A large sphere has a mass of 175 kg and is suspended by a chain from the ceiling. The mass of the chain is 12.0 kg. What is the

Each point in the chain supports the weight of all the mass below it.

At the bottom end of the chain, the weight is  (175 x 9.8) = 1,715 N .
At the top of the chain, the weight is  (175 + 12) x (9.8) = 1,833 N .

The tension in the chain varies linearly from  1,715N  at the bottom
to  1,833N  at the top.

A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling
Natalka [10]

Answer:

H = 5 m

Explanation:

As the person leaves the slide horizontally so the time taken by the person to hit the water is given as

t = 0.672 s

so we can find the vertical velocity by which person will hit the water using kinematics

v_y = u_y + at

v_y = 0 + (9.81)(0.672)

v_y = 6.6 m/s

now the speed of the person at the end of the slide is given as

v = \frac{L}{t}

v = \frac{5}{0.672}

v_x = 7.44 m/s

now by energy conservation we can find the initial height

mgH = \frac{1}{2}m(v_x^2 + v_y^2)

H = \frac{1}{2g}(v_x^2 + v_y^2)

H = \frac{1}{2(9.81)}(7.44^2 + 6.6^2)

H = 5 m

A body on the surface of a planet with the same radius as Earths weighs 10 times more than it does on Earth. What is the mass of
nadya68 [22]

Answer:

Explanation:

Given

radius of Planet is equal to radius of Earth

r_p=r_e

Weight of body on Planet F_p=mg_p

where m=mass of body

g_p=acceleration\ due\ to\ gravity\ on\ surface\ of\ Planet

Weight of body on earth F_e=mg_e

g_e=acceleration\ due\ to\ gravity\ on\ Earth

acceleration due to gravity is given by

g=\frac{GM}{r^2}

where G=gravitational constant

M=mass of Planet

r=radius of planet

for earth g_e=\frac{GM_e}{r_e^2}

for planet g_p=\frac{GM_p}{r_p^2}

substituting these values in F_e and F_p

F_p=m\times \frac{GM_p}{r_p^2}---1

F_e=m\times \frac{GM_e}{r_e^2}---2

divide 1 and 2

\frac{F_p}{F_e}=\frac{m\times \frac{GM_p}{r_p^2}}{m\times \frac{GM_e}{r_e^2}}

10=\frac{M_p}{M_e}

M_p=10M_e

A student tests the electrical conduction of four materials.
ella [17]

Answer:

A. aluminum, iron, and silver only

Explanation:

metal elements are great conductors; aluminum, iron, and silver are all metals.

plastic isn't an element, but it still doesn't conduct electricity very well because it isn't a metal

(so I would leave out plastic, because you can only choose 3 max based on the answer choices)
