A soccer ball is rolling with a constant acceleration of -1.5 m/s2 . At ti = 0 s, the ball has an instantaneous velocity of 14 m
miskamm [114]

Answer:

v_{f} = 9.5\,\frac{m}{s}

Explanation:

The final velocity is:

v_{f} = v_{o} + a \cdot t

v_{f} = 14\,\frac{m}{s} + (-1.5\,\frac{m}{s^{2}} )\cdot (3\,s)

v_{f} = 9.5\,\frac{m}{s}

what is the acceleration of a 2,000- kilogram truck if a force of 4,200. N is used to make it start moving forward?
cupoosta [38]

Newton's 2nd law of motion:              Force = (mass) x (acceleration)

Divide each side by (mass) :              Acceleration = (force) / (mass)

       Acceleration of the truck = (4,200 N) / (2,000 kg) = 2.1 m/s²

How does the surface tension of water compared with the surface tension of most other liquids?
Anuta_ua [19.1K]
Surface tension is the direct measure of the cohesive forces between liquid molecules that allows them to form "film", making it more difficult to move an object through the liquid surface. Compared to other known liqiuds, the surface tension of water is much greater.

Lisa [10]

Answer:

The options are

A) isochoric.

B) isothermal.

C) adiabatic.

D) isobaric.

The answer is C. Adiabatic

Adiabatic process involves zero loss or gain of heat in a system. This is usually depicted as Q= 0.

An ideal gas being compressed in a well-insulated chamber using a well-insulated piston involves the use of adiabatic process. The insulated chamber and piston helps to prevent heat loss or gain of heat. This is because insulators are poor conductors of heat and electricity.
