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.
