Answer:

The value is F =13.27 \  N

Explanation:

From the question we are told that

     The mass is m = 3200 \ g = 3.2 \ kg

     The speed is v = 7.2 \ m/s

     The radius is r = 12.5 \ m

     

Generally the centripetal force is mathematically represented as

        F = m * \frac{v^2}{r}

=>     F = 3.2 * \frac{7.2^2}{12.5}

=>     F =13.27 \  N

How many stars are contained in the milking way galaxy A) 0 b)1 c) billions d)infinite
skelet666 [1.2K]

Answer:

c) billions

Explanation:

there are more than 0 stars, because our sun is a star

and  there are more than one because the milky way has a lot of suns

there aren't infinite because the milky way is finite it has some volume and even you made the smallest star possible you wouldn't have infinite stars

so the only option is billions

A general contractor drives 5 miles to the hardware store in 10 minutes. He shops for needed tools for 30 minutes, then drives t
Alex17521 [72]

Given parameters:

Distance to hardware shop = 5 miles

Time to reach hardware shop = 10 minutes

Time spent at the shop = 30 minutes

Average speed to customer home = 45 mph

Time taken for the travel = 20 minutes

Unknown:

Average speed of the contractor = ?

Solution:

 Average speed is the total distance covered divided by the total time taken.

   Average speed = \frac{total distance}{total time taken}  

     total distance = distance to hardware shop + distance to customer's home

We do not know the distance to customer's home but we have been given the speed and time, so we can find the distance.

  Distance  = speed x time

 Convert the time to hrs and solve;  

                       60 minutes  = 1 hr

                       20 minutes  = \frac{20}{60} hr  = \frac{1}{3} hr

So, Distance  = 45mph x \frac{1}{3} hr   = 15miles

Now;

   Total distance  = 5 + 15 = 20miles

Total time = time to reach hardware shop + time to reach customer's house

                  = 10 + 20

                  = 30 minutes

Convert the time from minutes to hrs;

                 60 minutes  = 1hr

                 30 minutes  = \frac{30}{60}   = 0.5hr

So;

    Average speed  = \frac{20}{0.5} = 40mph

The average speed is 40mph

Is a process that modifies light waves so they vibrate in a single plane
madam [21]

The process you're fishing for is "polarization", but that's a

misleading description.

Polarization doesn't do anything to change the light waves. 

It simply filters out (absorbs, as with a polarizing filter) the

light waves that aren't vibrating in the desired plane, and

allows only those that are to pass.

The intensity of a light beam is always reduced after

polarizing it, because much (most) of the original light

has been removed.

A laser light source may be thought of as an exception,

since everything coming out of the laser is polarized.

You throw a basketball and a tennis ball across the classroom so that each ball has the exact same momentum. Explain how this is
Helga [31]

Answer:

It is possible by increasing the speed of the tennis ball by a factor of (Mass of the tennis ball)/(Mass of the basketball)

Explanation:

The momentum of a body = The bod's mass × The body's velocity

Therefore, the momentum of a given mass of an object, such as a tennis ball can be increased by increasing the velocity or speed of the object. Whereby the speed of the ball, v₁, is increased such that the momentum of the basketball and the tennis ball will be the same, is given by the following equation

Mass of the basketball × v₂ = Mass of the tennis ball × v₁

Therefore, v₁/v₂ = (Mass of the tennis ball)/(Mass of the basketball)

What is the instantaneous speed of the monkey at time t=5s?
bezimeni [28]
I’m assuming we’re suppose to get some kind of graph but, Instantaneous speed is the speed that is happening right now. Like driving a car at 15k/h. The instantaneous speed of the car 15k/h. On the graph, at 5s. Wherever the line is, will tell you what the speed is.
