Which of the following objects is in static equilibrium?

Physics

DedPeter [7]3 years ago
6 0

Answer:

b- a bicycle sitting on the ground

Explanation:

'Static' means it's not moving.

So, only the answer listed as "a bicycle sitting on the ground" corresponds to that condition.

All others possible answers describe something that is moving (an apple falling, a motorcycle accelerating, a car moving at a constant speed).  Even if they are going at a constant speed, they are moving, so not static.

A 12.0-g bullet is fi red horizontally into a 100-g wooden block initially at rest on a horizontal surface. After impact, the bl
allochka39001 [22]

Answer:

v_1 = 91.3 m/s

Explanation:

By energy conservation and work energy theorem we can say that after bullet hits the block, it will move on the rough floor and comes to rest

so here work done by frictional force = change in kinetic energy

so we know that

W_f = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2

-\mu mg d = \frac{1}{2}m(v_f^2 - v_i^2)

-0.650(9.81)(7.5) = \frac{1}{2}(0 - v_i^2)

47.8 = \frac{1}{2}v^2

v = 9.78 m/s

now by momentum conservation we have

m_1 v_1 = (m_1 + m_2) v

12 v_1 = (100 + 12) 9.78

v_1 = 91.3 m/s

Which of the following statements is true for a cell placed in beaker containing an isotonic solution?
Korvikt [17]
An isotonic solution is <span>a solution in which concentration or solute is equal to that of a cell placed in it. Thus, the system is in dynamic equilibrium, and so water molecules flow in both directions.
The correct answer is <u>C. w</u></span><span><u>ater molecules flow in both directions at the same rate.</u></span>
