A ball that is attached to a string travels in a horizontal, circular path, as shown in Figure 1. At time t0 , the ball has a sp
Levart [38]

Answer:

F₁ = 4 F₀

Explanation:

The force applied on the string by the ball attached to it, while in circular motion will be equal to the centripetal force. Therefore, at time t₀, the force on ball F₀ is given as:

F₀ = mv₀²/r   --------------- equation (1)

where,

F₀ = Force on string at t₀

m = mass of ball

v₀ = speed of ball at t₀

r = radius of circular path

Now, at time t₁:

v₁ = 2v₀

F₁ = mv₁²/r

F₁ = m(2v₀)²/r

F₁ = 4 mv₀²/r

using equation (1):

<u>F₁ = 4 F₀</u>

Why isn't direct current used in transformers​
Furkat [3]

Answer:

No, it will not and this has a historical importance. The reason is that transformers work via induction of electrical forces by changes in magnetic fields, so the constat fields produced by dc currents won't work at all

Can anybody help me solve this problem? Thank you so much!
ser-zykov [4K]
Please ignore my comment -- mass is not needed, here is how to solve it. pls do the math

at bottom box has only kinetic energy
ke = (1/2)mv^2
v = initial velocity
moving up until rest work done = Fs
F = kinetic fiction force = uN = umg x cos(a)
s = distance travel = h/sin(a)
h = height at top
a = slope angle
u = kinetic fiction
work = Fs = umgh x cot(a)
ke = work (use all ke to do work)
(1/2)mv^2 = umgh x cot(a)
u = (1/2)v^2 x tan (a) / gh

In physics, a field refers to a quantity that has a value for every point in a space. In a sense, a field is like a function in
enyata [817]

Answer:

Explanation:

a ) Temperature at ground level is a field and it is scalar field .At any point in space near ground level  , the temperature is specific so it is a field .  It is scalar  because temperature has no direction .

b )

 Wind velocity at 100 feet above the ground is also a field but it is a vector field . At any point in space , the wind velocity is specific so it is a field .  It is vector   because velocity  has a particular  direction at any point .

c )

Gravitational force on Roessler Hall is a vector field because gravitational force also depends on location in space and it has direction.

d )

Height of a person in your group is not a space because it does not depend upon  location is space . It is same for all location .

e )

Height (above sea level) of the ground is a field  because it also depends upon location in space . It is scalar field .

f )

Slope of the surface of the earth is a scalar field .
