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?

Answers

Answer 1
Answer:

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

The given values are:

Weight,

  • mg = 500 N

Angle,

  • θ = 100°

As we know,

The sum of vertical forces = 0

then,

\Sigma Fy = 0

Now,

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

Equal amounts of water are kept in a cap and in a dish which will evaporate faster ?why

Answers

The water in the dish evaporates quickly as the surface area of dish is greater than the surface area of the cap, which enables the water in the dish to evaporate quicker.

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

Answers

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

Now,

By converting 5.5 hours into seconds, we get

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

= 1,188,000

hence,

The speed will be:

= (482803)/(1188000)

= 0.406 or, 0.41 \ m/s

Thus the above answer is right.

Answer:

54.54 miles per hour

Explanation:

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?

Answers

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.
