A larger object is made of two balls separated by a massless rigid rod that is 1.5 m long. The mass of the red ball at one end i
lions [1.4K]

Answer:

The speed of the 1 kg red ball 8.04 m/s .

Explanation:

Given :

Separation between rods , d = 1.5 m .

Mass of the red ball is 1 kg .

Mass of the orange ball is 5.7 kg .

Angular velocity , \omega=1\ rev/s = 2\pi\ rad/s .

Now , distance of center of mass  from red ball is :

r =\dfrac{0\times 1+1.5\times 5.7}{1+5.7}\\\\r = 1.28\ m

We know , speed is given by :

v=\omega r\\\\v=2 \times \pi \times  1.28\\\\v=8.04\ m/s

Hence , this is the required solution .

What does newton's first law describes​
dezoksy [38]
Earlier, we stated Newton's first law as “A body at rest remains at rest or, if in motion, remains in motion at constant velocity unless acted on by a net external force.” It can also be stated as “Every body remains in its state of uniform motion in a straight line unless it is compelled to change that state by forces
For example-A stationary object with no outside force will not move. With no outside forces, a moving object will not stop. An astronaut who has their screwdriver knocked into space will see the screwdriver continue on at the same speed and direction forever.

natka813 [3]

Answer:

1.147 %

Explanation:

\rho = Density of mercury = 1.36\times 10^4\ kg/m^3

g = Acceleration due to gravity = 9.81 m/s²

h = Height of mercury = 8.69 m

Standard atmospheric pressure = 1.01\times 10^5\ Pa

6.55 mmHg converting to Pa

\rho gh\\ =1.36\times 10^4\times 9.81\times 8.69\times 10^{-3}\\ =1159.38504\ Pa

Dividing air pressure by the above value

\frac{1159.38504}{1.01\times 10^5}\times 100=1.147\ \%

The fraction of atmospheric pressure is 1.147 %
