A body of mass 8 kg moves in a (counterclockwise) circular path of radius 10 meters, making one revolution every 10 seconds. You

Sav [38]

Answer:

Centripetal force is equal to 31.55 N

Explanation:

We have given mass of the body m = 8 kg

Radius of the circular path r = 10 m

It is given that it makes 1 revolution in 10 seconds

Distance traveled in 10 seconds is equal to $d=2\pi r=2\times 3.14\times 10=62.8m$

Velocity is equal to $velocity=\frac{distance}{time}=\frac{62.8}{10}=6.28m/sec$

We have to find the centripetal force

Centripetal force is equal to $F=\frac{mv^2}{r}=\frac{8\times 6.28^2}{10}=31.55N$

So centripetal force will be equal to 31.55 N

A) Calculate the pressure of water at the bottom of a well if the depth

Molodets [167]

Answer: 98000pa

Explanation:Given,

Depth(h)=10m

gravity(g)=9.8m/s

density(δ)=1000kg/m^3

we know,

P=hdg

P=10*1000*9.8

P=98000pa

Please somebody help i took screenshot ik there is a blank space but look down a little

Dahasolnce [82]

Answer:

Force has a direct relationship to mass and acceleration. Newton's Second Law, force equals mass times acceleration (F=MA), illustrates their general relationship in an equation.

Explanation:

Relationships to remember:

Force and acceleration have a direct relationship, meaning if force increases, acceleration will also increase and vice versa

(Ex: The harder you push a box, the faster it will move)

Mass and acceleration have an inverse relationship, meaning if mass increases, acceleration will decrease and vice versa

(Ex: If you add more furniture in the back of a moving company truck, the truck will move slower than it did before the furniture was added)

Force and mass have a direct relationship, meaning if mass increases, force will also increase

(Ex: You will need to exert less force to lift a 5-pound weight than a 10-pound weight)

And of course, Newton's Second Law, F=MA sums all of this up in 3 letters and a symbol! If you have any more questions about this problem, please comment on my answer :)
