The Action Force of this scenario is the pushing force of the Diver. The Reaction Force is the raft pushing back on the diver. 

The Third Law of Motion states that "For every action, there is an equal and opposite reaction." Now when the diver dives off the raft, the raft is also pushing the same amount of force as the diver did as he dives off. The diver will then move forward and the raft on the other hand will move backwards.

The movement of the raft shows the opposite force. It will move backwards depending on how strong the diver will push off on the raft. And the amount of force he pushes on it, the raft will exert the same force so the stronger the force of the diver, the farther he will go because the raft will push him in that same direction as it goes backwards.

The frequency of a microwave signal is 9.76 ghz. what is its wavelength? (c = 3.00 × 108 m/s)
dolphi86 [110]
The basic relationship between frequency of an electromagnetic wave and wavelength of the wave is
c = \lambda f
where c=3 \cdot 10^8 m/s is the speed of light.

Manipulating the equation, we can rewrite it as
\lambda =  \frac{c}{f}

The frequency of the wave in our problem is
9.76 GHz = 9.76 \cdot 10^9 Hz
so if we use the previous formula, we find the correspondant wavelength:
\lambda =  \frac{3 \cdot 10^8 m/s}{9.76 \cdot 10^9 Hz} =0.031 m

What is the magnitude of the electric field in a region where the potential is given by the expression V = ax2 + b where a = −50
sweet [91]

Answer:

E = 1000 x

Explanation:

The electric potential and the electric field are related by the formula

        dV = - E . dx

Bold represents vectors.

The point represents the scalar product, in this case we calculate the electric field in the x-axis and the potential is also in this axis so the scalar product is reduced to the algebraic product

        E = dV /dx

Let's make the derivative

        E = - 2ax

Let's replace the values

        E = -2 (-500) x

        E = 1000 x

Consider the three dip1acement vectors A = (3i - 3j) m, B = (i-4j) m, and C = (-2i + 5j) m. Use the component method to determin
tia_tia [17]

Answer with Explanation:

We are given that

A=3i-3j m

B=i-4 j m

C=-2i+5j m

a.D=A+B+C

D=3i-3j+i-4j-2i+5j

D=2i-2j

Compare with the vector r=xi+yj

We get x=2 and y=-2

Magnitude=\mid D\mid=\sqrt{x^2+y^2}=\sqrt{(2)^2+(-2)^2}=2\sqrt 2 units

By using the formula \mid r\mid=\sqrt{x^2+y^2}

Direction:\theta=tan^{-1}\frac{y}{x}

By using the formula

Direction of D:\theta=tan^{-1}(\frac{-2}{2})=tan^{-1}(-1)=tan^{-1}(-tan45^{\circ})=-45^{\circ}

b.E=-A-B+C

E=-3i+3j-i+4j-2i+5j

E=-6i+12j

\mid E\mid=\sqrt{(-6)^2+(12)^2}=13.4units

Direction of E=\theta=tan^{-1}(\frac{12}{-6}=tan^{-1}(-2)=-63.4^{\circ}

Car a is heading north with a velocity of 14 m/s. car b is traveling north also, with a velocity of 19 m/s. what is the relative
kicyunya [14]
a.)  Relative velocity = velocity of car B - velocity of car A
                             = 19 - 14
                             = 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)
