45 rpm coincides to 45 transformations per minute.In bespeak to convert into rad/s, we have to keep in mental that:
*
*
so, the element of conversion between rpm and rad/s is:
*
so, the angular speed converted in rad/s becomes:
*


Find the size of the impulse ceded to a football ball when a player kicks it with a pressure of 1450 N . Assume the the pla

surfacetoairnewyork.com:

7.98 Newton Seconds

Explanation:

J = F * (Δt)

J = 1450 (5.5 * 10^-3)

J = 7.975

We only use three significant digits, so our surfacetoairnewyork.com i do not care 9.98



Snells law. N1 • sin of theta 1 = N2 • sin of theta 21.33 • 0.4226 = 1.50 sin of theta 20.5620 = 1.50 sin that theta 20.5620/1.50 = 1.50/1.50 sin that theta 2Sin of theta 2 = 37°

Statement A: Area that a rectangle with measured length = 2.536 m and also width = 1.4 m. Statement B: Area that a rectangle through measure

surfacetoairnewyork.com:

Statement A=3.5504m²

Statement B=3.57576m²

Explanation:

The area of a rectangle is gained by multiply the size of the rectangle through the broad of the rectangle which gives us the surface ar area i beg your pardon the rectangle covers. Because that statement A, ns multiplied 2.536 by 1.4 and also for statement B, i multiplied 2.536 through 1.41



for box A :

gravitational traction is given as

F = G (10) (10) /r²

F = 100 G/r² eq-1

for box B :

gravitational traction is offered as

F" = G (10) (5) /r"²

F" = 50 G/r"² eq-2

for crate C :

gravitational traction is given as

F"" = G (10) (15) /r""²

F"" = 150 G/r""² eq-3

from the chart , we view that

r = r"

hence F > F"

gravitational pull of crate B is higher than gravitational traction of box A.

You are watching: A record rotates on a turntable at 45 rpm

r"" > r = r"

such the r"" is nearly 2 times of r and also r"

so F"" = 150 G/(2r"²)

F"" = 37.5 G/r"² = 37.5 G/r²

hence box A has best gravitational pull in between the objects.

A) the thing inbox A would have the the strongest gravitational pull because they are close to each other and have more mass.

False, because when you shine light through a prism, it separates the shade of irradiate or something and creates a rainbow.
