Its when the animal repeats what it is taught similar to a child you never really teach them to lie it just happens because they have seen other people do it

An automobile whose speed is increasing at a rate of 0.800 m/s2 travels along a circular road of radius 10.0 m.

Ket [755]

(a) $a_t = 0.800 m/s^2$

The tangential acceleration component of the car is simply equal to the change of the tangential speed divided by the time taken:

$a_t = \frac{\Delta v}{\Delta t}$

This rate of change is already given by the problem, 0.800 m/s^2, so the tangential acceleration of the car is

$a_t = 0.800 m/s^2$

(b) $a_c = 0.9 m/s^2$

The centripetal acceleration component is given by

$a_c = \frac{v^2}{r}$

where

v is the tangential speed

r is the radius of the trajectory

When the speed is v = 3.00 m/s, the centripetal acceleration is (the radius is r = 10.0 m):

$a_c = \frac{(3.00 m/s)^2}{10.0 m}=0.9 m/s^2$

(c) $1.2 m/s^2, 48.4^{\circ}$

The centripetal acceleration and the tangential acceleration are perpendicular to each other, so the magnitude of the total acceleration can be found by using Pythagorean's theorem:

$a=\sqrt{a_t^2+a_c^2}=\sqrt{(0.8 m/s^2)^2+(0.9 m/s^2)^2}=1.2 m/s^2$

and the direction is given by:

$tan \theta =\frac{a_c}{a_t}=\frac{0.9 m/s^2}{0.8 m/s^2}=1.125\\\theta=tan^{-1}(1.125)=48.4^{\circ}$

where the angle is measured with respect to the direction of the tangential acceleration.

Your roommate is working on his bicycle and has the bike upside down. He spins the 68.0 cm -diameter wheel, and you notice that

MAVERICK [17]

Answer:

a. 6.41 m/s

b. 120.85 m/s^2

Explanation:

The computation is shown below:

a. Pebble speed is

As we know that according to the tangential speed,

$v = r \times \omega$

$= \frac{0.68}{2} \times 18.84$

= 6.41 m/s

The 18.84 come from

$= 2 \times 3.14 \times 3$

= 18.84

b. The pebble acceleration is

$a = \frac{v^2}{r}$

$= \frac{6.41^2}{0.34}$

= 120.85 m/s^2

We simply applied the above formulas so that the pebble speed and the pebble acceleration could come and the same is to be considered

Technician A says that leather shoes offer more protection than canvas shoes. Technician B says that steel toed boots are essent

Sladkaya [172]

Answer: Both technicians A and B

Explanation:

Based on the scenario in the question, it should be noted that leather shoes offer more protection than canvas shoes and that steel toed boots are essential to protecting your feet from injury.

Leather shoes are more durable and offer better protection than canvas. The strength of the material that they're made from can help in offering extra protection which is necessary in an environment where there's possibility of accidents involving falling objects.

Also, for the people who work in a work environment with many heavy machines and equipments, it is vital to it on protective steel toed boots in order to prevent the workers from feet related injuries.
