Answer: 343
Explanation: i know it sounds weird but its right
The frequency for the maximum constructive interference will be 343 Hz.
What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
From the constructive interference;
[tex]\rm L_1-L_2 = 2 \lambda \\\\ 2\lambda=8-6 \\\\ \lambda= 1 \ m[/tex]
The frequency is;
[tex]\rm f= \frac{c}{\lambda} \\\\ f= \frac{343}{1} \\\\ f= 343 \ Hz[/tex]
Hence,the frequency for the maximum constructive interference will be 343 Hz.

19. A car accelerates uniformly in a straight line from 10 m/s to 20 m/s in 5 seconds. What is the
acceleration?
Answer:
2 [tex]m/s^{2}[/tex]
Explanation:
Acceleration = [tex]\frac{Final velocity-Initial velocity}{Time}[/tex]
= [tex]\frac{20 - 10}{5}[/tex]
= [tex]\frac{10}{5}[/tex]
= 2 [tex]m/s^{2}[/tex]

at what distance from a 2.45*10^-6 C charge will the electric field be 100 N/C?
Answer:14.8
Explanation:
Trust me
The distance will be = 14.85 m
What is electric field ?A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
given :
Charge (q)= 2.45*[tex]10^{-6}[/tex] C
Electric field (EF) = 100 N/C
to find = ? distance (r)
Electric field = 1/4π∈o * (q/[tex]r^{2}[/tex])
100 = 9 * [tex]10^{9}[/tex] * ( 2.45*[tex]10^{-6}[/tex] / [tex]r^{2}[/tex])
[tex]r^{2}[/tex] = 220.5
r= [tex]\sqrt{220.5}[/tex]
r = 14.85 m

You toss an apple horizontally at 9.5 m/s from a height of 1.8 m. Simultaneously, you drop a peach from the same height. How long does it take the peach to reach the ground?
Answer:
Peach and Apple will take the same time as the gravitional pull acting on both of them is equal.
height of peach=initial velocity*time+1/2*gravitional pull*(time^2)
1.8=0*time+1/2*9.8*time^2
1.8=0+1/2*9.8*time^2
1.8=1/2*9.8*time^2
3.6/9.8=time^2
taaking value of gravitional pull approx to 10
3.6/10=time^2
0.36=time^2
0.6=time
therefore, the time taken is 0.6sec
Explanation:
The time it takes the peach to reach the ground is 0.61 sec
From the question,
We are to determine how long it would take the peach to reach the ground.
From one of the equations of kinematics for free falling objects,
We have that
[tex]H = ut + \frac{1}{2}gt^{2}[/tex]
Where
H is the height
u is the initial velocity,
t is the time
and g is the acceleration due to gravity ( g = 9.8 m/s²)
Since the object is dropped with no velocity, then the initial velocity is 0 m/s
From the given information
H = 1.8 m
u = 0 m/s
Putting the parameters into the formula,
We get
[tex]1.8 = 0(t) + \frac{1}{2}(9.8)t^{2}[/tex]
This becomes
[tex]1.8 = 0 + 4.9t^{2}[/tex]
[tex]1.8 = 4.9t^{2}[/tex]
Then,
[tex]t^{2} = \frac{1.8}{4.9}[/tex]
[tex]t^{2} = 0.367347[/tex]
∴ [tex]t =\sqrt{0.367347}[/tex]
t = 0.60609 sec
t ≅ 0.61 sec
Hence, the time it takes the peach to reach the ground is 0.61 sec

Explanation:
Two students move a box to the left. One student pushes with a force of 100 N to the left, and the other student pulls with a force of 85 N to the left. They move the box 20 m in 7 s. What is the total amount of work done on the box by the students?
Answer:
Resultant Force= F1 - F2
F1= 100N
F2= 85N
Resultant Force= 100N - 85N
R.F = 15N
Workdone= Force x Displacement
Force = 15N
Displacement = 20m
= 15N X 20m
=300Nm or Joules
