A 0.2 kg baseball is struck with a force of 100 n from a baseball bat. according to newton's 2nd law, what can we determine abou

t the ball's motion while it is in contact with the bat? question 2 options: it has a speed of 500 m/s it has a speed of 0.002 m/s it has an acceleration of 20 m/s/s it has an acceleration of 500 m/s/s it has a speed of 20 m/s it has an acceleration of 0.002 m/s/s

1. According to Newton's second law of motion, when ball contact with bat we can find the acceleration.

acceleration = 500 m/s^{2}

According to Newton's second law,

Force = mass * acceleration

acceleration = Force/Mass

acceleration = 100n/0.2kg

acceleration = 500 m/s^{2}

The volume of an ideal gas is adiabatically reduced from 151 L to 80.6 L. The initial pressure and temperature are 1.50 atm and
Zolol [24]

Answer:

gas is dioatomic

T_f = 330.0 K

\eta = 7.07 mole

Explanation:

Part 1

below equation is used to determine the type Gas by determining \gamma value

\frac{V_{1}}{V_{F}}\gamma=\frac{P_{i}}{P_{f}}

where V_i and V_f is initial and final volume respectively

and P_i and P_f are initial and final pressure

\gamma = \frac{ln(P_f/P_i)}{ln(V_i/V_f)}

\gamma = \frac{ln(3.61/1.50)}{ln(151/80.6}

\gamma = 1.38

therefore gas is dioatomic

Part 2

final temperature in adiabatic process is given as

T_f = T_i*[\frac{v_i}{V_f}](^\gamma-1)

substituing value to get final temperature

T_f = 260*[\frac{151}{80.6}]^ {(1.38-1)}

T_f = 330.0 K

Part 3

determine number of moles by using following formula

\eta =\frac{PV}{RT}

\eta =\frac{1.013*10^{5}*0.151}{8.314*260}

\eta = 7.07 mole

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the w
Makovka662 [10]

Answer: W.D = 1/2mv^2

Explanation:

If an external force or a single force is acting on a body. Just like the first law of thermodynamics, the force acting on the body will cause work done on the system.

Work done = force × distance

And the work done on the body will cause the molecules of the body to experience motion and thereby producing kinetic energy.

The work done will be converted to kinetic energy.

W.D = 1/2mv^2

Ber [7]

Answer:

the force acting on the car is 3600 N

Explanation:

The computation of the force acting on the car is shown below:

As we know that

Force = mass × acceleration

= 1200 kg × 3.0 ms/^2

= 3600 N

hence, the force acting on the car is 3600 N
