Answer
given,
largest diameter of balls = 9.52 mm = 0.00476 m
radius = 0.00476
smallest diameter of ball = 2.38 mm = 0.00238 m
radius = 0.00119
viscosity = 1.5 Pa.s
density of the ball = 1.42 g/cm
for small balls
t = 0.033 ms
for larger ball
t = 0.531 ms
Explanation:
it has no energy when considered with respect to earth ,as it has neither height (i e potential energy) nor velocity (i.e kinetic energy).
Explanation:
003 (part 1 of 2)
Pressure is force divided by area.
P = F / A
P = (117 kg × 9.8 m/s²) / (2 × (0.05 m)²)
P = 229,320 Pa
003 (part 2 of 2)
There are approximately 6895 Pa in 1 psi.
P = 229,320 Pa × (1 psi / 6895 Pa)
P = 33.3 psi
004 (part 1 of 2)
Since the collisions are elastic, the angle of reflection is the same as the angle of incidence (it bounces off at the same angle).
Impulse = change in momentum
F Δt = m Δv
F (36 s) = (300 × 0.003 kg) (5.2 sin 57° m/s − (-5.2 sin 57° m/s))
F = 0.218 N
004 (part 2 of 2)
Pressure is force over area.
P = F / A
P = 0.218 N / 0.712 m²
P = 0.306 N/m²

➷ When electrons are lost, a positive ion is formed. This is because there are now more protons than electrons causing the overall charge to be positive.
When electrons are gained, a negative ion is formed. This is because there are now more electrons than protons causing the overall charge to be negative.

So far, I have not been able to run a mile in under 30 minutes.
That proves that I can't do it, but <span>that does not necessarily mean
its impossible. It </span>doesn't prove that nobody else can do it.
Nobody and nothing has ever traveled faster than the speed of light.
That doesn't prove that somebody or something that hasn't tried yet
can't do it. But discoveries in Physics, Quantum Mechanics, Cosmology,
and Relativity, over roughly the past 125 years, which explain and predict
almost everything seen in hundreds of experiments and thousands of
observations since then, do all agree that the speed of light is, let's say,
nature's "speed limit", and that no matter how hard you try, nothing and
nobody CAN travel faster.
