A car is traveling in a race.The car went from the initial velocity of 35 to the final velocity of 65 in 5 seconds what is the a
Ann [662]

Answer:

Acceleration = 6m/s²

Explanation:

<u>Given the following data;</u>

Initial velocity = 35m/s

Final velocity = 65m/s

Time = 5 seconds

To find the acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Mathematically, acceleration is given by the equation;

Acceleration (a) = \frac{final \; velocity  -  initial \; velocity}{time}

Where,

  • a is acceleration measured in ms^{-2}
  • v and u is final and initial velocity respectively, measured in ms^{-1}
  • t is time measured in seconds.

Substituting into the equation, we have

a = \frac{65 - 35}{5}

a = \frac{30}{5}

<em>Acceleration = 6m/s²</em>

When a fixed amount of ideal gas goes through an isochoric process:
zvonat [6]

Answer:

the gas does no work.

Explanation:

An isochoric process is a process in which the volume of a gas is kept constant.

The work done by a gas during a transformation is given by:

W=p\Delta V

where

p is the gas pressure

\Delta V is the change in volume of the gas

For an isochoric process, the volume of the gas does not change, so

\Delta V

and so, according to the previous equation, the work done by the gas is zero:

W = 0

Chứng minh V=kq/r từ mối liên hệ giữ E và V
Marat540 [252]

Answer:V=Aq=KQr

Explanation:

Không biết V bạn kí hiệu ở đây là gì nhỉ? Có phải là điện thế?

Điện thế tại 1 điểm trong điện trường được định nghĩa là công làm vật dịch chuyển từ vị trí đó đến vô cùng. V = A/q

Chứng minh thì được, nhưng chỉ e bạn không có hiểu biết về nguyên hàm, tích phân nên không hiểu.

- Xét tại vị trí cách điện tích Q một đoạn x, khi đó điện tích q sẽ chịu 1 lực: dF=KQ.qx2

Điện tích q dịch chuyển 1 khoảng dx rất nhỏ. Khi đó công do lực điện trường gây ra là:

dA=dF.dx=KQ.qx2dx

Công để dịch chuyển điện tích q từ vị trí r đến vô cùng là:

A=∫∞rdA=∫∞rKQ.qx2dx=KQ.qr−KQ.q∞=KQ.qr

Theo đúng định nghĩa: V=Aq=KQr

uppose the bottom block has a mass of 0.4 kg and the top block has a mass of 0.1 kg. What force do you need to exert (in newtons
notsponge [240]

Answer:

 F = 0

Explanation:

Newton's second law is

         F = ma

As in this case the two blocks move with constant speed, it implies that the acceleration is zero, therefore the force applied to the system is zero

       F = 0
