your car, and cause you to be injured in the flood. You should always find a higher ground because there is less of a chance for you to drown. If my answer is wrong in any way please let me know. Have a good day/night!
<span>C. Does eating less fat increase a mouse's lifespan?
(If a mouse eats less fat in its meals then will it live longer: compared to other mice lives.
</span>This is a testable question that can be answered by designing and conducting an experiment.
I think D could be correct as well.
My final answer is D.
Answer:
bust
Explanation:
At the same speed, kinetic energy is proportional to mass. The more massive object (the large bust) will have more kinetic energy.
Answer:
NO
Explanation:
The angular position of a diffraction null is given by
Asinθ=m λ=m c/f
Given that A is the slit width,
and m is an integer.
The wavelength of the second null satisfies
λ= A sinθ₁/2
of which if there were distinct third null it will satisfy
sinθ₂=3λ/A= 3* sin 45/2
λ=(3*0.7071)/2
λ=2.121/2
λ=1.060
Of which 1.060 is greater than 1
Answer:
a) 4.8×10^-5T
b) 7.38×10^-7seconds
Explanation:
The centripetal force in a magnetic field is given by:
qvB= mv2/r
Where q= charge of the ion
m= mass of the ion
r= radius of the circular path
B= magnetic field
V= velocity
Rearranging to make B subject of formular gives:
B=mv/r
B= [(9.11×10^-31)×(5.87×10^5)]/ [(1.6×10^-19)×(6.81×10^-2)]
B = (5 34×10^-25)/(1.099×10^-20)
B= 4.86×10^-5T
b) T =( 2 pi × r)/v
T = 2 × 3.142 x (6.81×10^-2) / (5.87×10^5
T = 0.428/ (5.87×10^5)
T = 7.38 × 10^-7seconds
