Assume orange is going from left to right and apple is going from right to left 
If mv is the momentum of apple at angle θ to the x axis, 
In the x direction 
0.130*v cos θ = (0.170*1.23) -(0.130*1.08) 
0.130*v cos θ = 0.0687-------------------------2 

In the y direction 
0.130*v sin θ = (0.170*0.974) = 0.16558--------------1 

From 1 and 2 
tan θ = 2.41 

θ = 74.96º 
Substituting the value of θ in 
0.130*v cos θ = 0.0687 

v = 1.38 m/s

An ac generator consists of a coil with 40 turns of wire, each with an area of 0.06 m2. The coil rotates in a uniform magnetic f
Reptile [31]

Answer:

331.75 V

Explanation:

Given:

Number of turns of the coil, N = 40 turns

Area, A = 0.06 m²

Magnetic Field, B = 0.4 T

Frequency, f = 55 Hz

                           Maximum induce emf, E₀ = NABω

but ω = 2πf

                           Maximum induce emf, E₀ = NAB(2πf₀)

                           Maximum induce emf, E₀ = 2πNABf₀

Where;

N is number of turns of the coil

A is area

B is magnetic field

ω is the angular velocity

f is the frequency

                                     E₀ = 2 × π × 40 × 0.06 × 0.4 × 55

                                     E₀ = 342.81 V

The maximum induced emf is 331.75 V

can you help me create a sketch of two different objects with one that has a greater density than the other?
sergey [27]

I don't know how good you are at sketching ... I'm terrible. 
But you can put the point across in a dramatic way if you
can sketch a bowling ball and a basketball ... you'll need
to clearly identify them with the markings you sketch on
each ball. 

They're the same shape and nearly the same size, but
there's a huge difference in their densities.
