The geologic force applied to rocks is called compression. Compression<span> is the stress that squeezes </span>rocks<span> together. As a result of the c</span>ompression rocks fold or fracture depending on their compressive strength<span> or </span>compression strength<span> - the capacity of a material or structure to withstand loads tending to reduce size.

steposvetlana [31]

Answer:

Average speed of the swimmer is 4.44 m/s

Explanation:

As we know that the speed is the ratio of distance covered over time interval

so here we can say

$v = \frac{d}{t}$

so we know that

$d = 200 m$

time taken to complete the trip is

$t = 45 s$

now we have

$v = \frac{200}{45}$

$v = 4.44 m/s$

In the design of a supermarket, there are to be several ramps connecting different parts of the store. Customers will have to pu

tatuchka [14]

Answer:

3.90 degrees

Explanation:

Let g= 9.81 m/s2. The gravity of the 30kg grocery cart is

W = mg = 30*9.81 = 294.3 N

This gravity is split into 2 components on the ramp, 1 parallel and the other perpendicular to the ramp.

We can calculate the parallel one since it's the one that affects the force required to push up

F = WsinΘ

Since customer would not complain if the force is no more than 20N

F = 20

$294.3sin\theta = 20$

$sin\theta = 20/294.3 = 0.068$

$\theta = sin^{-1}0.068 = 0.068 rad = 0.068*180/\pi \approx 3.90^0$

So the ramp cannot be larger than 3.9 degrees

Janet jumps off a high diving platform with a horizontal velocity of 2.8 meters per second in lands in the_________.

Inessa05 [86]

Answer:

Janet jumps off a high diving platform with a horizontal velocity of 2.89 m per s and lands in the water 1.5 s later. How high is the platform?

Platform is 11.025 meters high .

Explanation:

we have Vx = 2.89 m/s

time taken = 1.5 seconds

height of the platform = ?

so,

As Janet is jumping from a high diving platform from a certain unknown height their must be involvement of gravity in action.

we can use,

h = Vi*t+(1/2)*g*t^2

where ,

h = height

Vi = initial horizontal velocity that will be zero

t = time in seconds

g = gravity due to acceleration

now put the values

h = 0+(1/2)*(9.8)*(1.5)^2

h = 11.025-m
