Two wires are used to suspend a sign that weighs 500 N. The two wires make an angle of 100° between each other. If each wire is exerting an equal amount of force how much force does each wire exert?


Answer 1

The force each wire exert will be "390.62 N".

The given values are:


  • mg = 500 N


  • θ = 100°

As we know,

The sum of vertical forces = 0


\Sigma Fy = 0


F Cos (50) +F Cos (50) = mg

By substituting the value, we get

→                   2F Cos (50) = 500

→                                 F = (500)/(2 Cos (50))

→                                     = (500)/(2(0.64))

→                                     = 390.62 \ N

What is the average speed of a car that traveled 300.0 miles in 5.5 hours?


The average speed of will be "0.41 m/s".

Speed and Distance:

According to the question,

Distance = 300.0 miles

Time = 5.5 hours

We know,

300.0 miles = 482803 meters


By converting 5.5 hours into seconds, we get

= 5.5* (60)/(1)* (3600)/(1)

= 1,188,000


The speed will be:

= (482803)/(1188000)

= 0.406 or, 0.41 \ m/s

Thus the above answer is right.

Find out more information about speed here:  


54.54 miles per hour


You do 300 divided by 5.50 to get 54.545454 but you can estimate it to be about 54.54 miles per hour.

So, top average speed of car was 54.54 mph.

What velocity will move an object from 50 m to −50 m in 20 s?


To find the velocity that will move an object from 50 m to -50 m in 20 seconds, we can use the formula for velocity:

Velocity = Displacement / Time

Given that the object moves from 50 m to -50 m, the total displacement is 50 m (from 50 to 0) plus 50 m (from 0 to -50), which equals 100 m. The time taken is 20 seconds.

Plugging the values into the formula, we get:

Velocity = 100 m / 20 s = 5 m/s

Therefore, the velocity required to move the object from 50 m to -50 m in 20 seconds is 5 m/s.

Suppose that you're facing a straight current-carrying conductor, and the current is flowing toward you.The lines of magnetic force at any point in the magnetic field will act in
A. the same direction as the current.
B. a clockwise direction.
C. a counterclockwise direction.
D. the direction opposite to the current.


Right-hand rule reveals a connection between the current and the magnetic field lines in the magnetic field. It is also called Ampere`s right hand screw rule. It determines the direction of the magnetic field surrounding a current carrying wire. The thunb points direction of current and fingers point the direction of magnetic lines of force. Answer: C ) a counterclockwise rotation.

Answer: b. a clockwise direction

A rectangle has a length of 5.50 m and a width of 12.0 m. What are the perimeter and area of this rectangle?


to find the perimeter of the rectangle, you do 2(a) + 2(b), so when you add 11 and 24, you get a perimeter of 35 meters.

to find the area, you multiply a and b together and get an area of 66 meters squared.
