A 0.3-m-radius automobile tire rotates how many revolutions after starting from rest and accelerating at a constant 2.13 rad/s2

Aloiza [94]

Answer:

The automobile tire rotates 91 revolutions

Explanation:

Given;

angular acceleration of the automobile, α = 2.13 rad/s²

time interval, t = 23.2-s

To calculate the number of revolutions, we apply the first kinematic equation;

$\theta = \omega_i \ + \frac{1}{2} \alpha t^2$

the initial angular velocity is zero,

$\theta =0\ + \frac{1}{2} (2.13) (23.2)^2\\\\\theta = 573.2256 \ Rad$

Find how many revolutions that are in 573.2256 Rad

$N = \frac{\theta}{2 \pi} = \frac{573.2256}{2\pi} \\\\N = 91 \ revolutions$

Therefore, the automobile tire rotates 91 revolutions

A fire hose 5 centimeters in diameter is used to fill a 225-liter bucket. If it takes 15 seconds to fill the bucket, what is the

Vika [28.1K]

I believe you ask about speed at the end of the hose:

The volume of the bucket is 225 liters which is equal to 225 $dm^{3}$ .
$V=225dm^{3}$
Hose's cross section can be counted with the typical circle's area formula (with diameter instead of radius, that's why you've got a fraction):
$A=3,14*\frac{d^{2}}{4}}=0,19625dm^{2}$

$225dm^{3}$ are filled within 15 second.

As the bucket is being filled you can say that it's volume is the volume of the water that flowed out of the hose, then:
$V=A*h$
The speed of the water can be counted with equation:
$v=\frac{h}{t}$
After extracting h from the volume's equation you get:
$v=\frac{V}{A*t}$
When you count the fraction you get the answer:
$v=76,43\frac{dm}{s}=0,7643\frac{m}{s}$

How do I solve for time if I have initial velocity and final speed?

xeze [42]

Final speed = initial speed + (acceleration x time)

(final speed - initial speed) = acceleration x time

Time = (final speed - initial speed) / acceleration

Meteoroids are small objects in space, usually made of rock or metal. These bodies often get close to a planet and fall through

ser-zykov [4K]

Answer:

1. A burning streak of light, called a Meteor.

2.The rocky bodies that survives the fall to the planet’s surface are Meteorites.

Explanation:

Let us see the difference between them.

Asteroids: They are the remnants of a broken planet orbiting the sun in between Mars and Saturn. They are small rocky bodies from a tennis ball size to larger ones weighing a few tones.
Meteoroids: They are the small rocky objects of pebble size formed due to the collision of asteroids.
Meteors: These are pebble size objects that enter Earth's atmosphere and burns off by forming streaks of light.
Meteorites: These are rocky objects bigger than meteors than don't burn out completely and fall on the earth's surface.
Comets: These are objects mainly made of dust and ice that orbit the sun in a highly elliptical orbit. This composition makes a long tail when approaching the sun.
