# Amachine part has the shape of a solid uniform sphere of mass 250 g and a diameter of 4.30 cm. it is spinning about a frictionless axle through its center, but at one point on its equator it is scraping against metal, resulting in a friction force of 0.0200 n at that point. part (a): find its angular acceleration. let the direction the sphere is spinning be the positive sense of rotation. part (b): how long will it take to decrease its rotational speed by 21.0 rad/s?   ### Other questions on the subject: Physics Physics, 22.06.2019 03:40, srtero
Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air​ resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the​ time(s) that the projectile will​ (a) reach a height of 192 ft and​ (b) return to the ground when v 0equals112 feet per second. ​(a) find the​ time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
