Answer: F=0.075N

Explanation:

T*cos(θ) = mg=0.005X9.8

T*cos(θ)=0.049N

T = 0.049/cosθ

F = k*q1*q2 / r2

F = 8.9875 * 10^9 * q1*q2 / r^2 q1

F = 8.9875 * 10^9 * (5 x 10^-6)^2 / r^2

F=0.2246875/r^2

r= 2Lsinθ = 2 x 1 x sinθ =2sinθ

Kindly check the attached for further solution

A negative slope on the velocity vs. time graph indicates that the object is not
Svetlanka [38]

Answer: False, I think

Explanation:

Well it depends. Its hard to say without a function of the graph. Given a velocity graph, the first derivative is the acceleration.

Negative slope on a velocity graph means you are going in the negative direction. And over time, your velocity per unit of time is also decreasing. That means we are accelerating in the negative direction

I takes you 42 minutes to travel 32 miles to Ann Arbor. What was your<br> speed getting there?
frez [133]

Answer: 45.71 mi/h

Explanation:

Speed S is defined a:

S=\frac{d}{t}

Where:

d=32 miles is the traveled distance

t=42 min \frac{1 h}{60 min}=0.7 h is the time

Solving:

S=\frac{32 miles}{0.7 h}

S=45.71 mi/h This is the speed

Do magnets have to touch each other in order to experience a magnetic<br> force? Explain
tiny-mole [99]
Magnets don’t need to touch each other in order to be magnetic because all objects have an attraction however, the closer the magnets get, the more magnetic it is.

A net force of 2070N acts on a car with a mass of 1350 kg. What is the acceleration of the car?
emmasim [6.3K]

Answer:

Below

Explanation:

To find the acceleration of the car, we can use this formula :

     acceleration = net force / mass

     acceleration = 2070 N / 1350 kg

     acceleration = 1.53333 m/s^2

     acceleration = 1.53 m/s^2

Hope this helps!
