Answer:
The function has a maximum in 
The maximum is:
Explanation:
Find the first derivative of the function for the inflection point, then equal to zero and solve for x
Now find the second derivative of the function and evaluate at x = 3.
If 
the function has a maximum
If 
the function has a minimum
Note that:
the function has a maximum in
The maximum is:
Answer:
m1v1=m2v2, v2=4.3m/s KE=(0.5)(2.94)(4.3)=6.2J
Do you mean ‘Does a larger object have less attraction than a smaller object?’ If so, then the answer is objects with a larger mass exert more attraction while objects with a smaller mass have less attraction.
Explanation:
Diffraction is a characteristic phenomenon for waves, and is based on their variance to find an obstacle or a crack. The diffraction and interference are inseparable phenomena, which are so harder to identify. Since diffraction is a specific type of interference.
if the point are in the order 2, and
the equation is d×senx=mL y at m=2
Answer: E. None of the above
Explanation: The energy of a photon is given by the formula below.
E=hf or E = hc/λ
E = energy, h = planck constant, c= speed of light and
λ= wavelength.
From E=hf we can see that energy is directly proportional to frequency since h is a constant, this implies that as we move up the visible light spectrum, red light has the least frequency this accounting for the lowest energy while violet has the largest energy accounting for a very high energy.
Blue light is higher in the spectrum than red light.
This implies that blue light has more energy than red.
Visible light is part of the electromagnetic spectrum which implies that they all travel with the same speed of a constant value ( speed of light = 3* 10^8 m/s).
Thus in conclusion, blue light has more energy that red light but they both travel with the same speed.
This point nullifies the options thus making none of it correct.
