each cube inside the rectangular prism has an edge length 3/4 inch.What is the volume of the rectangular prism?
NNADVOKAT [17]

Answer:

\frac{27}{64}n\,\,cubic\,\, inches

Step-by-step explanation:

Given: Edge length of cube = \frac{3}{4}\,\,inch

To find: Volume of the rectangular prism

Solution:

A cube is a three-dimensional solid object which has 12 edges, 8 vertices and 6 faces.

A rectangular prism is a solid three-dimensional object which has six faces that are rectangles.

Let n denotes number of cubes inside the rectangular prism

Volume of one cube = (edge)^3=(\frac{3}{4})^3 =\frac{27}{64}  cubic inches

So, volume of rectangular prism = volume of n cubes =  \frac{27}{64}n\,\,cubic\,\, inches

You are at a playground with a see-saw and a large merry-go-round. You put your phone on the see-saw and find it slides when it
12345 [234]

Answer:  r_max = 1.75m

Step-by-step explanation:

Below is a rather brief analysis to solving this problem.

The phone starts sliding when along incline,

when F_net = m g sin(theta) - fs_max = 0  

and fs_max = us N = us m g cos(theta)

m g sin(theta) - us m g cos(theta) =

us = tan(theta) = tan38 = 0.781  

On merry - go - round,

fs_max = us N = us m g

Using F = m a

fs_max = m w^2 r_max and w = 2pi / T

us m g = m (2 pi / T)^2 (r_max)

0.781 x 9.81 = (2 pi / 3)^2 (r_max)

r_max = 1.75 m

cheers i hope this helped !!
