<span>If you wanted to know what the mid-atlantic ocean ridge is, you should observe how it behaves. It's divergent because it pushes away the two tectonic plates that were there before. It separated the continents, that is, the Euro-Africa part from the two Americas and pushed them away from each other to where they are.</span>

A rock is dropped in a pond, causing circular ripples. The radius increased with a rate 1 foot per second. When the radius is 4
Brrunno [24]

Answer:

true

Explanation:

Area = πr²

Differentiating in respect to r

we get,

dA/dr = 2πr

using chain rule,

\frac{dA}{dt} = \frac{dA}{dr} .\frac{dr}{dt}  = 2\pi \frac{dr}{dt}

since r = 4feet

so ,

2π(4) = 8π

A uniform solid disk of radius 1.60 m and mass 2.30 kg rolls without slipping to the bottom of an inclined plane. If the angular
bagirrra123 [75]

To solve this problem we will use the concepts related to energy conservation. Both potential energy, such as rotational and linear kinetic energy, must be conserved, and the gain in kinetic energy must be proportional to the loss in potential energy and vice versa. This is mathematically

PE = KE_{lineal} + KE_{rotational}

mgh = \frac{1}{2}mv^2 +\frac{1}{2} I\omega^2

Where,

m = mass

v = Tangential Velocity

\omega = Angular velocity

I = Moment of Inertia

g = Gravity

Replacing the value of Inertia in a Disk and rearranging to find h, we have

mgh = \frac{1}{2}mv^2 +\frac{1}{2} I\omega^2

mgh = \frac{1}{2}mr^2\omega^2 + \frac{1}{2}(\frac{1}{2}mr^2)\omega^2 )

h = \frac{3}{4} \frac{r^2\omega^2}{g}

Replacing,

h = \frac{3}{4} \frac{(1.6)^2 (5.35)^2}{9.8}

h = 5.607m

Therefore the height of the inclined plane is 5.6m

You are traveling in a car that is moving at a velocity of 30 m/s. Suddenly, a car 15 meters in front of you slams on its brakes
Artemon [7]

Answer:

The acceleration of car is 6.67 m/s².

Explanation:

Given that,

Initial velocity = 30 m/s

Distance = 15 m

Final velocity = 10 m/s

Time = 3 sec

We need to calculate the acceleration

Using formula of acceleration

a=\dfrac{v_{f}-v_{i}}{t}

a=\dfrac{10-30}{3}

a=\dfrac{-20}{3}

a=-6.67\ m/s^2

Negative sign shows the car is slowing down.

Hence, The acceleration of car is 6.67 m/s².
