PHYSICAL SCIENCE A 0.16-kilogram ball attached to a string is being spun in a circle 7.26 meters per second. The expression", where m is the mass of the ball, o is
the velocity, and r is the radius, can be used to find the force that keeps the ball
spinning in a circle. If the circle has a radius of 0.5 meter, find the force that must
be exerted to keep the ball spinning. Round to the nearest tenth.

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
