PLEASE HELP!!<br> What is osteoporosis? What are the symptoms and treatments?

Korvikt [17]

Explanation:

Osteopetrosis is a condition in which bones become weak and brittle. It causes the body to constantly absorb and replace bone tissue. With osteoporosis, new bone creation doesn't keep up with old bone removal.

While some don't experience symptoms, common symptoms can include bone fracture and a decrease in height.

Most treatments include supplements and diet modifications.

A 20-kg barrel is rolled up a 20-m ramp to the back of a truck whose floor is 5.0 m above the ground. What work is done in loadi

oee [108]

The angle of inclination is calculated using sin function,

sin θ = 5 m / 20 m = 0.25

θ = 14.4775°

<span>The net force exerted is then calculated:
F net = m g sin θ = 20 * 9.8 * 0.25 </span>

F net = 49N

<span>Work is product of net force and distance:
W = F net * d = 49 * 20 </span>

An electric field of 280000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of -

nordsb [41]

<h2>The magnitude of the force that acts on a charge of -7.9C at this spot is 2.21 x 10⁶ N.</h2>

Explanation:

Electric field is the ratio of force and charge.

Electric field, E = 280000 N/C

Charge, q = -7.9 C

We have

$E=\frac{F}{q}\\\\280000=\frac{F}{7.9}\\\\F=280000\times 7.9\\\\F=2.21\times 10^6N$

The magnitude of the force that acts on a charge of -7.9C at this spot is 2.21 x 10⁶ N.

A 15.0 volt storage battery is connected to three resistors, 7.75?, 15.5?, and 21.7?, respectively. the resistors are joined in

Rainbow [258]

Total resistance= 7.75+15.5+21.7=44.95
Current = 15V/44.95=0.334A
