PLZ HELP I HAVE A TEST TOMORROW If Mr. McD applies a net force of 600 N to his carriage of Thanksgiving groceries causing it to accelerate at a rate
of 3 m/s so he can get from the Safeway to his sweet F150 without getting too wet from the pouring down rain
then what is the mass of carriage with groceries?

Which quantities are scalars? choose all that apply a. distance b. speed c. acceleration d. velocity

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?

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
