The answer is C, or A basketball player pushes into another one and they both fall to the left.

Explanation:

Isaac Newton’s third law states that for every action, there is an equal and opposite reaction. In this instance, there is no reaction in opposition to the basketball players being pushed into each other. Both players fall to the left, and this means that there is no equal and opposite reaction. Therefore, this example does not display Newton’s third law of motion.

A girl of mass 55 kg throws a ball of mass 0.80 kg against a wall. The ball strikes the wall horizontally with a speed of 25 m/s

s2008m [1.1K]

Answer:

$F=800N$

Explanation:

The average force is defined as the mass of the body multiplied by its average velocity over the contact time. According to the third Newton's law, the magnitude of the average force exerted on the wall by the ball is equal to the magnitude of the average force exerted on the ball by the wall. Thus:

$F=m\frac{v_f-v_i}{t}\\F=0.80kg\frac{25\frac{m}{s}-(-25\frac{m}{s})}{0.05s}\\F=800N$

An electrostatic force of 9.0 N ??

dezoksy [38]

<h3><u>Answer</u>:- </h3>

$\longrightarrow \sf D) 9.0 \times 10^6 N/C$

<h3><u>Solution:-</u></h3>

Given -

force,F = 9.0 N
Charge,q = +1.0 $\mu$

Force,F on any charge q in electric field,E is given by -

$\green{ \underline { \boxed{ \sf{F = qE}}}}$

$\therefore \sf E = \dfrac{F}{q}$

Putting Values -

$\begin{gathered}\\\implies\quad \sf \dfrac{9}{1 \times 10^{-6}} \quad(1\mu = 10^{-6}) \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 9 \times 10^{6} N/C \\\end{gathered}$

Is a violin and battery potential energy?

SCORPION-xisa [38]

Explanation:

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The battery is storing the energy but give it something to power and it'll give its energy to the object and a violin strings are like ruber band and if you play the violin it releases a new type of energy sound energy.
