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])

Loops in a motor rotate because?
Answer:
Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process

1. A body weighing 2 kg moves in a straight line with a speed of 72 km / h. If the force 10N will act on the body, after how long will its speed become 30m / s?
Answer:
It's an uniformly accelerated motionVf=at +v0v0=72 km/h:3.6=20 m/s
a=F/m=10/2=5m/s^2
t=(vf-v0)/a
t= (30-20)/5=10/5=2s
Determine the stopping location of the prize wheel. At this moment it is centered on the number 11. It is spinning at a rate of 124.40 rpm. It is slowing at a rate of 1.400 rad/s/s.
Predict the time the wheel will remain spinning, the angular displacement it will go through, and then use this to predict the number on which the wheel will stop. To be safe, you will also get one number the right and to the left of the number you chose.
Answer:
The wheel spins for 11.43s. The number cannot be determined.
Explanation:
We know that initial velocity is 124.4 rpm = 13.027137522 rad/s, acceleration is -1.14 rad/s^2, and final velocity is assumed to be 0 rad/s. We are asked to find t and displacement. We use the equation [tex]\omega=\omega_0+\alpha t[/tex] where [tex]\omega=0 rad/s[/tex], [tex]\omega_0=13.027 rad/s[/tex], [tex]\alpha=-1.14rad/s^2[/tex], and [tex]t=?[/tex].
Rearrange the equation to obtain [tex]\frac{\omega-\omega_0}{\alpha}=t[/tex]. Plug in the numbers and solve to obtain [tex]t=11.43s[/tex].
The number of the wheel cannot be determined as we do not know the placement of numbers on the wheel.

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
George walks to a friend's house. He walks 750 meters North, then realizes he walked
too far. He turns around and walks 250 meters South. The entire walk takes him 13
seconds.
Answer:
I think you are looking for the velocity, so the answer is 38.5 m/s
Explanation:
Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.

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

2. A rock is dropped from rest at the top of a 10 meter tall building. How much time does the rock
take to hit the ground?
Answer:
1.4 seconds
Explanation:
here u= 0
v= ?
h= 10m
g= 9.8 m/ s*2
using 2as = v^2 - u ^2
2x9.8x10 = v^2 - 0
v^2 = 196
v = 14 m
time = v- u/ a
14 / 98
1.4 seconds
