This is defiantly not from Elementary School.
The answer is: C - both answers above are correct.
Explanation:
The SI base units for newtons is: kg x m/s ².
When separated it is basically: the amount of force that one kilogram multiplied by one meter per second squared (this is the acceleration)
Answer:
98.12 m
Explanation:
Initial speed(v) = 25.0 m/s
Coefficient of static friction (u) = 0.650
The minimum value of the coefficient of kinetic friction should be the coefficient of static friction.
Kinetic friction is given as
umg = ma (a is the required acceleration)
We then have
a = -ug
= -(0.65*9.8)
= -6.37 m/s^2
The shortest distance d is obtained by
d = (V^2 - v^2)/ 2a
V = 0 m/s (final velocity)
d = (0 - 25^2) / 2(-6.37)
d = -625/-6.37
d = 98.12 m
Answer:
Use the formula ∆H = m x s x ∆T to solve.
Explanation:
Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve.
<em><u>Answer:</u></em>
You can only hear it at night. The reason for this upward diversion of sound in the daytime versus the downward diversion at night is the strong dependency of the speed of sound in the atmosphere on temperature. The atmosphere acts like a lens that focuses sound energy upwards during the day, but keeps it at ground level during the night.
<em><u>Or</u></em>
<em><u>During the day, the sound bends away from the ground; during the night, it bends towards the ground. Hence at night you have additional "sound" reaching you, making it louder.</u></em><em><u> </u></em>
This is the Answer for your question :3
I hope you are having a great day ❤️❤️❤️❤️❤️
